analysis of catecholamine decline after tyrosine hydroxylase inhibition and metabolite/monoamine ratios , as indices for transmitter utilization rate , indicated an increased noradrenaline turnover in terminals spared by dsp 4 , while dopamine turnover appeared to be reduced in many regions ( i.a . cerebral cortex , striatum , accumbens , olfactory tubercle and spinal cord ) , most pronounced in cingulate cortex .
