Afternoon session: He ran poorly today. He ran straight through the first 6 trials, and he got 1/8 tests of sample-test trials correct. He got 2 or 3/6 in post test trials. Yesterday, I fed him 5 pellets, but Andrew has accidentally given him free food earlier in the day. I am using an LED taped in place on a cap today. sleep 5 min pre-running: 6 laps, no reward. sleep 5 min sample-test: 8 trials sleep 5 min post-test: 6 tests sleep 5 min The circular track was rotated today, and the animal box was close to the shelf. The reward location was 14. EEG seems good today. Cells on 1, 2, 3, 4, 7, 8, 9, 10, 11, 12, 13, 15, and 16 5 and 18 may have cells.
