The data were fitted by a sum of 1st and 2nd θ harmonics with equation y = [A0 + A1 sin (π* (x + A2)/180) + B1 sin (π* (x + B2)/90)], where A0 = phase-independent constant, A1 = 1st harmonic modulation, A2 = 1st harmonic phase shift, B1 = 2nd harmonic modulation, and B2 = 2nd harmonic phase shift. R 2 describes the goodness of the fit with degrees of freedom (df). LTP was averaged for different periods after bursting: LTP1 (0–30 min), LTP2 (30–60 min), LTP3 (60–90 min), and LTP4 (90–120 min). B1/A1 ratio increased with time;
↵** p < 0.005, *p < 0.05, R 2 significantly different from random pairing of x and y values.
