V1 small scale• Basic properties– 6 layers I-VI (“gray matter”)• 100,000 neurons under 1 sq mm of cortex– cortical thickness, ~2 to 4mm• Layer IV receives LGN outputs– Apart from those neurons that LGN neurons form synapses with, V1neurons have the following properties (macaque):• spatial frequency selective (i.e. scale or size)• orientation selective• binocularity• motion direction selective• non-oriented cells, wavelength selective– Receptive fields properties modifiable by early visual experience• many computational neural models of self-organizationWednesday, August 29, 12
