Blocking action potentials with TTX in the retinal ganglion cells of one eye has the same effect as monocular deprivation in development. This suggests that

Question

Quizplus · Accepted Answer

Blocking action potentials with TTX (tetrodotoxin) in retinal ganglion cells effectively silences neural activity from one eye, mimicking the effects of monocular deprivation during development. This demonstrates that ocular dominance patterns in the visual cortex are influenced by neural activity from the eyes, as the absence or reduction of activity from one eye can lead to changes in how visual cortical cells respond to inputs from both eyes.
