Question

A PET scan of a patient looking at a photograph of a painting would most likely indicate high levels of activity in which brain structure?

a. sensory cortex
b. Broca's area
c. corpus callosum
d. occipital lobes
e. frontal lobes

Answer 1

High levels of activity in response to visual stimuli like looking at a photograph of a painting would most likely be detected in the occipital lobes of the brain, which are responsible for primary visual perception. Option d is correct.

Step-by-step explanation:

A PET scan of a patient looking at a photograph of a painting would most likely indicate high levels of activity in the occipital lobes. The occipital lobes are located at the back of the brain and are primarily responsible for processing visual information. This is supported by Brodmann's areas 17 and 18, which are located in the occipital lobe and responsible for primary visual perception.

Visual information is complex and requires additional processing in other lobes, but the initial perception and processing occur here. Hence, when looking at a photograph, the most active brain structure would be the occipital lobes
