Data are expressed as mean ± SEM. Numbers in parentheses indicate the number of neurons. NS1, the distribution of the values obtained from whole DiI(+) neurons was not significantly (p > 0.05) different from that from whole DMX neurons that were recorded without preceding retrograde labeling (Kolmogrov-Smirnov test). *, significantly different from the distribution of the values from whole DMX neurons. NS2, not significantly different between type I DMX and type II DMX neurons (p > 0.05).
