Abstract

ln the present study the effect ofrepeated intracerebroventricular (ICV) of anti-conjugated dopamine antibodies (Acm anti-DAc) was investigated on behavioural supersensitivity and eating behavior. Mice were injected in ICV (with an ICV cannula) with either Acm anti-DAc or no immuns immunoglobulins (IgNI) twice a week for 5 weeks, their behavioural supersensitivity to apomorphine (0.05 mglkg) were measured. The results showed that Repeated intracerebroventricular injections of anti conjugated dopamine antibodies produced a behavioural supersensitivity to apomorphine. Immunohistochemical analysis showed that the behavioural supersensitivity is not due to DA celllosses in the substantia nigra or the ventral tegmentum area.
