1. Session I Statistics 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 18th May, Morning

2. Topics 1. Bringing together functional and anatomical connectivity 2. Species comparison and bridging (human, monkey, rodent) 1. McIntosh 2. Van Essen

3. 1. McIntosh 2. Van Essen (macroscopic area to area connectivity) 3. Rockland (long-range+local circuit) 4. Silberberg (local circuit) 3.
