AP Psychological Biological Perspectives Unit

Known as the "Little Brain" and is in charge of balance and coordinating movements

• Thalamus
• Reticular Formation
• Hypothalamus
• Cerebellum

Damage this and you won't form new memories

• Hypothalamus
• Hippocampus
• Amygdala
• Thalamus

This releases neurotransmitters which are sent into the synaptic cleft for receptors on the dendrite to taste

• axon
• axon terminal
• gene
• neuron

A network of branches coming from individual cells.  They carry information and electrical signals in the brain and nervous system

• axon
• axon terminal
• dendrite
• neuron

This insulating material forms a layer, around the axon of a neuron.  It enables electrical signals to travel down the axon at higher speeds.

• neuron
• myelin sheath
• dendrite
• neurotransmitter

A chemical produced by neurons that carries messages to other neurons

• myelin sheath
• neurotransmitter
• axon
• axon terminal

The tiny gap between neurons where nerve impulses are sent from one neuron to another.  It is where communication occurs between an axon and dendrite

• synapse
• axon terminal
• impulse
• myelin

Provides insulation and protection to prevent interference from other electrical signals; also play a role in learning, thinking, and memory

• Glial Cells

• Schwann cells

When a neuron is not engaged in an impulse.

• Resting potential
• Action potential
• Neural potential
• Synaptic potential

Describes the fact that a neuron fires at the same intensity despite the intensity of the stimulus.

• Threshold
• Repolarization
• All or None Principle
• Action Potential
