Neurophys of Emotion (Karius) Flashcards
(17 cards)
Emotional fx of hypothalamus
Used to create physiologic response to emotion
Emotional fx of olfactory cortex
Odors provide strong stimulus for emotion
Emotional fx of thalamus
Relays sensory info into system
Emotional fx of basal ganglia
Pleasure, disgust
Emotional fx of hippocampus
Links emotion to memory creation. Surrounded by regions related to surprise
Emotional fx of amygdala
Strongly linked with fear/anger
Emotional fx of cingulate cortex
Higher level control and sadness
Input pathways for fear
Rapid response- Direct thalamo-amygdaloid pathway
Later reponse- Indirect thalamo-cortico-amygdaloid pathway
Pathway for fear
Lateral nucleus of amygdala - intercalated and basal nuclei - central nucleus of amygdala - appropriate parts of limbic system
What brain region is anger associated with?
Amygdala
What is anger suppressed by?
Neocortical, septal, hypothalamic influences
What brain regions is/are avoidance associated with?
Entorhinal cortex, dorsal midbrain, lateral posterior hypothalamus
What brain region is sadness associated with?
Lower sector of cingulate cortex
What brain region is disgust associated with?
Putamen and insular cortex (Associated w/ Huntington’s Disease)
What brain region is suprise associated with?
Parahippocampal gyrus
What is anterior cingulate cortex’s (ventral region) role in higher order emotional processing?
- Integrates all sensory/emotional processing
- Controls emotional display
- Conflict detection
What is prefrontal cortex (ventromedial subdivision)’s role in higher order emotional processing?
- Reward processing
- Gut-feeling
- Delayed gratification
