This auditory structure resembles a snail and is named after the Greek word for "land snail."
What is the Cochlea?
The scientific study of the nervous system.
What is Neuroscience?
The central nervous system (CNS) is composed of two divisions.
What is the spinal cord and brain?
Part of a neuron that is sometimes myelinated.
What is the Axon?
Transports three Na+ ions out of a cell for every 2 K+ ions transported in.

What is the Absolute Refractory Period?
Neurons that fire in response to making a particular movement or observing someone else making the movement.
What are Mirror Neurons?
Is the subdiscipline of biopsychology that is identified with the measurement of scalp electroencephalogram (EEG) activity and autonomic nervous system (ANS) activity in humans?
What is Psychophysiology?
This part of the brain regulates reflex activities critical for survival.
What is the Brain Stem?
Neurons with one axon and several dendrites emanating from the soma.
What are multipolar neurons?
The principle "that action potentials occur fully or not at all."
What is the All-or-None Principle?
These skin receptors are thought to mediate the perception of temperature change.
What are Free Nerve Endings?
A deficiency in the awareness of parts of one's own body.

A change in the resting potential of a postsynaptic dendrite from -70 mV to -72 mV is called.
What is an IPSP? (will also accept hyperpolarization)
Concerned with how the brain combines individual sensory attributes to form an integrated perception.
