CBN Final Exam Questions And Accurate Answers
Primary motor cortex
Plan, initiate, and direction of voluntary movement
Hippocampus - CA3
Learning and memory; spatial learning
Substantia Nigra
Part of Basal Ganglia; suppress unwanted movement and prepare motor cortex for
initiation of movement
Periaquecductal Gray (PAG)
Pain suppression
Dorsal Raphe Nucleus
Source of serotonin; contain opioid neurons
Cerebellum
Smooth coordinated movement; coordinated control; motor learning
Micro punch
Slicing a section out of a brain, staining it to identify RNA or proteins that signal levels of
expression
Immunostaining
Take a section of brain and mount it onto a slide. Process it and stain so RNA and
proteins stand out
, RT-PCR
A methodology in which RNA is first transformed into cDNA using the enzyme reverse
transcriptase, then those resultant cDNA are amplified by the polymerase chain
reaction.
Western blot
Immunoblotting technique that, through the use of electrophoresis, separates the
proteins in a sample by size. Proteins are stained down a gel blot.
RNA Sequencing
Fragmenting RNA and making cDNA with reverse transcriptase. cDNA fragments are
sequenced with computing technologies and analyzed to understand transcriptome of
specific regions of the brain and provide insight into gene expression patterns and
mechanisms for normal/diseased brain function
Electrophysiology
data collection method that measures electrical activity in the brain. This can be done
by using skull land marks, and killing the cells involved in certain areas of the brain to
"inactivate them". This is done for testing how different drugs affect areas of the brain
