diencephalon - Coggle Diagram
diencephalon
externally in the basal view of the brain
mammillary bodies
tuber cinereum
median eminence
hypophysis
optic chiasm
anterior perforated body
posterior perforate bodies
functional anatomy of the hypothalamus
regulation fo temperature and reproductive functions
regulation of circadian rhythms.
stimulation and inhibition of the appetite
regulation of the autonomic nervous system
regulatoon of the pituitary gland
the hypothalamus is divided in:
preoptic region
supraotpic region
tuberai region
mammillare region
deep diencephalic structures
thalamus
anterior tubercle
internal medullary lamina
pulvinar
lateral geniculate body (visual)
medial geniculate body (acoustic)
interthalamic adhesion
laterally delimited by the internal capsule
hypothalamus
periventricular hypothalamus
subthalamic hypothalamus
motor function (nuclei of the visceral motor neurons)
functional anatomy of the thalamus
display the 3rd neurons of the sensitive pathways
anterior group
receive from: hippocampus, hypothalamus and mammillary bodies
project: cingulate cortex→ limbic circuit
allow the integration of emotional control
medial group
mediodorsal nuclei
receive form: basal ganglia, amyloid body, olfactory cortex
project: prefrontal cortex
control the behavior
lateral group
lateral dorsal nuclei
perception and integration of emotional states
lateral posterior nuclei
receive from: superior optic colliculi
project: parieto-occipital cortex
visual reflex and focus fixation
pulvinar
superior optic colliculu
parieto occipital cortex and temporal lobe
visual reflexes and focus fixation
ventral posterolateral nuclei
receive sensory info from the body pars below the neck
ventral posteromedial
receive sensory info of the fave and gustatory stimuli
ventral anterior and ventral lateral nuclei
from: basal ganglia, substantia nigra
project to: motor and premotor cortex.
allow the elaboration and inhibition of the motor command (
cortex-basal ganglia-thalamus-cortex path
).
geniculate bodies
acoustic and visual info
project to the occipital and temporal cortices.
