Term
| Lateral Geniculate Nucleus |
|
Definition
| Goes through thalamus to the primary visual cortex, most optic nerves go thru |
|
|
Term
|
Definition
| Some optic nerves split and end here |
|
|
Term
|
Definition

|
|
Term
|
Definition
| Movement and patterns, most axons go to LGN |
|
|
Term
|
Definition
| Small ganglion cell bodies, have no clue what for, go to LGN, superior colliculus and thalamus |
|
|
Term
|
Definition
| V1/ Striated cortex. LGN comes here, then it goes out to V2 |
