dorsolateral frontal lobe

A

executive function

24
Q

accumbens

25
Q

left inferior frontal

26
Q

Ventral tegmental area

A

rewarding and aversive qualities of sensations

Neurons rich in dopamine project from this area to the nigrostriatal pathway.

27
Q

Anterior cingulate

A

activated in tasks involving emotion, cognitive and motor tasks

28
Q

hippocampus

A

Damage to this area bilaterally leads to an amnestic syndrome

29
Q

Nucleus basalis

A

Major cholinergic site involved in pathogenesis of Alzheimer’s dementia.

30
Q

Locus Coeruleus

A

Noradrenergic neurones

31
Q

orbitofrontal cortex

A

change in personality with childlike behaviour and disinhibition.

32
Q

thalamus

A
  1. translator of prethalamic inputs into readable form. 2. process and relay of sensory information selectively to the cerebral cortex. 3. regulation of sleep and wakefulness. 4. consciousness arousal, the level of awareness, and activity.
33
Q

Thalamic syndrome:

A

contralateral hemianaesthesia, often accompanied by mood swings

34
Q

olivary nucleus- inferior

A

finger-nose

35
Q

Wernickes

A

Mamillary bodies

36
Q
