Cog Neuro Final Flashcards

1
Q

Orbitofrontal Cortex

A

Prediction for decision making and rewards
Those with lesions become impatient for Temporal Discounting

More for taste preference
Price (like on wine) impacts perception of how it tastes and OFC tracks this
Also about socially inappropriate behavior

Q

Anterior Cingulate Cortex

A

Conflict resolution and error detecting. Greater activity for hard or difficult (incongruent trials like in the Stroop task when its the wrong color with the word. but then activation gets less because you are anticipating the incongruency)

Responds to valence for social cognition

Involved in PAIN

Is in the medial frontal cortex

Q

Amygdala

A

Fear response and social judgement

Low road:
quick, autonomic reactions. fight or flight response. directly from thalamus

High road:
slower but more accurate. higher level judgements. from thalamus, but then to sensory cortex

Lesions create no fear response

Emotional memories are more salient
More active to fearful faces

Q

Spatial Neglect

A

UNILATERAL
Damage to one hemisphere leads to the good hemisphere “locking” and can’t see anything outside that hemisphere
Can be directed to it but can’t “see it” on own

32
Q

Subcortical Attention

A

Lateral geniculate nucleus
Superior Colliculus
Pulvinar

33
Q

Lateral geniculate nucleus

A

Where vision comes from in the thalamus
Activity increases with attention

34
Q

Superior Colliculus

A

Behind corpus callosum
Controls eye movement

35
Q

Pulvinar

A

Role in covert attention

36
Q
