Effects of adult and neonatal 6-OHDA treatment on apomorphine-induced activity. Rats were allowed 1 hr habituation to the activity cages before receiving 1 mg/kg of apomorphine HCl s.c. Panel A shows consecutive 10-min period activity scores through 120 min. Panel B refers to the total activity counts collected for the 120 min session. Activity counts per 120 min for groups given only saline were as follows: control, 646 ± 70; adult 6-OHDA, 664 ± 170; neonatal 6-OHDA, 560 ± 165. Treatments are those described under “Methods.” H, counts accumulated during the last 10 min of habituation. S refers to saline controls that received apomorphine. 6-OH N(+) refers to neonatal 6-OHDA-treated rats positive for SMB and 6-OH adult refers to adult 6-OHDA-treated rats that received apomorphine. *p < .001 when compared to saline or to neonatal 6-OHDA-treated rats.
