Exam 5: Methods and Strategies of Research

________ is (are) a common landmark or reference point used for stereotaxic surgery.

________ refers to a histological procedure in which blood is drained and replaced by another fluid, such as a salt solution.

To record the neural activity of a brain region, researchers would use

Researchers use electric current to destroy Brain Area A and conclude that the absence of a certain behavior is due to Brain Area A. However, Brain Area A is not actually involved; instead, a brain area that was passed through was involved in the circuit of interest. How could the researchers control for this erroneous finding?

The Doogie mouse was genetically engineered to have NMDA receptors that become more efficient with age. This animal would be considered an example of a

Microdialysis is not done in humans for research purposes owing to

The most common fixative of nerve tissue is

Produced by some white blood cells, ________ are used by neuroscientists to bind specific proteins in the nervous system.

A lesion technique that is selective for cell bodies involves

Researchers want to find out which brain region comes after brain region C. To discover this, researchers can trace ________ axons using ________ labeling.

In _________________, a coil of wires is used to noninvasively stimulate neurons in the cerebral cortex.

In the ________ technique, a modified strand of RNA or DNA binds with specific molecules of mRNA, thereby preventing the protein encoded by the mRNA from being produced.

Which of the following is true of stereotaxic surgery?

_____________ are used in single-cell recording because they can record the electrical activity of individual neurons.

In _________________, neuromagnetometers are used to find the source of a seizure so it can be surgically removed.

If a child has a characteristic that is largely determined by genetics, he/she would be most similar to

Imagine that feeding behavior was eliminated when a radio-frequency lesion was used to damage the lateral hypothalamus of a rat, which suggested that cells within this region initiate feeding. If a subsequent study failed to observe a change in feeding after injection of kainic acid into the lateral hypothalamus, what conclusion would be appropriate?

Which of the following is strong evidence for an environmental contribution to a behavior?

The experimenter injects 2-DG into an animal and then exposes it to a new food. After the animal has been sacrificed, the brain is sliced and prepared for ____________ to determine what areas of the brain were activated.

A ________ is a thin slice of brain used in histology.
