Cards

Term
function of the primary motor cortex
Definition
precise skeletal muscle movement
Term
function of the premotor cortex
Definition
learned motor skills
Term
function of broca's area
Definition
motor speech, only in left hemisphere
Term
function of frontal eye field
Definition
voluntary eye movements
Term
function of primary somatosensory cortex
Definition
receives sensory information & based on spatial discrimination-it identifies the region of the body being stimulated
Term
function of somatosensory association cortex
Definition
integrates sensory input
Term
function of visual area
Definition
receive's visual information from the retina
Term
function of auditory area
Definition
the primary auditory cortex receives sensory impulses from the inner ear (volume, pitch, location)
Term
function of olfactory cortex
Definition
smell receptors in nasal cavities send information to the olfactory area to bring awareness to odors
Term
function of gustatory cortex 
Definition
perceives taste stimuli
Term
function of visceral sensory area
Definition
think of visceral membrane that lines organs, therefore, this area senses visceral input like a full bladder or upset stomach
Term
function of vestibular cortex
Definition
spatial information from inner ear that is sent to the vestibular cortex to give awareness of balance and position in space
Term
function of multimodal association area
Definition
analyze, interpret, reason & verbalize (this is the region of our IQ)
Term
function of prefrontal cortex (anterior association area)
Definition
cognition, recall & personality
Term
function of posterior association area
Definition
recognize patterns, faces and location
Term
function of Wernicke's area
Definition
understand written words & spoken language
Term
function of Limbic Association Area
Definition
emotion impact
Term
function of basal nuclei
Definition
not fully understood, but is thought to play a role in sharpening motor skills, attention and cognition
Term
function of thalamus
Definition
relay station
Term
function of hypothalamus
Definition
important for maintaining homeostasis, emotional responses, sleep-wake cycles
Term
function of epithalamus
Definition
pineal gland which secretes melatonin to sleep
Term
function of corpora quadrigemina
Definition
visal and auditory reflexes (bypasses higher brain function)- when a harmful stimuli affects the body to effectively jump back
Term
function of substantia nigra
Definition
synthesizes dopamine precursor molecules
