Area 17
Primary Visual Cortex
6 layers
LGN
large cells;
eceive information about movement and contrast from M-cells
Magnocellular layers
1 and 2 of LGN
•Magnocellular layers
Parvocellular layers
small cells;
receive information about form and color from P-cell
3-6 of LGN
Parvocellular layers
Optic tract fibers are segregated by eye in the
LGN
--- LGN layers receive fibers from the ------ eye and --- layers receive fibers from the ------ eye
Three LGN layers receive fibers from the contralateral eye and 3 layers receive fibers from the ipsilateral eye
the upper visual field contribute to the ---- optic radiations, and terminate in the ---- aspect of V1
the upper visual field contribute to the inferior optic radiations, and terminate in the inferior aspect of V1
calvarian fissure
separates upper and lower visual field of V1
