limbic system Flashcards
Sympathetic nervous system functions
fight or flight, expends energy
spinal cord origin of sympathetic nervous system
thoracolumbar
parasympathetic nervous system functions
rest and digest, preserves energy
digestion, heart rate, breathing
spinal cord origin of parasympathetic nervous system
craniosacral
function and location of hypothalamus
under the thalamus
control over autonomic nervous system and hormone secretion
functions of hippocampus
consolidation of memory, spatial memory
Hippocampus inputs/outputs
input from entorhinal cortex
outputs through fimbria to mammillary bodies/hypothalamus
hippocampus circuitry
functions of amygdala
fear, rage, aggression, sexual behavior
neurogenesis
new cells born in the dentate gyrus of the hippocampus throughout life
basolateral nuclei
inputs from hippocampus, association cortex, sensory cortex
outputs to medial prefrontal cortex, association cortex, ventral striatum
central nuclei
lower level sensory input
output to autonomic nervous system and modulatory systems
korsakoff syndrome
damage to mammillary bodies and limbic thalamus
amnesia, confabulation
toxoplasmosis
parasite in cat guts
infects rat amygdala and makes them not afraid of cats
kluver-bucy syndrome
bilateral lesions to medial temporal lobe
hyperphagia, hypersexuality, docility, amnesia
