Limbic system Flashcards
What is the limbic system involved in
emotional experience and visceral regulation
What structures are part of the limbic system
Cingulate gyrus Hippocampus and dentate gyrus parahippocampal gyrus Amygdala Hypothalamus anterior thalamic nuclei septal area
How do signals flow in the limbic system (roughly)
cingulate –> hippocampus, amygdala, septum –> hypothalamus –> thalamus
what is the hippocampal formation
hippocampus, dentate gyrus, parahippocampal gyrus, subiculum
What are hippocampal afferents (inputs)
contralateral hippocampus, adjacent inferior temporal cortex, brainstem nuclei
what are efferents of the hippocampus (outputs)
hypothalamus, anterior thalamus
what does the hypothalamus do
main integrator of autonomic and endocrine systems
participates in memory, experience of emotion and autonomic response to emotio
What are the inputs and outputs of the hypothalamus
input: hippocampus, visceral afferents, somatosensory afferents
outputs: anterior thalamus, vagal nuclei, sacral autonomic nucleus
What is declarative memory?
face and name memory
intact hippocampus required
What are the inputs and outputs of the amygdala
input: temporal and frontal cortex, septum and olfactory cortex, brain stem
output: hypothalamus, septum
