Corticolimbic System Flashcards
Describe the anatomical components of the limbic system and their major interconnections
Describe the inputs to the amygdala
Olfaction
Thalamus (low road)
Sensory cortices (high road)
Insula
Explain the major functions of the insular cortex and relate these to its anatomical
subdivisions
insula = primary interoceptive cortex
Posterior (least complex)
Mid-insula
Anterior insula (most complex)
Detail the basic input/output relationships of the amygdala complex and the
functional specializations of its major nuclei
Explain the role played by the bed nucleus of the stria terminalis in chronic anxiety
Summarize how interoception and visceromotor control support allostasis
Explain the theory of constructed emotion
Correlate limbic anatomical structures with their involvement in common disorders
of the corticolimbic system: autism, panic attack, major depressive disorder, PTSD, and chronic anxiety
Spooky Case: Explain how the Toxoplasma parasite alters host behavior to increase predation risk by cats
Name the three amygdala Nuclei
Basal and lateral (BLA)
Central (CeA)
Medial
Name the symptoms of Kluver-Bucy Syndrome
Psychic blindness Hypersexuality Lack of fear Hyperorality Memory and learning deficits
what makes up the rostral components of the limbic system?
Anterior Cingulate Cortex (ACC) Subgenual ACC (sgACC) Olfactory system Amygdala Insula
What are the two broad components of the Corticolimbic system?
Rostral and Caudal
What is the function of the Rostral Limbic system?
Construction of emotion
What is the function of the Caudal limbic system
Memory and visuospatial function
