Effects of prenatal cocaine treatment on the postnatal expression of homer 1.

Mean density values (mean±SEM) measured in different striatal regions on rostral, middle and caudal levels are given for mice that were prenatally exposed to saline (PSAL) or cocaine (PCOC) and tested at postnatal days (P) 15, P36 or P60 after an injection of saline (sal) or 15 mg/kg cocaine (coc). Responses to the cocaine challenge are also shown in percentage of values in respective saline controls (%). Striatum (S): m, medial; dl, dorsolateral; c, central; l, lateral; v, ventral; tot, total. Nucleus accumbens (NA): C, core; Sm, medial shell; Sl, lateral shell.
