Values are results of analysis of how age, sex, and concentration alter GL nerve responses in control rats. We did not assume sphericity for the repeated measure (i.e., concentration), and we present corrected P values according to the Greenhouse-Geisser procedure. For clarity, we present uncorrected df.
