Question 7

In the context of neural plasticity, what happens in the somatosensory cortex after a finger is amputated?

Accepted Answer

The area is reassigned to other fingers

Question 8

Which class of drugs is used to treat depression by increasing the time serotonin remains in the synaptic cleft?

Accepted Answer

Selective Serotonin Reuptake Inhibitors (SSRIs)

Question 9

Which brain structure connects the left and right cerebral hemispheres, allowing communication between them?

Accepted Answer

Corpus callosum

Question 10

A split-brain patient sees a word in the left visual field. What is the most likely outcome?
