Afternoon session: His behavior was okay today- he missed 6 of the tests in sample-test trials (but see below). He started biting the ruler/cue at the end of the first two sample trials, so I had to push him away from it. On test 5 of sample-test trials, I think I accidentally rewarded him when he was not supposed to get a reward. He got 1/6 in post test trials. But, the last few were not triggered properly when he left the box. I just stopped recording and did not record the last sleep session. Today's session was kind of messed up for a few reasons. Yesterday, I fed him 6 pellets again. Today, the other LED and cap broke, so I am using a different LED taped in place on a different cap. 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 7. EEG seems good today. Cells on 2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, and 16 1, 14, & 15, may have cells.
