M and P Retinal Ganglion Cells
RG Cells are not just light detectors.
- Cells classified by what "turns them on"
- receptive field properties of cells
M cells
a) project to Magnocellular layers of LGN
b) dominant in DORSAL/WHERE stream
c) also go to SC
d) fast conducting, colorblind, low acuity
P cells
a) project to Parvocellular layers of LGN
b) dominant in VENTRAL/WHAT stream
c) slow, color selective, high acuity
