Mirror neuron system:
Neurons light up when one observes an action, as well as when imitating or being imitated
Amygdala activation is greater with what types of emotion?
Negative
What causes Urbach Wiethe disease?
Calcification of amygdala
Signs of Urbach Wiethe disease?
- Loss of facial expression or fear
- Loss of recognition of facial expressions of fear
- Normal expression and recognition of other emotions
Pertaining to fear, amygdala is not involved in ____
Generating fearful responses
Gaze tracking:
Tracking another person’s gaze in situations that are ambiguous or uncertain
Medial prefrontal lobes include portions of:
The orbitofrontal cortex and cingulate cortex
Whole brain theories of emotion:
Right hemisphere model & valence model
Right hemisphere model of emotion:
Right hemisphere is dominant for emotions, perception, expression, and experience
Valence model of emotion:
Right hemisphere dominant for negative emotions, left for positive
Brain areas theories:
Lateralization of particular structures and emotions
Emotional processing in ASD:
- Impaired recognition of facial emotions
- Difficulty interpreting emotions
- Reduced attention to social stimuli
- Difficulty assessing appropriateness of social interactions
Brain imaging studies of ASD:
- Low activation of fusiform face area to faces
- Low activation of amygdala to facial emotions
- Low activation of mirror neurons
- Low coordination of PFC with other areas
Cingulate cortex differences in brain activity of psychopaths:
Decreased responsiveness and connectivity
Insula differences in brain activity of psychopaths:
Decreased activity
