Number of astrocytes | Oscillation frequency mean ± SE I pulse | Change in frequency (%) mean ± SE II pulse | Change in frequency (%) mean ± SE III pulse | |
---|---|---|---|---|
CA1 | 132 (20) | 1.55 ± 0.11 | +28.4 ± 5.6 | +44.7 ± 8.7 |
CA1 subpopulation | 57 (20) | 0.66 ± 0.02 | +46.2 ± 7.9 | +98.8 ± 13.7 |
Visual cortex | 15 (4) | 1.05 ± 0.13 | +47.4 ± 13.1 | +53 ± 7.41 |

The time interval between stimuli, unless specified, was 10 min. Values in the second and third pulse column indicate the average increase in oscillation frequency in the second and third pulse, respectively, as compared with the oscillation frequency in the first pulse. Numbers in parentheses indicate the number of experiments. ND, Not determined.
