Today is the 5th day of the full task: starts from home port, 3 rewards, sucrose instead of water, and platform rotated between trials. In addition: today I will do an extinction trial first i.e. I will allow the subject on the platform, but not place rewards. I'm interested in seeing whether the animal persists at the previously learned reward locations. In post-sleep I will do a probe trial NEW CALIBRATION Data1: extinction (this will be interesting because the last time he did the task was 6 days ago) Data2-35: trials Data36: post-sleep probe to check memory NOTES: -Data18: animal reversed route from counter clockwise to clockwise -Data19: reverted to original route. -The platform was wiped down after trial 20. A little break also. -catch trial on trial 21
