Electrical Recordings in the Visual Cortex Indicate That Years After

Electrical recordings in the visual cortex indicate that years after monocular deprivation in monkeys,

A) no ocular dominance columns were established; most cortical neurons responded equally to both eyes.
B) most cortical neurons responded to stimulation of the non-deprived eye, with very few responding exclusively to the previously closed eye.
C) a normal number of cortical neurons responded to stimulation of the previously-closed eye, but the response patterns were disorganized.
D) the structure and response patterns of cortical neurons were similar to those of un-deprived animals.
E) the retina of the deprived eye was still unable to respond to stimulation by light.
