Q

Where is the limbic system located?

A

Cerebrum

17
Q

Which area is the main source of sensory input (besides olfaction) to the cerebral cortex?

A

Thalamus

18
Q

What is the role of the hypothalamus?

A

To convey messages to the pituitary gland, altering its release of hormones

19
Q

Damage to the _ impairs movement & may cause Parkinson’s & Huntington’s disease

A

Basil ganglia

20
Q

What is the function of the dorsal roots of the spinal cord?

A

They receive sensory input

21
Q

What does the parasympathetic nervous system do?

A

Controls vegetative activities, increase digestion, & decreases heart rate

22
Q

What do the ventricles contain?

A

Cerebrospinal fluid

23
Q

The cells on the outside of the cerebral cortex are _ matter & their axons extending inward are _ matter

A

Gray, White

24
Q

What controls movements of the contralateral side of the body?

A

Primary Motor Cortex

25
Q

Which lobe includes the primary motor cortex?

A

Frontal lobe

26
Q

When does binding occur in the brain?

A

When you perceive two sensations happening at the same time & in approx. the same place

27
Q

What is the binding problem?

A

The question of how we perceive diff sensations as part of a single object

28
Q

What part of the cortex is important for working memory & decision making?

A

Prefrontal cortex

29
Q

Damage by means of a stereotaxic instrument for precise electrode placement in the brain is known as

A

A lesion

30
Q

What is the difference between an MEG & an EEG?

A

An EEG records electrical activity of the brain, an MEG measures the magnetic field

31
Q

If you were trying to detect a brain tumor, what would you do?

A

CT/Cat Scan

32
Q

What is the difference between an ablation & a lesion?

A

Ablation is the removal of a brain area with a surgical knife, a lesion is controlled damage in laboratory animals

33
Q

What is a method to inactivate a brain area temporarily?

A

Transcranial magnetic stimulation (TMS)

34
Q

Q: What does the optogenetic technique enable researchers to test?

A

The functions of a neuron

35
Q

What are EEG’s & MEG’s both good for measuring?

A

Changes in brain activity over a short period of time
