Species comparison of AP and eIPSP frequencies.

Two sample Student’s t-test (t, p) comparing various parameters in mice (n = 3), guinea pigs (n = 3) and rats (n = 3). CA3 AP frequency: mean firing rate; CA3 eIPSP frequency: mean frequency of eIPSP occurence. cross-corr AP count: % of mean AP count in the considered bin (onset Ex, peak Ex, max Ib, recovery: cf Methods and Fig. 3). cross-corr time: time of occurence of the considered bin (onset Ex, peak Ex, max Ib, recovery: cf Methods and Fig. 3). onset Ex: excitation onset bin. peak Ex: excitation peak bin. max Ib: maximal inhibition bin. recovery: recovery bin. Note that besides the time of occurence of the excitation peak in mice compared to guinea pigs, none of the tested values were significantly different between species.
