Can conduct bioelectric signals for long distances without any loss of signal strength.
They possess synapses.
They have plasticity.
Provide support and insulation for neurons. More than 10x the amount of neurons. Are both macro and micro.
These are involved in immune function within the brain. Act as scavengers to remove dying cells at the site of damage.
These provide support and insulation; also accumulate glucose and synthesize glycogen; take up excess neurochemicals.
Change in potential toward a more polarized state (more negative state, or AWAY from zero).
A change in membrane potential propagated down an axon that is the basis for rapid transmission of information.
The wide portion of the axon adjacent the soma where action potential is initially generated.
Includes the cerebellum (movement/balance), pons (alerness, locus coeruleus, and raphe nuclei), and the reticular formation (arousal/attention/sleep).
Includes the thalamus (sensory/motor info) and the hypothalamus (SNS, motivated behavior).
Includes the neocortex (cerebral cortex), basal ganglia (modulates movement), and limbic system (mood, emotions, learning, memory)
