BNS- Research methods
The open- field test is usually conducted in
A large empty chamber
Stereotactic surgery in human patients typically requires
A stereotraxic atlas A steeotaxic instrument A head holder An electrode holder
In immunocytochemestry, the labeled ligand is
An antibody
The self stimulation paradigm is
An operant conditioning paradigm
The reference point for many stereotaxic atlases of the art brain is
Bergma
If a rat receives a single painful stimulus from a small object in a test box containing commercial bedding materia;. The rat will Isaí;;y investigate the object and then
Bury it
MEG records
Changes in magnetic fields on the surface of the scalp
A temporary or reversible lesión can be produced by
Cooling the target brain structure or injecting an anasthetic into it
In the typical radial arm maze, rats tend o orient themselves on the basis of
External room cues
Intercellular unit recording is particularly difficult in
Freely moving animals
A computed tomography (CT) scan of the human brain is usually presented as a series of eight or nine
Horizontal sections
Which of the following procedures employed labeled antibodies
Immunocytochemistry
The typical Morris water maze
Is circular
Reversible lesions can be produced by micro injection directly into the target brain structure of a
Local anesthetic such as lidocaine
Which of the following is a weakness of the gene knockout technique as a method of biopsychological research
Most behavioral traits are influenced by the many interacting genes Elimination of one gene often influences the expression of other genes The effects of some gene knockouts are likely to depend on experience
The neurotoxin, 6-hydroxydopamine ( 6-OHDA) selectively destroys
Neurons that release dopamine or norepinephrine
Functional MRI generates images of increases to areas of the brain of
Oxygenated blood flow
A patient is sometimes infected with radioactive with 2-deoxyglucose before
Positron emission tomography
In most self-stimulation paradigms, laboratory animals
Press levers or perform other operant responses to obtain reinforcement Receive electrical stimulation through implanted electrodes
Reversible brain lesions, if properly done,
Produce no permanent neural damage
The digit span test is a common test of
Short term memory
The Morris water maze is commonly used to study
Spatial ability in rats
In a laboratory animals, cortical EEG signals are commonly recorded through
Stainless steel skull screws
If a PET image is recorded while a patient is reading, many areas of activity on the PET he will have nothing to do with the cognitive activity of reading per se. THat is why cognitive neuroscientists often use
THe paired-image subtraction technique
Unlike other electro physical methods of recording neural activity, intracellular unit recording provides measurements of
The membrane potential.
In human patients , EEG activity is commonly recorded directly from
The scalp
Drugs that do not penetrate the blood brain barrier can be ministered to particular neural structures
Through a stereo taxi ally positioned cerebral cannula
Anti anxiety (anxiolytics) drugs tend to reduce the amount of
Time spent in the closed arms of the elevated plus maze Conditional defensive burying
During conventional Pavlovian conditioning, the conditional stimulus is repeatedly presented just before the
Unconditional stimulus
A common neuropsychological test of frontal-lobe damage is the
Wisconsin card sorting test
Knockout mice are mice that
dont have a concussion Are not succeptible to concussion Dont have amnesia
Which technique records the bold signal?
fMRI
Which method provides structural and functional information about the living human brain on the same image?
functional MRI
Transgenic mice always possess
genes of another species
