Gray Et Al

Gray et al.(1989) studied synchronized neural oscillations while recording from two neurons,and they found that

A) the neurons responded with strongly synchronized neural oscillations when a single bar of light matching the neurons' preferred orientation moved across their receptive fields.
B) the neurons responded with strongly synchronized neural oscillations when two separate but aligned bars of light matching the neurons' preferred orientation moved across their recep- tive fields.
C) the neurons responded with strongly synchronized neural oscillations when two separate bars of light moved in opposite directions across their receptive fields.
