Question 5

It is likely that genetics explain some of the attention deficits of ADHD, because

2. unaffected siblings perform as poorly as ADHD siblings.
3. only dizygotic siblings are affected.
4. none of the above.

Answer 5

1. unaffected siblings perform better than ADHD siblings but worse than controls.

Question 6

The directional coding of populations of neurones in the primary motor cortex means that

1. one group of neurones will activate maximally to the forthcoming required direction of limb movement to the target.
2. many groups of neurones will respond, and the average of their activations will code the actual direction of the movement.
3. only one group of neurones activates to the forthcoming required direction of limb movement to the target, and all other activations are inhibited.
4. none of the above.

Answer 6

1. one group of neurones will activate maximally to the forthcoming required direction of limb movement to the target.

Answer 10

neurones generated early form the bottom layers of the cortex (L5-6) while later-generated neurones form the top layers (L1-4).
