Q

what are photocells used for in conditioned place preference test

A

they allow for automatation (they are in both chambers so maybe help with some consistency idk)

Q

how can you compare the abuse potential of 2 drugs using conditioned place preference test

A

train rat with 1 drug, then substitute with another drug and see if it can substitute it well for the animal

Q

what are rats trained to do in drug discrimination (and in response to wait)

trained to press a lever in response to light (example, press right lever with green light)

Q

what do you do in the drug discrimination test after you established that light=lever=reward

A

inject with vehicle or drug before placing it in the chamber

18
Q

in the drug discrimination tests, what are you pairing an event with (2 things, what first then after)

A

a reward, then drug or saline

19
Q

what happens once the animal knows to press the right or left lever when given either drug or saline? (Whats the next step)

A

remove the light to see if the animal will press the lever with just drug input

20
Q

how will you know if an animal thinks 2 drugs are the same in a drug discrimination trial

A

a drug that the rat perceives to be the same will result in right lever presses

21
Q

does the drug have to be addictive to work in drug discrimination tests

22
Q

what is required for a drug to pass as being similar in a drug discrimination test (even if its not addictive)

A

it has to generate a response that is different from your regular state

23
Q

what is a drug detection procedure

A

the process of drug discrimination trail test thing

24
Q

what is the elevated plus-maze / y-maze based on

A

the fact that rodents would rather be in the enclosed arms than in the open arms

25
what do they score/measure in the elevated-plus maze
the entries and time spent in the open arms vs closed arms
26
which arms in the elevated-plus maze gives more anxiety to rats
when they are in the open arms
27
what does anti anxiety drugs in the elevated-plus maze do to rat
increases the time in the open arms
28
do benzodiazepines work in the elevated-plus maze paradigm
yes
29
does buspirone work in the elevated-plus maze paradigm
no
30
which drug is expected to work in the elevated-plus maze but doesnt work
buspirone
31
what is mechanism of action of the buspiron
5HT1A antagonist
32
what is the vogel test (what happens in the procedure)
you punish drinking water with mild electrical shocks, then see how drugs can change their behaviour
33
what is the reason for performing the vogel test
fast screening of the potential anxiolytic properties of drugs
34
what reestablishes drinking responses in the vogel test
drugs with anxiolytic properties
35
does buspirone work in the vogel shock test
no
36
what does the water maze test for
learning and cognition
37
how is the water maze set up
large circular pool of water with a hidden platform, visual cues help them find it again
38
how many trials in the water maze is usually required to get to the platform quiz
2-3
39
how can we use the morris water maze to test for drugs and disease
see what can affect memory and learning, like benzos or cognitive enhancers
40
can brain damage inhibit the water maze results (and where is the damage important)
yes, mostly in the hippocampus
41
what are 2 treamtments for alzheimers
cholinesterase inhibitors and memantine
42
why is cholinesterase inhibitors used for alzheimers
they are designed to prevent the breakdown of ACh which is important for memory and thinking skills
43
why is memantine used for alzheimers
it regulates glutamate which serves to process, store and retrieve info
44
what was the point of using the radial arm mase
measure spatial memory
