This working group serves users and use cases of MATLAB (and Simulink) for cellular-scale neuroscience, including electrical live recordings (e.g., neural probes), optical live recordings (e.g., calcium imaging), and anatomical imaging (e.g., connectomics). The working group is attuned to the associated data streams (e.g., behavioral data), computational methods (e.g., spike sorting, cellular source separation, neural simulation), and research resources/infrastructure (e.g., data archives, data standards). Cellular-scale neuroscience seeks to understand the function and structure of the central & peripheral nervous system at the levels of neurons & glia, including how they connect and interact as modules/networks at larger scales (aka systems neuroscience) and across select modules/networks distributed across the brain/body (the “mesoscale”).
