3 types of neurons
motor (efferent), interneurons, sensory (afferent)
parasympathetic response
rest-and-digest; constricts pupils, bronchi, bladder; stimulates saliva, peristalsis, bile; slows heartbeat
sympathetic
fight-or-flight; dilates pupils, inhibits saliva, relaxes bronchi, accelerates heartbeat; piloerection or sweating; stimulates glucose production, adrenaline ad noradrenaline, orgasm
hindbrain
cerebellum, medulla oblongata, reticular formation
midbrain
inferior and superior colliculi
forebrain
thalamus, hypothalamus, basal ganglia, limbic system, cerebral cortex
parts of forebrain: thalamus
relay station for sensory info
parts of forebrain: hypothalamus
maintains homeostasis, integrates endocrine system through hophyseal portal system through anterior pituitary
basal ganglia
smoothens movements, maintains postural stability
limbic system
controls emotion and memory, including septal nuclei (pleasure-seeking), amygdala (fear and aggression), hippocampus (memory), and fornix (communication within the limbic system)
cerebral cortex - frontal
executive function, impulse control, long-term planning (prefrontal cortex), motor function (primary motor cortex), speech production (Broca’s area)
cerebral cortex - parietal
sensation of touch, pressure, temp, pain (somatosensory cortex); spacial processing, orientation, and manipulation
cerebral cortex - occipital
visual processing
cerebral cortex - temporal
sound processing (auditory cortex), speech perception (Wernicke’s area), memory, and emotion (limbic system)
acetylcholine
voluntary muscle control, parasympathetic nervous system, attention, alertness
epinephrine and norepinephrine
fight-or-flight responses, wakefulness, alertness
dopamine
smooth movements, postural stability
serotonin
mood, sleep, eating, dreaming
GABA, glycine
brain stabilization
glutamate
brain excitation
endorphins
natural painkiller
sensation
conversion of physical stimuli into neurological signals
perception
processing of sensory information
sensory receptors
respond to stimuli and trigger electrical signals
