Figure 4

Dose effect of nicotine on locomotor activity across the 10-day repeated treatment phase (n=16 rats per dose). Rats were given one habituation day (designated as `H') prior to the 10 treatment days. Data are expressed as the mean (±SEM) total distance traveled (cm) per day. Asterisks indicate a significant difference from the saline control value on the corresponding treatment day (*p<.01). The hache symbol above the line in the upper portion of the figure designates a significant difference from saline for each nicotine dose across Days 5-10 (#p<.01).
