In animals, electrical stimulation of the amygdala produces
behaviors associated with fear.
An agonist is a drug or other chemical that:
binds to a receptor site and triggers a response in the cell.
A particular neurotransmitter:
can have different effects, depending upon the receptor site to which it attaches.
The most common form of communication between neurons is:
chemical.
As a general rule, communication within a neuron progresses from the:
dendrites to the cell body to the axon.
Although disproved, phrenology was valuable in
generating interest in the idea of cortical localization.

neurotransmitter; receptor site
In synaptic transmission, the action potential stimulates the release of:
neurotransmitters by the synaptic vesicles.
The cell body of a neuron:
provides the energy needed for the neuron to function.
The brain's ability to physically change in response to environmental stimulation is called:
structural plasticity
Which part of the neuron receives messages from other neurons?
