Abstract Background In the central nervous system of mammals, transporters localized on presynaptic nerve terminals regulate reuptake neurotransmitters. These are selective for a specific neurotransmitter such as dopamine (DA) and norepinephrine (NE). Specifically in synapse, transporter (DAT) reuptakes DA (NET) NE. However previous research has found that avian species do not have gene DAT, th...

Reinforcement learning theory has generated substantial interest in neurobiology, particularly because of the resemblance between phasic dopamine and reward prediction errors. Actor-critic theories have been adapted to account for the functions of the striatum, with parts of the dorsal striatum equated to the actor. Here, we specifically test whether the human dorsal striatum--as predicted by a...

BACKGROUND The food addiction model proposes that obesity overlaps with addiction in terms of neurobiological alterations in the striatum and related clinical manifestations (i.e., craving and persistence of unhealthy habits). Therefore, we aimed to examine the functional connectivity of the striatum in excess-weight versus normal-weight subjects and to determine the extent of the association b...

Background. the basal ganglia’s circuit dysfunction has a major role in a range of movement disorders. Some evidence has shown that exercise can improve performance, especially locomotor activity after brain injuries. There was currently insufficient information to define the impacts of intensity, duration, and frequency of different exercises. Objectives. in this study, we examine the r...

Corynebacterium striatum (C striatum) has been considered a contaminant of blood culture in past decades. Here we report the case of a patient with acute deterioration of chronic renal failure. She received hemodialysis and died from C striatum bacteremia. By using a randomly amplified polymorphic DNA (RAPD) method, we found that an association existed between C striatum from the bloodstream an...

The striatum is critical for learning and decision making; however, the molecular mechanisms that govern striatum function are not fully understood. The extracellular signal regulated kinase (ERK) cascade is an important signaling pathway that underlies synaptic plasticity, cellular excitability, learning and arousal. This review focuses on the role of ERK signaling in striatum function. ERK is...

The striatum is connected to the cerebral cortex through multiple anatomical loops that process sensory, limbic, and heteromodal information. Tract-tracing studies in the monkey reveal that these corticostriatal connections form stereotyped patterns in the striatum. Here the organization of the striatum was explored in the human with resting-state functional connectivity MRI (fcMRI). Data from ...

introduiction: this study aimed to investigate the protective effects of 12-week voluntary exercise using a running wheel on the striatum  dopaminergic neurons against 6-hydroxydopamine lesions in rats. materials and method: twenty five rats were divided into three groups including healthy, parkinson and training-parkinson. the training groups were housed in individual cages geared with running...

The function of striatopallidal neurons is regulated by N-methyl-D-aspartate (NMDA) and dopamine D2 receptors. Previous studies show that immediate early gene induction by D2 receptor blockade is suppressed by NMDA receptor antagonists. Because the pharmacology of NMDA receptors depends on the incorporation of different NR2 subunits and NR2 subunits show regional and cellular differences in the...

Background: Central renin angiotensin system has an important role on the cerebral microcirculation and metabolism. Our previous work showed that inhibition of angiotensin converting enzyme (ACE) activity prior to induction of ischemia protected the brain from severe ischemia/reperfusion (I/R) injuries. This study evaluated the impacts of post-ischemic inhibition of ACE, enalapril, on brain inf...
