Neural Basis Of Emotions Flashcards
Two kinds of fear?
Innate, don’t need to experience it
Learned or conditioned from experience
What are the two sensory pathways used to create the emotion fear at the amygdala?
Direct thalamus to amygdala pathway that ends up in the lateral nucleus of the amygdala. Rapid response.
Indirect thalamus cortex amygdala pathway that ends up in the lateral nucleus of the amygdala. Slower response
What is the role of the lateral nucleus with fear?
Integrates the input from the two pathways with the experience and then sends the information to the basal and intercalated nuclei and then all the information ends up in the central nucleus of the amygdala.
What is the role of the hypothalamus with the emotion of fear?
Decides which physiological responses are now required
Anger is mediated through which structure and requires what?
Amygdala
Dopamine acting D2 receptors
What 3 structures are required to inhibit/suppress anger?
Neocortex
Ventromedial hypothalamic N
Septal Nuclei (produces pleasure)
What structure of the brain is strongly activated with the emotion sadness?
Lower sector of the anterior cingulate cortex
What part of the brain is associated with Disgust?
What disease to remember where we don’t have the ability to recognize/feel disgust?
Putamen
Huntington’s
Two parts of the anterior cingulate cortex?
Ventral - affective
Dorsal - cognitive
3 roles of the ventral anterior cingulate cortex in regards to emotion?
Integration of all emotion input
Regulation or control of the display of emotion
Monitors our current emotional state with ongoing newly presented information that can change our emotional state
What 4 places does the ventromedial prefrontal cortex receive emotion input from?
Amygdala
Hippocampus
Temporal visual association cortex
Dorsolateral prefrontal cortex
Three major roles of the ventromedial prefrontal cortex?
Reward processing
Integration of bodily signals, the gut feeling
Regulation of delaying gratification
