| 1 | CRISPR/Cas9-mediated PINK1 deletion leads to neurodegeneration in rhesus monkeys显示文摘Dear Editor,PINK1 mutations cause autosomal recessive and early-onset Parkinson’s disease(PD)with selective neurodegeneration.Unfortunately,current PINK1 knockout(KO)mouse1,2 and pig models3,4 are unable to recapitulate the selective and overt neurodegeneration seen in PD patients.Furthermore,endogenous Pink1 in the mouse brain is expressed at very low levels and can only be detected via immunoprecipitation,5 meaning that PINK1’s function in the mammalian brain needs to be assessed using larger animals that are closer to humans.We previously used CRISPR/Cas9 to target the monkey gene in one-cell stage embryos.6 Using the same approach,we designed two gRNAs to target exon 2(T1)and exon 4(T2),which encode a kinase domain in the PINK1 gene of rhesus monkeys(Fig.1a).CRISPR/Cas9 and PINK1 gRNAs were injected into one-cell stage rhesus monkey embryos.A T7E1 assay and sequencing of PCR products from the injected embryos showed high efficiency(61.5%)in targeting PINK1(Fig.1b and Supplementary information,Fig.S1).Transfer of 87 embryos to 28 surrogate rhesus monkeys resulted in 11 pregnancies(39.2%)(Fig.1b).Eleven fetuses developed to term and were born naturally.Of these live monkeys,eight carried PINK1 mutations(M),and three were wild type(WT).However,three mutant monkeys(M1,M3 and M4)were newborn triplets that struggled to survive and died 3-4 days after birth.One WT newborn monkey also died after a difficult labor.Another mutant monkey(M2)died 7 days after birth without noticeable warning signs or symptoms.The other three mutant monkeys(M6,M7 and M8)have lived for three years;M5,however,reduced its food intake and showed weakness at the age of 1.5 years,and died 30 days after anesthesia for MRI examination. | Weili Yang Yunbo Liu Zhuchi Tu Chong Xiao Sen Yan Xishan Ma Xiangyu Guo Xiusheng Chen Peng Yin Zhengyi Yang Su Yang Tianzi Jiang Shihua Li Chuan Qin Xiao-Jiang Li | 2019 | Cell Research2019，29，4： | 12 |
| 2 | Spinal Cord Stimulation Frequency Influences the Hemodynamic Response in Patients with Disorders of Consciousness显示文摘Spinal cord stimulation(SCS) is a promising technique for treating disorders of consciousness(DOCs).However, differences in the spatio-temporal responsiveness of the brain under varied SCS parameters remain unclear. In this pilot study, functional near-infrared spectroscopy was used to measure the hemodynamic responses of 10 DOC patients to different SCS frequencies(5 Hz, 10 Hz, 50 Hz, 70 Hz, and 100 Hz). In the prefrontal cortex, a key area in consciousness circuits, we found significantly increased hemodynamic responses at 70 Hz and 100 Hz, and significantly different hemodynamic responses between 50 Hz and 70 Hz/100 Hz. In addition, the functional connectivity between prefrontal and occipital areas was significantly improved with SCS at 70 Hz. These results demonstrated that SCS modulates the hemodynamic responses and long-range connectivity in a frequency-specific manner(with 70 Hz apparently better), perhaps by improving the cerebral blood volume and information transmission through the reticular formation-thalamus-cortex pathway. | Juanning Si Yuanyuan Dang Yujin Zhang Yaxin Li Wenyue Zhang Yi Yang Yue Cui Xiaoping Lou Jianghong He Tianzi Jiang | 2018 | Neuroscience Bulletin2018，34，4： | 10 |
| 3 | Prefrontal cortex and the dysconnectivity hypothesis of schizophrenia显示文摘Schizophrenia is hypothesized to arise from disrupted brain connectivity. This 'dysconnectivity hypothesis' has generated interest in discovering whether there is anatomical and functional dysconnectivity between the prefrontal cortex(PFC) and other brain regions, and how this dysconnectivity is linked to the impaired cognitive functions and aberrant behaviors of schizophrenia. Critical advances in neuroimaging technologies, including diffusion tensor imaging(DTI) and functional magnetic resonance imaging(f MRI), make it possible to explore these issues. DTI affords the possibility to explore anatomical connectivity in the human brain in vivo and f MRI can be used to make inferences about functional connections between brain regions. In this review, we present major advances in the understanding of PFC anatomical and functional dysconnectivity and their implications in schizophrenia. We then briefl y discuss future prospects that need to be explored in order to move beyond simple mapping of connectivity changes to elucidate the neuronal mechanisms underlying schizophrenia. | Yuan Zhou Lingzhong Fan Chenxiang Qiu Tianzi Jiang | 2015 | Neuroscience Bulletin2015，31，2： | 9 |
| 4 | A review of functional magnetic resonance imaging for Brainnetome显示文摘The functional brain network using blood-oxygen-level-dependent(BOLD) functional magnetic resonance imaging(fMRI) has revealed the potentials for probing brain architecture,as well as for identifying clinical biomarkers for brain diseases.In the general context of Brainnetome,this review focuses on the development of approaches for modeling and analyzing functional brain networks with BOLD fMRI.The prospects for these approaches are also discussed. | Ming Song Tianzi Jiang | 2012 | Neuroscience Bulletin2012，28，4： | 9 |
| 5 | The long rather than the short allele of 5-HTTLPR predisposes Han Chinese to anxiety and reduced connectivity between prefrontal cortex and amygdala显示文摘The short allele of the serotonin-transporter gene is associated with higher risk for anxiety and depression in Caucasians, but this association is still unclear in Asians. Here, we addressed this issue using behavioral and multi-modal MRI approaches in a large group of healthy Han Chinese participants (n = 233). In contrast to findings in Caucasians, we found that long-allele (L) carriers had higher anxiety scores. In another group (n = 64) experiencing significant levels of depression or anxiety, the L-allele frequency was also significantly higher. In healthy participants, L-carriers had reduced functional and anatomical connectivity between the amygdala and prefrontal cortex (PFC), which was correlated with anxiety or depression scores. Our findings demonstrated that in Chinese Han participants, in contrast to Caucasians, the L-allele confers vulnerability to anxiety or depression and weakens top-down emotional control between the PFC and amygdala. Therefore, ethnic background should be taken into account in gene-related studies and their potential clinical applications. | Haixia Long Bing Liu Bing Hou Chao Wang Jin Li Wen Qin Dawei Wang Yuan Zhou Keith M.

| 6 | Brain Network Studies in Chronic Disorders of Consciousness:Advances and Perspectives显示文摘Neuroimaging has opened new opportunities to study the neural correlates of consciousness, and provided additional information concerning diagnosis, prognosis, and therapeutic interventions in patients with disorders of consciousness. Here, we aim to review neuroimaging studies in chronic disorders of consciousness from the viewpoint of the brain network, focusing on positron emission tomography, functional MRI, functional near-infrared spectroscopy,electrophysiology, and diffusion MRI. To accelerate basic research on disorders of consciousness and provide a panoramic view of unconsciousness, we propose that it is urgent to integrate different techniques at various spatiotemporal scales, and to merge fragmented findings into a uniform‘‘Brainnetome''(Brain-net-ome) research framework. | Ming Song Yujin Zhang Yue Cui Yi Yang Tianzi Jiang | 2018 | Neuroscience Bulletin2018，34，4： | 8 |
| 7 | Separate Neural Networks for Gains and Losses in Intertemporal Choice显示文摘An important and unresolved question is how human brain regions process information and interact with each other in intertemporal choice related to gains and losses. Using psychophysiological interaction and dynamic causal modeling analyses, we investigated the functional interactions between regions involved in the decisionmaking process while participants performed temporal discounting tasks in both the gains and losses domains. We found two distinct intrinsic valuation systems underlying temporal discounting in the gains and losses domains:gains were specifically evaluated in the medial regions,including the medial prefrontal and orbitofrontal cortices,and losses were evaluated in the lateral dorsolateral prefrontal cortex. In addition, immediate reward or punishment was found to modulate the functional interactions between the dorsolateral prefrontal cortex and distinct regions in both the gains and losses domains: in the gains domain, the mesolimbic regions; in the losses domain, the medial prefrontal cortex, anterior cingulate cortex, and insula. These findings suggest that intertemporal choice of gains and losses might involve distinct valuation systems,and more importantly, separate neural interactions may implement the intertemporal choices of gains and losses.These findings may provide a new biological perspective for understanding the neural mechanisms underlying intertemporal choice of gains and losses. | Yang-Yang Zhang Lijuan Xu Zhu-Yuan Liang Kun Wang Bing Hou Yuan Zhou Shu Li Tianzi Jiang | 2018 | Neuroscience Bulletin2018，34，5： | 6 |
| 8 | Complement C7 is a novel risk gene for Alzheimer's disease in Han Chinese显示文摘Alzheimer's disease is the most common neurodegenerative disease,and has a high level of genetic heritability and population heterogeneity.In this study,we performed the whole-exome sequencing of Han Chinese patients with familial and/or early-onset Alzheimer's disease,followed by independent validation,imaging analysis and function characterization.We identified an exome-wide significant rare missense variant rs3792646(p.K420Q)in the C7 gene in the discovery stage(P=1.09×10^(-6),odds ratio=7.853)and confirmed the association in different cohorts and a combined sample(1615 cases and 2832 controls,P_(combined)=2.99×10^(-7),odds ratio=1.930).The risk allele was associated with decreased hippocampal volume and poorer working memory performance in early adulthood,thus resulting in an earlier age of disease onset.Overexpression of the mutant p.K420Q disturbed cell viability,immune activation and β-amyloid processing.Electrophysiological analyses showed that the mutant p.K420Q impairs the inhibitory effect of wild type C7 on the excitatory synaptic transmission in pyramidal neurons.These findings suggested that C7 is a novel risk gene for Alzheimer’s disease in Han Chinese. | Deng-Feng Zhang Yu Fan Min Xu Guihong Wang Dong Wang Jin Li Li-Li Kong Hejiang Zhou Rongcan Luo Rui Bi Yong Wu Guo-Dong Li Ming Li Xiong-Jian Luo Hong-Yan Jiang Liwen Tan Chunjiu Zhong Yiru Fang Chen Zhang Nengyin Sheng Tianzi Jiang Yong-Gang Yao | 2019 | National Science Review2019，6，2： | 6 |
| 9 | An App knock-in rat model for Alzheimer’s disease exhibiting Aβand tau pathologies,neuronal death and cognitive impairments显示文摘A major obstacle in Alzheimer’s disease(AD)research is the lack of predictive and translatable animal models that reflect disease progression and drug efficacy.Transgenic mice overexpressing amyloid precursor protein(App)gene manifest non-physiological and ectopic expression of APP and its fragments in the brain,which is not observed in AD patients.The App knock-in mice circumvented some of these problems,but they do not exhibit tau pathology and neuronal death.We have generated a rat model,with three familiar App mutations and humanized Aβsequence knocked into the rat App gene.Without altering the levels of full-length APP and other APP fragments,this model exhibits pathologies and disease progression resembling those in human patients:deposit of Aβplaques in relevant brain regions,microglia activation and gliosis,progressive synaptic degeneration and AD-relevant cognitive deficits.Interestingly,we have observed tau pathology,neuronal apoptosis and necroptosis and brain atrophy,phenotypes rarely seen in other APP models.This App knock-in rat model may serve as a useful tool for AD research,identifying new drug targets and biomarkers,and testing therapeutics. | Keliang Pang Richeng Jiang Wei Zhang Zhengyi Yang Lin-Lin Li Makoto Shimozawa Simone Tambaro Johanna Mayer Baogui Zhang Man Li Jiesi Wang Hang Liu Ailing Yang Xi Chen Jiazheng Liu Bengt Winblad Hua Han Tianzi Jiang Weiwen Wang Per Nilsson Wei Guo Bai Lu | 2022 | Cell Research2022，32，2： | 6 |

| 11 | Precise Modulation Strategies for Transcranial Magnetic Stimulation:Advances and Future Directions显示文摘Transcranial magnetic stimulation(TMS)is a popular modulatory technique for the noninvasive diagnosis and therapy of neurological and psychiatric diseases.Unfortunately,current modulation strategies are only modestly effective.The literature provides strong evidence that the modulatory effects of TMS vary depending on device components and stimulation protocols.These differential effects are important when designing precise modulatory strategies for clinical or research applications.Developments in TMS have been accompanied by advances in combining TMS with neuroimaging techniques,including electroencephalography,functional nearinfrared spectroscopy,functional magnetic resonance imaging,and positron emission tomography.Such studies appear particularly promising as they may not only allow us to probe affected brain areas during TMS but also seem to predict underlying research directions that may enable us to precisely target and remodel impaired cortices or circuits.However,few precise modulation strategies are available,and the long-term safety and efficacy of these strategies need to be confirmed.Here,we review the literature on possible technologies for precise modulation to highlight progress along with limitations with the goal of suggesting future directions for this field. | Gangliang Zhong Zhengyi Yang Tianzi Jiang | 2021 | Neuroscience Bulletin2021，37，12： | 4 |
| 12 | Wearable wireless real-time cerebral oximeter for measuring regional cerebral oxygen saturation显示文摘Monitoring regional cerebral oxygen saturation throughout the perioperative clinical process is important for successful patient outcomes.Cerebral oximeters based on near-infrared spectroscopy(NIRS)have already been used for monitoring brain oxygenation and hemodynamics to avoid intraoperative ischemic stroke and reduce postoperative cognitive dysfunction.The current devices are all designed to be used as a bedside monitor,limiting their use to situations that center around a hospital bed.There is a current lack of wearable,miniaturized,wireless equipment that can extend brain oxygenation monitoring to motion tasks or tight spaces.We design a head-mounted wearable wireless oxygen saturation monitoring on head(WORTH)band based on NIRS for monitoring regional cerebral oxygen saturation.The band is embedded with a highly integrated central block,which comprises an optical module,a microprocessor unit,a wireless communication module,and a power management module.The performance of the WORTH band is evaluated by a controlled hypoxia experiment and a squat-to-stand experiment.The results confirm that the WORTH band can record cerebral oxygen saturation with an accuracy comparable to that of a clinical monitor and demonstrate that it is also effective during motion tasks. | Juanning SI Xin ZHANG Meng LI Jian YU Zhiyong ZHANG Qing HE Shaohua CHEN Lianqing ZHU Tianzi JIANG | 2021 | Science China(Information Sciences)2021，64，1： | 4 |

| 14 | Diffusion magnetic resonance imaging for Brainnetome:A critical review显示文摘Increasing evidence shows that the human brain is a highly self-organized system that shows attributes of smallworldness,hierarchy and modularity.The 'connectome' was conceived several years ago to identify the underpinning physical connectivities of brain networks.The need for an integration of multi-spatial and-temporal approaches is becoming apparent.Therefore,the 'Brainnetome'(brain-net-ome) project was proposed.Diffusion magnetic resonance imaging(dMRI) is a non-invasive way to study the anatomy of brain networks.Here,we review the principles of dMRI,its methodologies,and some of its clinical applications for the Brainnetome.Future research in this field is discussed. | Nianming Zuo Jian Cheng Tianzi Jiang | 2012 | Neuroscience Bulletin2012，28，4： | 4 |

| 16 | Reconstruction of behavior-relevant individual brain activity:an individualized fMRI study显示文摘Different patterns of brain activity are observed in various subjects across a wide functional domain.However,these individual differences,which are often neglected through the group average,are not yet completely understood.Based on the fundamental assumption that human behavior is rooted in the underlying brain function,we speculated that the individual differences in brain activity are reflected in the individual differences in behavior.Adopting 98 behavioral measures and assessing the brain activity induced at seven task functional magnetic resonance imaging states,we demonstrated that the individual differences in brain activity can be used to predict behavioral measures of individual subjects with high accuracy using the partial least square regression model.In addition,we revealed that behavior-relevant individual differences in brain activity transferred between different task states and can be used to reconstruct individual brain activity.Reconstructed individual brain activity retained certain individual differences which were lost in the group average and could serve as an individual functional localizer.Therefore,our results suggest that the individual differences in brain activity contain behavior-relevant information and should be included in group averaging.Moreover,reconstructed individual brain activity shows a potential use in precise and personalized medicine. | Dongya Wu Xin Li Tianzi Jiang | 2020 | Science China(Life Sciences)2020，63，3： | 3 |
| 17 | ASAF: altered spontaneous activity fingerprinting in Alzheimer’s disease based on multisite fMRI显示文摘Several monocentric studies have noted alterations in spontaneous brain activity in Alzheimer's disease (AD), although there is no consensus on the altered amplitude of low-frequency fluctuations in AD patients. The main aim of the present study was to identify a reliable and reproducible abnormal brain activity pattern in AD. The amplitude of local brain activity (AM), which can provide fast mapping of spontaneous brain activity across the whole brain, was evaluated based on multisite rs-fMRI data for 688 subjects (215 normal controls (NCs), 221 amnestic mild cognitive impairment (aMCI) 252 AD). Two-sample t-tests were used to detect group differences between AD patients and NCs from the same site. Differences in the AM maps were statistically analyzed via the Stouffer's meta-analysis. Consistent regions of lower spontaneous brain activity in the default mode network and increased activity in the bilateral hippocampus/parahippocampus, thalamus, caudate nucleus, orbital part of the middle frontal gyrus and left fusiform were observed in the AD patients compared with those in NCs.

| 18 | Fine-Grained Topography and Modularity of the Macaque Frontal Pole Cortex Revealed by Anatomical Connectivity Profiles显示文摘The frontal pole cortex(FPC)plays key roles in various higher-order functions and is highly developed in non-human primates.An essential missing piece of information is the detailed anatomical connections for finer parcellation of the macaque FPC than provided by the previous tracer results.This is important for understanding the functional architecture of the cerebral cortex.Here,combining cross-validation and principal component analysis,we formed a tractography-based parcellation scheme that applied a machine learning algorithm to divide the macaque FPC(2 males and 6 females)into eight subareas using high-resolution diffusion magnetic resonance imaging with the 9.4 T Bruker system,and then revealed their subregional connections.Furthermore,we applied improved hierarchical clustering to the obtained parcels to probe the modular structure of the subregions,and found that the dorsolateral FPC,which contains an extension to the medial FPC,was mainly connected to regions of the default-mode network.The ventral FPC was mainly involved in the social-interaction network and the dorsal FPC in the metacognitive network.These results enhance our understanding of the anatomy and circuitry of the macaque brain,and contribute to FPC-related clinical research. | Bin He Long Cao Xiaoluan Xia Baogui Zhang Dan Zhang Bo You Lingzhong Fan Tianzi Jiang | 2020 | Neuroscience Bulletin2020，36，12： | 2 |
