Brain & Behavior, Chapter 8

Which basal ganglia structure(s) is(are) important for receiving input from sensory areas of the thalamus and the cerebral cortex?

Caudate nucleus and putamen

Most of the axons of the dorsolateral tract go to which side of the body?

Contralateral

Parkinson's disease is caused by degeneration of a pathway of neurons that releases which neurotransmitter?

Dopamine

Which of the following would most likely happen with damage to the prefrontal cortex?

Poorly planned movements.

From where do most of the axons in the dorsolateral tract originate?

Primary motor cortex and red nucleus

The psychological disorders that accompany Huntington's disease could be mistaken for which of the following?

Schizophrenia

In Parkinson's disease, which pathway in the brain degenerates?

Substantia nigra to the basal ganglia

Dorsolateral tract axons are responsible for movements in the:

arms, hands, and toes

Cigarette smoking and coffee drinking ________ the risk of Parkinson's disease, and marijuana ________ the risk.

decrease; increase

The reason why a dopamine pill is ineffective for treating Parkinson's disease is that:

dopamine does not cross the blood-brain barrier

The part of the cortex which is most active during preparations for a movement and less active during the movement itself is the:

premotor cortex

A quick typist would rely heavily on the _______ cortex to organize smooth sequences of finger movements.

supplementary

Which parts of the brain deteriorates most strongly in Huntington's disease?

the caudate nucleus, putamen, and globus pallidus

The tract that includes many axons from the primary motor cortex, the reticular formation, and the vestibular nucleus is the:

ventromedial tract

People with posterior parietal damage:

will not step over an obstacle, although they can accurately describe it.
