Effects of nicotine on neurotensin-like immunoreactivity (NTLI) levels in ventral tegmental area-related brain regions such as the prefrontal cortex (Fig. 4A) and the nucleus accumbens [core (NAc) and shell (NAs); Fig. 4B]. Animals were given injections of nicotine (as described for Fig. 1) or saline and killed 12 and 24 h following the treatment. Results are expressed as percentages of control and represent mean values ± S.E.M. (n= 8 control and 9 drug-treated animals per group). The average control values of NTLI concentrations for prefrontal cortex, NAs, and NAc were 37 ± 6 pg/mg protein, 270 ± 21 pg/mg protein, and 408 ± 26 pg/mg protein, respectively. *P < 0.05 vs. control.
