Neonatal astrocytes exhibit two distinct electrophysiological phenotypes. a Two whole-cell voltage clamp recordings from a P1 (left) and a P3 (right) neonatal astrocyte, respectively. The cells were held at −80 mV at resting, and the 50 m voltage commands (V COM) were from −180 to +20 mV with 10 mV increments. b The variably rectifying astrocytes (VRA) show multiple rectification points in I-V plot, whereas the I-V plot in passive astrocytes (PA) was rather linear. c PAs first appeared in P2 (6.67 %) and increased to 20.83 % in P3. d The percentages of VRAs and PAs in P1-3 stratum radiatum region. e The V M values in VRAs and PAs are comparable in neonatal astrocytes, but are significantly more negative than those of astrocytes > P21. f The Rin varied markedly in VRAs and was significantly higher than PAs in both neonatal and adult animals.*: P < 0.05. N.S, P > 0.05
