|
Diencephalon |
Epithalamus, Thalamus, Hypothalamus |
|
|
Thalamus |
gateway to cerebral cortex; specific thalamic nuclei, nonspecific thalamic nuclei, and lateral geniculate nerve most sensory info goes first to thalamus then cerebral cortex transports sensory and motor info from cerebral cortex to other systems and from other systems to cerebral cortex |
|
|
Hypothalamus |
pituitary gland- hormones |
|
|
Telencephalon |
basal ganglia, olfactory system, hippocampus, amygdala, cerebral cortex |
|
|
basal ganglia |
caudate, putamen, globus pallidus movement in general connections most abundant w/frontal areas of cortex: planning behavior,memory,emotional expression |
|
|
sulcus/gyrus |
outside groove/ inside hill (folds and bumps in cerebral cortex) |
|
|
Lobes of cerebral cortex |
frontal, parietal, occipital, temporal, limbic(inside under others) |
|
|
limbic system |
olfactory bulb, hypothalamus, amygdala, cingulate gyrus forms a border around the brainstem important for motivations/emotions such as eating, drinking, sex, anxiety, aggression |
|
|
basal forebrain |
nucleus basalis-> arousal, wakefulness, attention deterioration-> Impairments of intellect, attention |
|
|
Ventricles |
4 fluid filled cavities; cells called "choroid plexus" make cerebrospinal fluid(csf) which fills the ventricles meninges- membrane surrounding brain acts as cushion upon impact hydrocephalus- associated w/retardation, csf builds up in ventricles and creates pressure on brain |
|
|
occipital lobe |
main target for visual info, posterior pole known as primary visual cortex destruction causes cortical blindness in responding part of visual field-> no pattern perception |
|
|
parietal lobe |
post central gyrus- (primary somatosensory cortex) main target for touch sensation four bands of cells: 2 receive light touch info, one receives deep pressure, other receives combo of both monitors info about orientation of eyes, head etc, so you know where stuff is |
|
|
Temporal lobe |
primary cortical target for auditory info essential for understanding spoken language(often left lobe) aspects of vision: perception of movement, facial recognition damage results in kluver-bucy syndrome: doesn't show normal fears |
|
|
frontal lobe |
Contains primary motor cortex and prefrontal cortex prefrontal cortex: receives info from all sensory systems, important for working memory, and behaviors that are context dependent precentral gyrus- specialized for small movements |
|
|
binding problem |
perceive to sensations as happening at the same time/place |
