highly significantP < 10 –43
Subsequent memory effects in selective neurons Due to the preceding screening procedure, we found highly significant fractions of neurons responding selectively to one or more items in all recorded brain regions (all P < 10 –43 , binomial test, one-sided with n = total number of neurons per region, k = number of responsive neurons per region, P = 0.001, corresponding to the alpha level of our response criterion, refer to “item responses”, Fig. 2 , Fig.
