Question 4

The critical period for amblyopia treatment is primarily defined by:

Accepted Answer

Neural plasticity of the visual cortex

Answer

The critical period for amblyopia treatment is defined by the period of neural plasticity in the visual cortex during which visual development can be influenced.
