L20 Flashcards
1
Q
Sub-cortical visual pathway
A
L-glutamate
eye specific laminae in the dLGN, and ON/OFF sub-laminae
lamination happens without the eye opening so is not sensory dependent
BUT blocked by injection of TTX into dLGN so is activity dependent
2
Q
Retinal waves during development
A
Stage I (prior to synaptogenesis) - right to left, FAST
Stage II (early synaptogenesis) - moves out from middle
Stage III (late synaptogenesis) - quick flash
3
Q
retinal waves (info)
A
established prior to eye opening
involving NMDA-R activation
