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
