L7- limbic system Flashcards
what is emotion
combo of psy and physio responses to a stimuli
why is emotion important
- communication with ppl
- behavioural
- aids memory - relating experience with emotion
- face - big part of the motor cortex
emotion can be ..?
+ve - approach behaviour
-ve = avoidance behaviour
system in the brain involved in behaviour and emotions
limbic system
what is papex circuit
limbic circuit connecting parts of the brain involved in the emotional component
components in the papez circuit
neocortex >< cingulate gyrus
cingulate gyrus>hippocampus>hypothalamus> anterior thalamic nuclei > cingulate nuclei
role of amygdala
processing fearful and threatening stimuli
- found in the temporal lobe
pathway of fearful stimuli
stimuli>sensory cortex> hypothalamus> ANS, PAG> behavioural response> cortex> emotional experience
controlling factors for aggression
amygdala, hypothalamus
components in revised papez circuit
amgyadala added
signs of dysfunctional amygdala
anxiety, depression, autism, aggression
treatments for emotional disorders
- manipulation of circuitry
- removal of frontal lob e- no effect on intelligence
- deep brain stimulatoin
- drugs?
