The reason why radioactive 2-DG is useful for revealing the level of activity of neurons in different parts of the brain is that 2-DG

-is absorbed by neurons in relation to their level of activity -is metabolized by neurons in relation to their level of activity

In electrooculagraphy, how many electrodes are typically used to monitor the movements of one eye?

4

Which contrast X-ray technique is designed to locate vascular abnormalities in the brains of human patients?

Cerebral angiography

Which of the following is a record of a person's heart beat?

ECG and EKG

Which method provides structural and functional information about the living human brain on the same image?

Functional MRI

Which of the following technique measures changes in magnetic fields on the surface of the brain

MEG

Which of the following procedures is not an adaptation of X-ray photography?

MRI

Which of the following provides the most detailed three-dimensional view of the structure of the living human brain?

MRI

Which of the following is a method used by cognitive neuroscientists to turn off part of the brain while the effects on cognition and behavior are assessed?

TMS

The level of 130/70 mmHg is

a healthy human blood pressure

Electrooculography is

a method of estimating eye movement

Penile erection is

a plethysmographic response.

A patient is sometimes injected with radioactive 2-deoxyglucose before

a positron emmission tomography

Which of the following biopsychologists would be most likely to study cortical ERPs in human volunteers?

a psychphysiologist

The main difference between an average evoked potential (AEP) and a "raw" evoked potential is that

a raw evoked potential is often unobservable amidst the random noise of the ongoing EEG signal

If you were startled by a loud noise, there would be an increase in your skin's conductance of electricity. This response is called

a skin conductance response

An electroencephalograph is

an EEG machine

Which of the following is a contrast X-ray techniques?

angiography

The signals in the first few milliseconds of the average auditory evoked potential

are far-field potentials and originate in the sensory nuclei of the brain stem

Unlike brain-imaging techniques, TMS permits the study of __________ between human cortical activity and cognition.

causal relations

MEG records

changes in magnetic fields on the surface of the scalp

Hypertension is

chronic high blood pressure

Vestibular function can be assessed by assessing a patient's reaction to

cold water flushed in the ear

Which technique is illustrated here?

computed tomography

Muscle tension is monitored by

electromyography

Illustrated here is

electrooculography

Electrooculography is a technique for monitoring

eye movement

Which technique records the BOLD signal?

fMRI

The short-latency low-amplitude signals (indicated by the arrow) in this average auditory evoked potential are termed

far-field potentials

A computed tomography (CT) scan of the human brain is usually presented as a series of eight or nine

horizontal sections

The P300

is an EEG wave that often occurs after the presentation of a momentary stimulus meaningful to the volunteer

The ironic case of Professor P. makes the point that

many research methods of biopsychology are used in clinical settings.

Components of AEPs recorded in the first few milliseconds after a stimulus are

not usually influenced by the meaning of the stimulus

Functional MRI requires the injection of radioactive

nothing

Functional MRI generates images of increases to areas of the brain of

oxygenated blood flow

Positron emmissions tomography is a valuable research tool because it

provides an image of brain function

Signal averaging is commonly used in the recording of ERPs because it reduces the magnitude of

random signals

Alpha wave EEG activity is associated with

relaxed wakefulness

Which of the following have traditionally been used by physicians to measure blood pressure?

sphygmomanometers

Which gland or glands directly influence the SCL and the SCR?

sweat glands

In human patients, EEG activity is commonly recorded directly from

the scalp
