Kosslyn's transcranial magnetic stimulation experiment on brain activation that occurs in response to imagery found that the brain activity in the visual cortex

Involved in the perception and imagery

Explanation:

Transcranial magnetic stimulation (TMS) is the technique developed in 1985 used to stimulate the brain of humans.

The TMS produces the electric currents of the same frequency as generated during the vision, hearing and any other process. Thus, the technique is used to understand the functioning of the brain.

The visual cortex is the region of the brain which receives and processes the information from the retina and allows us to see therefore the studies through the technique enables us to establish the fact that the visual cortex is responsible for vision.

Thus, Involved in the perception and imagery is the correct answer.
