Somatosensory Development of Whisker Barrels in Rodents Is Similar to Visual

Multiple Choice

Somatosensory development of whisker barrels in rodents is similar to visual development of ocular dominance in this way.

A) Both have a critical period for plasticity that is experience dependent and relies on GABAergic inhibition.
B) Both have a critical period for plasticity that relies on NMDA receptor activity and is unaffected by TTX.
C) Both develop normally with partial sensory input (e.g. some whiskers are trimmed, one eye is closed) , but do not develop normally in the complete absence of sensory input.
D) Both are established prior to birth and rely on spontaneous activity prior to any sensory experience.
E) Both are established prior to birth and can develop normally without sensory experience or spontaneous neural activity.
