Neuropychology Of Emotion

Question 1

Neruoranatomy pf emotion in the limbic system

Answer 1

Emotions are a result of network of direct and trans-synaptic connections

No single limbic system
But rather network of connections

Question 2

Appraisal occurs in

Answer 2

Orbitofrontal cortex

Amygdala

Question 3

Orbitofrontal cortex: appraisal

Answer 3

Input: ventral cortical streams- a pathway that carries visual information from the primary visual cortex to the temporal lobe
This is identity

Medial: reward
Activated by subjective pleasantness

Lateral: punishment/ non reward
Negative reward prediction error
Expectation of punishment

Output: carried out by anterior cingulate

Question 4

Amygdala: appraisal

Answer 4

Older brain: overshadowed by OFC

Conditioned responses to harmful stimuli

Facial expression regulation

Little involved in subjective emotional experience

Slower response in reversal learning tasks

Question 5

Cingulate cortex- action outcome learning

Answer 5

Anterior: outcome
• Supracallosal: punishment/non-reward data from lateral OFC
• Pregenual: reward signals from medial OFC

Posterior: action
• Input from parietal lobes (spatial/action
related information)
• Output: hippocampus

Mid: action
• Output to premotor areas (eg SMA)

Question 6

Ventral medial prefrontal cortex: reward- related decision-making

Answer 6

Synaptic networks signal value of chosen offer

Question 7

Autonomic responses

Answer 7

Modulated by:
-OFC via anteroventral insula and
subgenual cingulate cortex
-Amygdala
• Hypothalamus
• Periaqueductal grey

Feedback from autonomic output not needed for emotional behavior/feelings
