1 Differential effect of haloperidol on release of neurotensin in extrapyramidal and limbic systems. Haloperidol neurotensin Homo sapiens
2 The effect of the antipsychotic drug haloperidol on extracellular neurotensin-like immunoreactivity was investigated by microdialysis and compared with the time-dependent response of tissue neurotensin-like immunoreactivity content in brain structures containing dopamine nerve cell bodies and terminals. Haloperidol neurotensin Homo sapiens
3 A single administration of haloperidol (1 mg/kg) increased the extracellular neurotensin-like immunoreactivity levels in nucleus accumbens as measured by microdialysis, but decreased its extracellular concentration in the caudate regions surrounding the probe. Haloperidol neurotensin Homo sapiens
4 These findings suggest that varied neurotensin systems are associated with nigrostriatal and mesolimbic dopamine pathways and these systems have different responses to haloperidol. Haloperidol neurotensin Homo sapiens
5 The changes in the release of neurotensin may contribute to altered caudate and accumbens neurotensin-like immunoreactivity tissue content induced by haloperidol treatment, but other factors, such as variation in synthesis also likely influence these effects. Haloperidol neurotensin Homo sapiens
6 The changes in the release of neurotensin may contribute to altered caudate and accumbens neurotensin-like immunoreactivity tissue content induced by haloperidol treatment, but other factors, such as variation in synthesis also likely influence these effects. Haloperidol neurotensin Homo sapiens
7 Differential actions of haloperidol on neurotensin release might be due to regional differences in dopamine or sigma receptor subtypes associated with the neurotensin-containing neurons. Haloperidol neurotensin Homo sapiens
8 Differential actions of haloperidol on neurotensin release might be due to regional differences in dopamine or sigma receptor subtypes associated with the neurotensin-containing neurons. Haloperidol neurotensin Homo sapiens
