Firing Pattern Parameters for a Standard Session and a Succeeding Card-together Session
| Standard | Together | Difference | Paired t | P | |
|---|---|---|---|---|---|
| Grand rate | 0.747 ± 0.792 | 0.61 ± 0.63 | −0.136 ± 0.673 | 1.55 | 0.13 |
| Field rate | 4.03 ± 2.420 | 3.45 ± 2.06 | −0.577 ± 1.502 | 2.95 | 0.005 |
| Centroid rate | 12.09 ± 11.51 | 7.46 ± 7.65 | −4.635 ± 10.62 | 3.35 | 0.001 |
| Size | 593.7 ± 361.1 | 576.3 ± 52.2 | −17.4 ± 398.7 | 0.34 | 0.74 |
| Coherence | 1.046 ± 0.285 | 0.979 ± 0.225 | −0.067 ± 1.056 | 1.95 | 0.06 |
| Information | 3.55 ± 1.18 | 3.49 ± 1.16 | −0.059 ± 1.056 | 0.43 | 0.67 |
The probabilities for the t values indicate decreases in three different measures of firing rate, although the decrease in grand rate is only a trend. The decrease in coherence was also only a trend, suggesting that the field was noisier. There was no change in field size nor information per spike.
