Final Test

Question 1

Golgi Stain

Answer 1

A histological stain that fills a small proportion of neurons with a dark, silver-based precipitate

Question 2

Nissl stain

Answer 2

A histological stain that outlines all cell bodies because the dyes are attracted to RNA, which encircles the nucleus

Question 3

Autoradiography

Answer 3

A histological technique that shows the distribution of radioactive chemicals in tissues

Question 4

Immunocytochemistry (ICC)

Answer 4

A method for detecting a particular protein in tissues in which (1) an antibody recognizes and binds to the protein and (2) chemical methods are then used to leave a visible reaction product around each antibody

Question 5

In situ hybridization

Answer 5

A method for detecting particular RNA transcripts in tissue sections by providing a nucleotide probe that is complementary to, and will therefore hybridize with, the transcript of interest

Question 6

immediate early genes (IEGs)

Answer 6

A class of genes that show rapid but transient increases in expression in cells that have become activated

Question 7

c-fos

Answer 7

An immediate early gene commonly used to identify activated neurons

Question 8

horseradish peroxidase (HRP)

Answer 8

An enzyme found in horseradish and other plants that is used to determine the cells of origin in a particular set of axons
