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
