|
precentral gyrus
|
primary motor area
frontal cortex telecephalon -- forebrain |
|
|
postcentral gyrus
|
primary somatic sensory area (body senses)
in parietal cortex telecephalon -- forebrain |
|
|
prefrontal cortex
|
integration of motor activity
in frontal cortex Telecephalon --> forebrain |
|
|
basal ganglia
|
includes globus pallidus, putamen and caudate nucleus
motor functions (this area is mainly inhibitory to other motor regions in the brain (does some fine tuning) telecephalon --> forebrain |
|
|
limbic system
|
includes amygdala, hippocampus, fornix arch, mammilary bodies & nucleus accumbens
|
|
|
amygdala
|
judgment for reward/punishment, aggressive behaviors, reproductive behaviors inhibits the performance of defense behaviors
in limbic system of diencephalon --> forebrain |
|
|
hippocampus
|
spatial orientation, memory (particularly consolidation), controls cortisol secretion
in limbic system of diencephalon --> forebrain |
|
|
fornix arch
|
connects hippocampus with other brain parts
in limbic system of diencephalon --> forebrain |
|
|
mammilary bodies (breast shaped)
|
connect & contains part of hypothalamus
in limbic system of diencephalon --> forebrain |
|
|
nucleus accumbens
|
gate or filter for sensory info & memory related to reward acquisition.
in limbic system of diencephalon --> forebrain |
|
|
thalamus
|
relay system: receives & routes all sensory & motor info
in ldiencephalon --> forebrain |
|
|
hypothalamus
|
THE REGULATOR: organizes behaviors critical to survival of the species.
controls autonomic NS, endocrine system (pituitary). affects eating & satiety, water metabolism fight/flight behaviors, SNS sexual/reproductive activities in diencephalon --> forebrain |
|
|
suprachaismic nucleus
|
master clock of the body (responds to light), temperature cycle (circadian rhythms), sleep/wake cycle.
in hypothalamus of diencephalon --> forebrain |
|
|
pineal gland
|
modulates light/dark rhythms (via melatonin).
in diencephalon --> forebrain |
|
|
substantia nigra
|
fine tuning of motor movements projects to basal ganglia (caudate)
primary site of dopamine synthesis in tegmentum of midbrain |
|
|
raphe nucleus
|
sleep/wake, arousal, eating/satiety, moods
primary site of serotonin synthesis in pons of metencephalon --> hindbrain |
|
|
locus coerleus
|
sleep/wake, arousal, part of RAS, moods
primary site of norepinephrine synthesis in pons of metencephalon --> hindbrain |
|
|
area posterema
|
visceral response, outside BBB
in pons of metencephalon --> hindbrain |
|
|
medulla
|
vegetative functions: cardiorespiratory, swallowing, vomiting, skeletal muscle tonus
in myelencephalon of hindbrain |
|
|
solitary nucleus
|
heat, fullness (gustatory), motion
in medulla of myelencephalon of hindbrain |
