Schachter-Singer Two Factor Theory
Component’s of Broca’s Limbic Lobe
Cingulate gyrus Parahippocampal gyrus Subcallosal gyrus Isthmus Uncus
What are they two key phylogenic developments?
Atrophy of olfactory system
Expansion of the frontal and parietal lobes
Hippocampus-Thalamus-Mammillary Bodies: provide stimulus info to Cingulate gyrus
Hypothalamus mediates physiological arousal
Info from two networks converge at Cingulate gyrus and give rise to subjective emotion
Papez Circuit (1937)
Brought Septum and Amygdala into Papez’s circuit and argued system was automatic, proverbial, unconscious, and inaccessible to intellect
Paul Maclean (1949): “Visceral Brain”
Low road: fast way of getting low resolution visual info straight to Amygdala bypassing V1, “where” stream, bottom-up
High road: slow way of getting high resolution visual info to cortex, “what” stream, top-down
LeDoux (1998)
Symptoms for Kluver-Bucy Syndrome (Limbic System lesions)
Docility Loss of fear Hyperorality Hyperphagia Hypersexuality Psychic blindness Memory impairment Aphasia Utilization behaviors Seizures
What lesions in the limbic system can cause Kluver-Bucy Syndrome?
Bilateral glioma Head trauma Status epilepticus Herpes simplex encephalitis Post epilepsy surgery
Demonstrated that ventromedial frontal lobes play critical role in behavioral monitoring and emotion regulation
Phineas Gage
Trans orbital or “Icepick” Lobotomy
Walter Freeman
Symptoms of Temporal Lobe Epilepsy
Aura (deja-vu) Behavioral automatism (lip-smacking) Mood changes (anxiety, depression Attention/cognitive comorbities Ictal amnesia
