Table 2. summarizes the DR neuronal activity of all animals.
Table 2 summarizes the acute and chronic effect of MPD injection on DR neuronal activity from all experimental groups (0.6, 2.5, and 10.0 mg/kg MPD).
indicates a significant (p < 0.05) increase in activity following MPD treatment,
indicates a significant (p < 0.05) decrease in neuronal activity following treatment, and
indicates no change. Acute summarizes the acute effect of MPD; Baseline compares neuronal activity following rechallenge MPD exposure to the initial effect of MPD at ED1.
