Constant potential amperometry (CPA) was used for in vivo recording of extracellular dopamine (DA) after electrical stimulation of the medial forebrain bundle (MFB) (4 pulses, 2 mA, 20 or 100 Hz) in the striatum of the rat brain. CPA signals were analysed in the absence and presence of the DA uptake inhibitor nomifensine with the help of a mathematical(More)
In the present study the influence of intraventricular fetal mesencephalic grafts on the elimination rate of extracellular dopamine (DA) in the non-lesioned striatum of previously unilaterally 6-hydroxydopamine (6-OHDA) lesioned rats was investigated. The elimination of DA was measured after electrical stimulation of the medial forebrain bundle in vivo(More)
The effect of intraventricular fetal mesencephalic grafts placed in the previously 6-hydroxydopamine (6-OHDA) lesioned striatum on the kinetics of [3H]dopamine (DA) uptake into striatal synaptosomes prepared from the non-lesioned (contralateral) striatum was studied in rats. Using WIN 35,065 as specific [3H]DA uptake inhibitor, the equilibrium dissociation(More)
The present study employed fast cyclic voltammetry, at carbon-fibre microelectrodes, to monitor and compare the rate of dopamine uptake in the rat striatum contralateral to (a) the 6-hydroxydopamine (6-OHDA)-lesioned/grafted striatum and (b) the 6-OHDA-lesioned/ sham grafted striatum. Cell suspensions of foetal rat ventral mesencephalic tissue were grafted(More)
