Abstract
A microdialysis probe was placed in either the shell or core compartment of the nucleus
accumbens and rats were exposed to mild footshock. Extracellular dopamine levels in
the shell of the nucleus accumbens were elevated during the 20-min collection period
immediately after discontinuing footshock. In contrast, the levels of dopamine remained
unaltered in the core of the nucleus accumbens.
