a) Neocortex
b) Reflex pathways
c) Hippocampus
d) Basal ganglia

Answer 17

d) Basal ganglia

Question 18

Mesolimbic and mesocortical pathways originate in Substantia Nigra.
True or False

Answer 18

False

Question 19

Medial orbitofrontal cortex shows increasing activity with increasing reward.

Answer 19

True

Question 20

Which of the following is not true of orbitofrontal cortex?

a) It is a projection zone of dopaminergic neurons
b) It is a point of multimodal convergence
c) It synthesizes dopamine
d) It represents value of reward

Answer 20

c) It synthesizes dopamine

Question 21

In reward prediction error approach, dopaminergic neurons do not burst at:

Answer 21

predicted reward

Question 22

Temporal discounting is a preference to select small but immediate reward over a larger but delayed one.
True or False

Answer 22

True

Question 23

What is a correct definition of PFC?

Answer 23

The part of frontal cortex that does not elicit movement when stimulated

Question 24

Which structure is relevant for error detection and resolution of conflicts?

Answer 24

Anterior Cingulate Cortex (ACC)

Question 25

In incentive salience approach of dopaminergic system, dopamine mediates only the liking component of reward

Answer 25

False

Question 26

Premotor Cortex (BA 6) is a part of prefrontal cortex.
True or False

Answer 26

False

The premotor cortex, also known as Brodmann area 6, is not considered to be a part of the prefrontal cortex (PFC).
The premotor cortex is located in the frontal lobes of the brain, just anterior to the primary motor cortex. It is involved in the planning and execution of movement, as well as in the control of attention and perception during movement.

Question 27

The relative size of PFC is highest in humans across all animals
True or False

Answer 27

False
Great apes such as chimpanzees and orangutans have a PFC that is larger relative to the rest of the brain than in humans.

Question 28

Which of the following is not a consequence of PFC lesions?

a) perseveration errors
b) deterioration of IQ
c) deficiency in foresight and planning
d) loss of spontaneity

Answer 28

b) deterioration of IQ

Question 29

What is a neuropsychological test for perseveration?

Answer 29

Wisconsin Card Task

Question 30

In Stroop task, people are fast at reading words, but slow at naming colours.
True or False

Answer 30

True

Question 31

Anterior cingulate cortex is a part of neocortex.
True or False

Answer 31

False

Question 32

A stimulus whose removal encourages (reinforces) certain behavior is called:

Answer 32

negative reinforcer

Question 33

Dopamine mediates only liking component of reward
True or False

Answer 33

False
Dopamin is involved in both the liking and wanting components of reward.
