The primate striatum has a compartmental organization reflected both in the topography of its afferent projections and in the segregation of its morphologically similar but neurochemically distinct efferent neurons. Discretely projecting mesostriatal neurons release dopamine (DA) which modulates the responses of striatal neurons to other afferent inputs.(More)
The spectra of pharmacological effects of ethanol and the benzodiazepine show a degree of overlap. Neurophysiological and neurochemical evidence indicates that both ethanol and benzodiazepines facilitate inhibitory neurotransmission mediated by GABA. Diazepam has been reported to inhibit both the tremor and mechanism of cerebellar cyclic GMP caused by(More)
MK-801 (5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine maleate) is a novel anticonvulsant agent reported to antagonize certain N-methyl-D-aspartate (NMDA)-mediated effects non-competitively. The question arises of the mechanism underlying the anti-NMDA and anticonvulsant effects of MK-801. In the present study MK-801 is shown to be an(More)
A technique permitting the serial determination of plasma ethanol concentration (PEC) in mice is described. Samples of blood, 5 microliters in volume, are drawn from the infraorbital plexus. It was demonstrated that this source reflects the rapid dynamics of absorption and clearance after an intraperitoneal injection of ethanol. Samples taken from the tail(More)
