What is Cerebellum, Describe It Terms in Brain Anatomy Flashcards

Balance and posture; sensorimotor learning and some other aspects of cognitive functioning

Vital to performance of coordinated and refined motor movements

Linked to Autism

Ataxia (slurred speech, severe tremors, loss of balance)

Respiration, coughing, vomiting, posture, locomotion, REM sleep

Part of reticular formation; consciousness, arousal, wakefulness; screens sensory input (esp. during sleep), arouses higher centers of brain when imp. info. must be processes

Disruption of sleep-wake cycle, can produce coma-like state of sleep

Subcortical and cortical structures

Thalamus, hypothalamus, basal ganglia, limbic system

"relay station," transmits incoming sensory information to the appropriate areas of the cortex for all senses except olfaction (that goes directly to amygdala); motor activity, language, memory

Thalamus, mammillary bodies of hypothalamus; thiamine deficiency, usually from alcoholism; severe anterograde amnesia, retrograde amnesia, confabulation

Hunger, thirst, sex, sleep, body temp, movement, emotional reactions, initiates responses needed to maintain homeostasis

Uncontrollable laughter, intense rage, aggression

Located in hypothalamus; mediates sleep-wake cycle and other circadian rhythms; maybe involved in seasonal affective disorder

Caudate nucleus, putamen, globus pallidus, substantia nigra
