Cortical layer basics:

layer 1: fibers (intracortical)

layer 2: cells receive from cortex

layer 3: cells project subcortically and intracortically

layer 4: cells receive from VPL thalamus

layer 5: cells project to spinal cord and subcortically

layer 6: cells project to spinal cord and subcortically
