Values are means ± SD.

^*Significantly different from primary pyramidal cells, Student’s t-test, P < 0.0167. There was a significant effect of cell type on all three parameters [1-way ANOVA, LatMn:F(5.81)=4.002. P < 0.01: AEPSP:F(5.81)=6.748. P < 10^-4: t_{HW EPSP}:F(5.81)=3.556. P <0.01]. Other symbols indicate statistically significant differences between groups as assayed by Bonferoni’s or Dunnett’s T-3 post-hoc tests (P < 0.05):

^†different from primary LIII-V interneurons;

^‡different from shell pyramidal cells;

^§different from primary and shell pyramidal cells.
