Effects of the reversible spinalization on different characteristics of neuronal discharges. A, B, Effect on the mean frequency of activated (A) and inactivated (B) F-neurons, E-neurons, and NM-neurons. C–F, Effect on the mean burst and interburst frequencies of F-neurons (C,D) and E-neurons (E,F) activated (C,E) and inactivated (D,F) by the cold block. *p < 0.05; **p < 0.01; ***p < 0.001.
