Physio Ch. 5

Research Methods and Biopsychology

Produces 3-D and 2-D images Produced by waves from hydrogen atoms Magnetic Resonance Imaging (MRI)
Uses X-Rays Computed Temography (CT or CAT scan)
Inject radioactive 2-DG Position Emission Tomography (PET)
Visualizing blood flow/oxygen use in the brain Functional MRI (fMRI)
recording physiological activity from the body surface EX: blood pressure, skin conduction response (measuring sympathetic nervous system) Recording Psychophysiological Activity
Measuring brain activity Electroencephalogram (EEG)
Animal Research: -Lesioning -electrical stimulation -manipulating or measuring within the brain Invasive Research Method
Remove, damage, or destroy a part of the brain lesion methods
-electrical stimulation may be used to "activate" a structure Electrical stimulation
-Fed to the subject -Injected-described by injection sight: stomach (intragastric), perioneal cavity (intraperitoneal), large muscle (intramuscular), tissue under the skin -Cannula-directly to the brain Routes to drug administration
based on the binding of labeled protein- specific anitbodies immunocytochemistry
-knockout mice -subjects missing a given gene can provide insight into what the gene controls -taking away a gene gene knockout techniques
-transgenic mice -transfering a gene into a mouse gene replacement techniques
mimic situation that an animal might encounter in its natural environment seminatural learning paradigms
animals appear prepared to associate tastes and illness conditioned tast aversion
test spatial abilities and memory radial arm maze/morris water maze
did he like that drug? positive association conditioned place preference
Open Field Test-general activity, fear Grooming after eating Colony intruder paradigm- aggression and defensive behavior assessment of species common behavior
Classical Conditioning- Pavlov's Dogs, food aversion Operant Conditioning- self stimulation- animal works for electrical stimulation or food Traditional Conditioning Paradigm
