Chapter 2 Flashcards
biological psychology
concerned with the links between biology and behavior
threshold
level of stimulation required to trigger a neural impulse
sensory neurons
sends info from the bodies tissue and sensory organs to the central nervous system
interneurons
internally communicate and intervene between sensory inputs and motor outputs
motor neurons
controls the muscles
somatic nervous system
controls voluntary movements of skeletal muscles
autonomic nervous system
controls self regulated action of internal organs and glands
neural networks
interconnected neural cells
EEG
An amplified readout of waves
PET scan
depicts brain activity by showing each brain areas consumption of chemical fuel
medulla
where the spinal cord enters the skull and swells slightly
motor cortex
controls voluntary movements
sensory cortex
registers and processes body touch and movements sensations
Association Areas
areas of the cerebral cortex not involved in primary motor or sensory functions
cerrebelum
involves movements
hippocampus
memory
amygdala
detects fear and plans for emergencies
parasympathetic nervous system
calms you down
back of brain
vision
brainstem
relays signals from brain to spinal cord
axon
extension of neuron, send impulses away from the cell
axon terminal
continues a signal from the axon to the neuron or tissue
dendrite
collect input from other nerve cells
Frontal lobe
Risk vs reward, speaking, decision making, social ability
