Statistics and Geometry of Neuronal Connections

Explore the statistics and geometry of cortical connections, including long-range axonal connections, micro-circuits, and the mini-architecture of the cerebral cortex. Topics include functional and anatomical connectivity, species comparison, spatial levels of connectivity, and neural plasticity.

  1. 18th May, Morning Session IStatistics and geometry of neuronal connections Chair: Noritaka Ichinohe Lab for Cortical Organization and Systematics Brain Science Institute, RIKEN Questions The statistics of the cortical connections: long-range axonal connections and micro-circuits The mini-architecture of the cerebral cortex. The on-board micro-circuitry, dendritic growth, trees bifurcations (development of connectivity) and plasticity
