brain; spinal cord

In the brain's medial-lateral axis, the medial position refers to __ inside the skull.

deep

The __ is the site of neurotransmitter release that determines postsynaptic response.

synapse

The molecular approach to biopsychology involves studying changes to the ________ or ______ and how they influence neural activity

neurochemical environment, gene expression

Interneurons primarily function to __ the rate of information spread in neural circuits.

control

head-twitches

The __ cortex corresponds to the neocortical somatosensory area responsive to individual whiskers.

barrel

Dendritic __ are responsible for the integration of inputs into neurons.

spines

Neuroplasticity involves changes in the connections between __ rather than the number of neurons.
