Summary of the data set on which this report is based
| Group | N | Stimulated sites | Area (mm2) | EPSCs | IPSCs |
|---|---|---|---|---|---|
| P20 to P22 | 7 | 921.3 ± 168.0 | 1.41 ± 0.28 | 185.4 ± 40.6 | 136.7 ± 6.7 |
| P30 to P35 | 9 | 1,030.2 ± 155.3 | 1.78 ± 0.19 | 363.7 ± 69.6 | 338.0 ± 68.3 |
| P36 to P40 | 19 | 1,133.3 ± 115.4 | 1.81 ± 0.29 | 278.4 ± 45.8 | 213.0 ± 29.7 |
| Mature | 29 | 920.3 ± 137.9 | 1.47 ± 0.24 | 113.2 ± 14.1 | 76.8 ± 12.5 |
| Total | 64 | 1,001 ± 49.1 | 1.61 ± 0.12 | 235.2 ± 42.5 | 191.1 ± 29.3 |
The average number of locations stimulated, and the average area encompassing those sites, were similar for all ages, but the numbers of sites that when stimulated evoked excitatory post-synaptic currents EPSCs and inhibitory post-synaptic current (IPSCs) changed significantly. All numbers are means ± standard error of the mean.
