Medulla
Pons
Cerebellum
|
-flow of info between brain and sc
-connects 2 sides of cerebellum, integrates movement in R and L sides of body
-balance, posture, coordinated movement, smaller linked to autism, ataxia if damanged

Midbrain
|
Reticular Formation
Reticular Activating System
|
|
|
Reticular Formation
|
from SC into forebrain and affects REM Sleep, coughing, vomiting, has 90 nuclei
|
|
|
Reticular Activating System
|
in the RF and is vital to consciousness, arousal, wakefulness, damage = disrupted sleep-wake cycle
|
|
|
Thalamus
|
relay station, transmits all info except olfactory, motor movement, language memory
|
|
|
Korsakoff SYndrome
|
atropy of neurons in the dorsomedial nucleus of thalamus and mammillary bodies of hypothalamus
caused by thiamine deficiency via alcoholism
anterograde amnesia
|
|
|
Hypothalamus
|
hunger, thirst, sex, sleep, temp, emotional rxn, movement, maintain homeostasis
|
|
|
suprachiasmatic nucleus
|
in hypothalamus
mediates sleep-wake cycle
season affective d/o
|
|
|
basal ganglia
|
caudate nucleus, putamen, globus palladis, substantia nigra
planning, org, coord of motor movement
Huntington's, Parkinson's, Tourette's, mania, depression, OCD, psychosis
|
|
|
Limbic Sysem
|
Amygdala - attaches emotions to memories, recall of emotionally charged experiences
Hippocampus - learning and memory, processing visual and auditory info, Consolidation of declarative memories
|
|
|
Kluver-Bucy Syndrome
|
bilaterial lesions on amygdala, resulting in decreased fear and aggression, increased docility, hypersexuality
experiments with monkeys who then age meat
|
|
|
Removal of portions of hippocampus
|
tx for epilepsy
results in anterograde and retrograde amnesia

|
MOtor - voluntary movement
PRemotor - Broca's area, controls speech production
Prefrontal - complex bx like memory, exec fxn
