Biological Psychology

Neurons

information processing cell of nervous system

Parts of Neurons

soma, dendrites, axon, terminal button

Gila Cells

supporting cell for neurons, supplying nutrients, provide myelin sheath

Myelin Sheath

speeds up message from neuron

Action Potential

electrical current carried down the axon, charge at rest -70mv,

Inter-neuron Communication

Synapse, transmission across synapse: neurotransmitter

somatic

afferent/sensory, efferent/motor

autonomic

sympathetic, parasympathetic

cerebellum

smoothness to movement(balanced walking)

Medulla

regulating unconscious functions

Pons

responsible for sleep and arousal

Reticular Formation

filters information, carries simulation related to sleep and arousal

Limbic System

hypothalamus, amygdala, hippocampus, thalamus

Hypothalamus

regulates basic needs(thirst, hunger, temp control)

amygdala

part of limbic system involved in emotion and aggression

hippocampus

part of limbic system used for learning and memory

thalamus

really center for cortex: incoming/outgoing signals

Cerebrum

responsible for, sensing, thinking, learning, emotion, consciousness, and voluntary movement
