Table 1.

(A) Levels of dopamine, noradrenalin and serotonin (pmoles per µg of protein content) of sham-, core- and shell-lesioned animals in core, shell, caudate putamen (CPu), prelimbic (PL) and infralimbic cortices (IL). (B) Percentage difference in dopamine, noradrenalin and serotonin levels of core- and shell-lesioned animals compared with vehicle-infused sham animals in the five brain regions assayed. *p < 0.05, t-test
