Table 4. Properties of IPSPs Elicited by Single Presynaptic Action Potentials in Bistratified Cell-Pyramid Connections in the CA1 and CA2 Regions and in SP–SR Interneurone-Pyramid Connections
Postsynaptic MP (mV)
IPSP mean amplitude (mV)
IPSP half width (ms)
IPSP 10–90% rise time (ms)
The asterisks stand for values that are statistically significant. Data are represented as mean ± standard deviation (SD). MP, membrane potential. IPSPs elicited in CA2 SP–SR interneurones were similar in amplitude to those elicited in CA1 and CA2 bistratified cells (MW U, P > 0.05). The widths at half amplitude and the 10–90% rise times of the IPSPs elicited in SP–SR interneurones were similar to those of CA2 bistratified cells (MW U, P > 0.05) but briefer than those elicited in CA1 bistratified cells (MW U, P < 0.05, U = 0).
