↵Data are the number of action potentials elicited in response to a 300 pA current injection for 1 s. The ratio of cells changed refers to the number of individual neurons (relative to the total number of neurons recorded) whose action potential output at 300 pA was more than 2 SDs beyond the mean of neurons from NAIVE rats. Data from the TRACE group are significantly different from the NAIVE, PSEUDO, TRACE-RET (*p < 0.01), and EXT (**p < 0.05) groups.
