concerned with links between biology and behavior
receives/conducts messages/impulses (neuron).
extension, through which messages are sent (neuron).
regulates speed/protects (neuron).
neural impulse, electrical charge
stimulation (level) to trigger impulse.
gaps between two neurons (dendrites).
chemical messengers, between synapses, and bind.
neurotransmitter, trigger muscle contraction
neurotransmitters, linked to pain control and pleasure.
nerve cells of PNS and CNS
Central nervous system
brain and spinal chord.
Peripheral nervous system
sensory/motor neurons, connect to CNS.
connect CNS w/ muscles/glands/sense organs.
information from sense receptors to CNS.
communicate/intervene b/w sensory/motor inputs
information from CNS to muscles/glands.
Somatic nervous system
division of PNS controls skeletal muscle.
Autonomic nervous system
PNS controls glands/muscles (internal organs).
Sympathetic nervous system
division of ANS, arouses, mobilizing.
Parasympathetic nervous system
division of ANS, calms, conserves
response to sensory stimulus.
interconnected neural cells, learn, "muscle memory".
recording of electrical activity in the brain.
CT (computed tomography) scan
series X-rays, combined = slice through body.
PET (positron emission tomography) scans
display brain activity, radioactive glucose.
MRI (magnetic resonance imaging
magnetic fields/radio waves, distinguishes different soft-tissue.
automatic survival functions, central core of brain.
heartbeat/breathing, base of brainstem
nerve network, brainstem, controlling arousal.
sensory switchboard, directs/replies to messages.
emotions/drives, includes hippocampus/amygdala/hypothalamus
neural clusters, emotion
eating/drinking/temperature governs endocrine system via pituitary, emotion.
support, nourish, and protect neurons (aren't neurons).
speaking/muscle movements, making plans/judgments.
cerebral cortex, top, sensory cortex.
cerebral cortex, back, visual
above ears, auditory
rear frontal lobe, voluntary movements
front parietal lobes, registers/processes body sensations
higher mental functions (leering/speaking), cerebral cortex.
language impairment (Broca's/Wernicke's area).
muscle movement involved in speech.
brain's capacity for modification.
neural fibers, connecting hemispheres, messages between.
two hemispheres isolates (cut connecting fibers).
"slow" communication system, glands/hormones/blood stream.
chemical messengers, manufactured by endocrine glands, produced one tissue to another.
, above kidneys, secret adrenaline/noradrenaline.
endocrine, influenced by hypothalamus, regulates growth/endocrine glands.
