The effects of unilateral 6-hydroxydopamine lesions in the substantia nigra on hippocampal noradrenaline-induced feeding and other behaviour in the rat.
The latency, duration of feeding and number of feeding periods recorded from rats after noradrenaline injection to the hippocampus show little change after unilateral 6-hydroxydopamine injections to the substantia nigra. It is suggested that 6-hydroxydopamine-induced weight losses result from non-specific effects of injection because increased durations for grooming, decreased latencies for resting and short periods of feeding follow injection.
