abstract injection of sulpiride (d2 receptor antagonist, antipsychotic drug) into vmn hypothalamus, increased gastric volume secretion and decreased gastric ph. the present study the effect of sch23390 (d1 dopamine receptor antagonist) on the gastric acid secretion and its acidity were studied. 70 rats were divided into 7 groups: two control groups, two sham groups given medicine solvents, a sc...
Mitochondria are considered major generators of cellular reactive oxygen species (ROS) which are implicated in the pathogenesis of neurodegenerative diseases such as Parkinson's disease (PD). We have recently shown that isolated mitochondria consume hydrogen peroxide (H₂O₂) in a substrate- and respiration-dependent manner predominantly via the thioredoxin/peroxiredoxin (Trx/Prx) system. The goa...
The midbrain dopaminergic system is a key element in the control of motor activity, cognition, and the motivational effects of drugs of abuse, including nicotine. In this issue of Neuron, Drenan et al. find that alpha6-containing nicotinic acetylcholine receptors might selectively activate mesolimbic and mesostriatal dopaminergic neurons, enhancing striatal dopamine release and its behavioral c...
Chronic use of cocaine is associated with a reduced density of dopaminergic D2 receptors in the striatum, with negative consequences for cognitive control processes. Increasing evidence suggests that cognitive control is also affected in recreational cocaine consumers. This study aimed at linking these observations to dopaminergic malfunction by studying the spontaneous eyeblink rate (EBR), a m...
