Synaptic plasticity in the mesolimbic dopamine (DA) system is thought to contribute to the neural adaptations that mediate behavioral sensitization, a model for core aspects of addiction. Recently, it has been demonstrated that multiple classes of drugs of abuse, as well as acute stress, enhance strength at excitatory synapses on midbrain DA neurons. Here,(More)
High affinity uptake of D-[3H]aspartate, [3H]choline and [3H]GABA was examined in synaptosomal-containing preparations of rat nucleus accumbens septi 7 to 10 days after unilateral or bilateral N-methyl-D-aspartate lesions confined to the parataenial nucleus of the thalamus or the basolateral nucleus of the amygdala. Uptake of both D-[3H]aspartate and(More)
The present study has examined the influence of the central nucleus of the amygdala (Ce) and the basolateral nucleus of the amygdala (BL) on the baroreceptor heart rate (HR) reflex in conscious, unrestrained rats. Baroreceptor HR reflex activity was examined in rats with bilateral excitotoxin (N-methyl-D-aspartate; 40 nmol/side)-induced lesions of the Ce or(More)
Despite marked improvements in the interpretation of systematic relationships within Eutheria, particular nodes, including Paenungulata (Hyracoidea, Sirenia and Proboscidea), remain ambiguous. The combination of a rapid radiation, a deep divergence and an extensive morphological diversification has resulted in a limited phylogenetic signal confounding(More)
We present spectroscopic observations of a complete sub-sample of 13 low-luminosity radio galaxies selected from the 2Jy sample. The underlying continuum in these sources is carefully modelled in order to make a much-needed comparison between the emission line and continuum properties of FRIs with those of other classes of radio sources. We find that 5(More)
