  • Numbers indicate average cross-correlation coefficients ± SEM within or between the respective groups of neurons. A refers to the coefficients during spontaneous activity, whereas B refers to the coefficients after systemic administration of picrotoxin. All corresponding values between A and B are significantly different (allp values <0.01).
