Note: Means ± SEM are presented; n represents the number of neurons sampled; the number in parenthesis after the n value represents the number of experiments performed to obtain that number of cells. *P < 0.01, **P < 0.05; both significantly different with respect to the corresponding NCB value. Significance determined with 1-way ANOVA followed by Fisher's PLSD (minimal PSP data) or Student's t-test (asynchronous PSP data).
