Glutamate functions as the major inhibitory neurotransmitter in the brain.

If the human brain didn't have so many deep crevices and wrinkles in the cortex, then:

As a critical thinker in psychology, it is important to recognize that:

A brain without a peripheral nervous system would be like a radio without a receiver. Explain what is meant by this analogy.

The serotonin transporter is a neuromodulator that removes neurotransmitter from the synaptic cleft.
