Day 15

CTA Testing
Today, we began CTA testing with group C and group D.  Before testing them, we had to weigh all the rats.  We could run a maximum of 8 rats at a time.  We first gave each rat saccharine for one hour and then injected them with LiCl directly after.  The LiCl makes the rats feel sick which they then associate with the saccharine they just drank.  The goal is for their lick count to decrease the next day when they are given the saccharine again.  We run each rat and then clean out their cages in between.  After the rats finished with CTA testing, we reattempted microinjections for three rats.  The air bubble only moved in both tubes for one rat so we ran him alone and quit trying the reinjections for the others.  We agitated the cannulae of all other rats.
