What are the five different circuits?
Emotion Goal-Directed behavior Social behavior Oculomotor Motor
Emotion Circuit - controls?
Mood
- Links emotion to motivation and action
- Rewarding seeking behaviors
- Emotion/facial expressions
Emotion Circuit - participates in the perception and experience of?
emotion
Emotion Circuit - makes predictions when outcomes uncertain and assesses for?
prediction errors
Emotion Circuit - medial PFC, hippocampus to?
amygdala
to Nucleus accumbens and globus pallidus
to Nucleus of the thalamus
Social behavior circuit - Recognition of?
Social context and disapproval
- Self-regulation
- Judgement
Social behavior circuit - Ventral PFC to
Head of caudate and substantia nigra pars reticularis to Nucleus of the thalamus
Social behavior circuit - disruption can lead to?
Negative social behaviors
- Easily frustrated
- Impulsiveness
- Incontinence
Goal-directed behavior circuit - manages?
Goal-directed behavior
- learning
- Planning
- Maintaining attention and concentration
- Short-term memory
- Modifies behavior when reward is present
Goal-directed behavior circuit - DLPFC then?
head of caudate nucleus and globus pallidus to
nucleus of the thalamus
Oculomotor circuit manages?
Eye movement
Spatial attention
-Determines when fast eye movements are needed to direct attention
Oculomotor circuit - cortical motor eye fields to?
Body of caudate nucleus and SNr to
nucleus of the thalamus
Oculomotor circuit - disruption leads to?
may impair saccadic eye movements
