Title: Brain Connectivity Atlas and Accurate Neuromodulation
Abstract: Brain connectivity atlas is fundamental for investigating brain functional organization and identifying biomarkers for brain disorders. Traditionally, brain atlas is created with microscopic cytoarchitecture or macroscopic anatomical landmarks in absence of connectivity information which determines the functional segregation. In this talk, I will introduce a series our works to map the brain connectivity atlas based on distinct connectivity profiles, to explore the relationship between different modalities to create the connectivity atlas, and to investigate the evolutional and developmental connectivity atlas.. Finally, I will present using our brain connectivity atlas to guide neuromodulation (rTMS) for investigation of visuospatial attention and for mild Alzheimer’s disease (AD) therapy.

Title: Graph Signal Processing: its Mathematical Theory and Application
Abstract: Graph signal processing has been paid enough attention and developed rapidly in recent ten years. Traditional signal is defined in the real axis or high-dimensional Euclidean space. With the rapid increase of Internet data, data cannot always be regarded as classical functions. A useful model is the signals on graphs. To process this kind of signals, we need to extend the classical Fourier transform, wavelet transform to the graph setting. Many problems in classical signal processing, such as time-frequency analysis, function approximation, sampling and reconstruction theory, need to be established. In this talk, we will discuss these problems and introduce some of our recent achievements.

Title: Spatial-temporal brain structure change during the progression of Sporadic Alzheimer’s Disease
Speaker: Junjie Zhuo
Abstract: Identifying dynamic changes in biomarkers and clinical profiles is essential for understanding the progression of Alzheimer’s disease (AD). The relevant studies have primarily relied on patients with autosomal dominant AD; however, relevant studies in sporadic AD are poorly understood. By aligning normal cognition (CN) baseline with a clinical diagnosis of mild cognitive impairment (MCI) or sporadic AD, we studied the progression of AD using a linear mixed model to estimate the clinical and biomarker changes from stable CN to MCI to AD. Based on this research paradigm, we further studied the spatial-temporal brain structure change during the progression of Sporadic Alzheimer’s Disease.

Title: Reconstruction of brain-wide connectivity network at single neuron resolution
Speaker: Anan Li
Abstract: The brain is the most complex and significant organ, but little is known about brain function mechanisms yet. Despite the great efforts made by neuroscientists, our knowledge of the brain is still insufficient at the single neuron level. Micro-Optical Sectioning Tomography (MOST) has been developed to capture the characteristics of neurons across the entire mouse brain to meet this need. The huge amount of data collected during these brain-wide and single-neuron level studies has introduced challenges not seen in other fields. Among them, the key technologies of big data computing, image information extraction, and spatial positioning are particularly focused. This presentation will introduce how to build a complete data processing pipeline to achieve accurate, high-throughput, and automated computing based on MOST/fMOST mouse brain datasets.

Currently, Li is a professor of biomedical engineering at Wuhan National Laboratory for Optoelectronics (WNLO). He is conducting research activities in processing, analysis, and visualization of the TB-sized neural images collected by the Micro-Optical Sectioning Tomography (MOST). He has published more than 100 research papers in journals, such as Science, Nature Methods, Neuron, Neuroinformatics. He has received the following honors in China: second-place prize in State Technological Invention Award, National Excellent 100 Doctoral Dissertation, first-place prize in Hubei Provincial Award for Science and Technology Progress. He received funding from the NSFC for the Excellent Young Scientists Fund in 2021.
