1. Allows for binocularism 2. Cells in 4C have a circular receptive field, but cells outside layer 4C have elongated receptive fields that respond best to bars or edges of light. 3. 1,4,6 => contralateral; 2,35 ipselateral 4. M cells => magno cells; non color specific; detects for dynamic form (motion); larger receptive field. Synapses in 4C alpha, which goes to layer 4A and 4B, which then form two types of complex orientation selective cells: those with directional selectivity and

Unformatted text preview: nondirectional selectivity a. P-cells => parvo cells; color specific; detects for color; smaller receptive field (sees the finer details). Synapse in 4C beta, which synapses to layers 2 and 3. 5. Cells a. Simple Cells i. Respond weakly to small flashes of light ii. Orientation specificity b. Complex i.
