Figure 2. — Capsaicin but not menthol decreases mEPSC interevent intervals in lamina X neurons. (Aa) Representative recording showing decreased interevent intervals during capsaicin application. Note that capsaicin elicited inward currents in 3 of 7 lamina X neurons. (Ab) Changes in mEPSC interevent intervals for all tested neurons; horizontal bars indicate median values. (B) Miniature EPSCs recorded in the presence of menthol (no effect) and capsaicin. Scale bars: (A, B) (1 minute, 10 pA). *P < 0.05. mEPSCs, miniature excitatory postsynaptic currents.
