In the Context of Neural Basis of Perceptual Grouping, Gray

question 37

Multiple Choice

In the context of neural basis of perceptual grouping, Gray et al. (1989) studied synchronized neural oscillations by recording the responses of pairs of neurons with the same orientation preference in the primary visual cortex of an anesthetized cat. The results showed that:

• A) the neural oscillations were strongly synchronized when both receptive fields were stimulated by a single long bar.
• B) there was no synchronization of the neural oscillations when two separate bars of light moved in the same direction across receptive fields.
• C) the neural oscillations were strongly synchronized when two separate bars of light moved in opposite directions across receptive fields.
• D) there was no synchronization of the neural oscillations when both receptive fields were stimulated either with a single bar or with two separate bars.
