lecture 3: nervous system
periphere
autonomic
parasympathic
rest & digest
sympathic
active & alert
somatic
voluntary skeletal muscles
central
spinal cord
brain
mesencephalon
midbrain
defense system
aggression, defense, reproduction patterns
Periaqueductal gray
arousal system
Regulating wakefulness/sleep, Motor control, posture
Locus coereleus: norepinephrin
Midbrain raphe nuclei: serotonin
rhombencephalon
metenchephalon
cerebellum
very high neuron density (~80%)
First evolutionary step towards guided action
forward models (anticipates movement outcomes)
pons
bladder control, eye movement, facial expression, equilibrium and posture
connects the cerebellum and the cerebral cortex
myelencephalon
medulla
Vestibulo-cochleaire reflex (VCR)
Vestibulo-oculaire reflex (VOR)
breathing, heart rate, reflexes
procephalon
telencephalon
cerebrum
diencephalon
hypo thalamus
homeostasis + basic drives
Hormone secretion through the pituitary gland
thalamus
sensory + motor relay to cortex
relay nuclei
Pulvinar (taking input from the superior colliculus) projects to parietal cortex
Lateral Geniculate Nucleus LGN: pathway from eyes to visual cortex
Intralaminar nuclei
diffuse cortical activation (wakefulness/consciousness)
Reticular nucleus
modulates thalamic activity (gating, coordination)
