BDNF injection into the shell of the NAc does not alter ethanol self-administration. Rats were microinjected with PBS or BDNF (0.25 μg/μl/side and 0.75 μg/μl/side) into the shell of the NAc 3 h before the beginning of the operant ethanol self-administration session. Number of lever presses (a) and ethanol consumption (b) were similar between the two groups. n = 5.
