Experimental Flashcards
quantitative; cause and effects; treatments are ind and effects are dependent (34 cards)
experimental research
quantitative; cause and effects; treatments are ind and effects are dependent
non-experimental
surveys
correlational studies`
non-experimental; looking at how two variables are related
qualitative studies
applied research
fix every day problems
basic research
understand processes
neuroethology
studying neural basis of an animals natural behaviors
drug addiction
self-adminstering button technique(press to send yourself drugs)
time in drug chamber (go to room for drugs)
cognition
morris water maze
fear
fear conditioning beeping=shock
anxiety
light dark box; bigger light area and more smaller darker area, measure how long they spend in one
elevated bridge maze: spend more time in closed secure or no railing edges
open field: how much will they go and explore new areas
reward
intracranial stimulation: shock the brain–>feels good
ways to structurally see the brain
mri, CT, xray, dti
ways to see brain functionally
fmri,PET, spect, asl
xray
looking at more density = less beams go through= lighter picture
cat/ct scan
processed xrays to create a single image
mri
shaking hydrogen atoms to determine if they move a lot or not
fmri
blood oxygen levels due to amount of activity in the brain is stimulated
PET
tracer into blood to bind to brain
DTI
looking at formation of water molecules on axons
cytoarcitecture
how the cells are arranged in the nerous system
histology
study of microscopic structures
perfusion
draining blood and filling with fluids to remove brain
fixation
chemical used to maintain brain tissue after removal (FORMALDEHYDE)
