BackgroundTranscranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex (DLPFC) hypothetically modulates cognitive functions by facilitating or inhibiting neuronal activities chiefly in cerebral cortex. The effect of tDCS deeper brain region, basal ganglia-cortical circuit, remains unknown.ObjectiveTo investigate interaction between ?-aminobutyric acid (GABA) concentratio...

Sujetos Método: Estudio transversal incluyó 355 entre 15 a 19 a...

g -aminobutiric acid (gaba), the major inhibitory neurotransmitter in the central nervous system has two major receptor subtypes (gabaa and gabab). gabab receptors are activated by the antispastic and muscle relaxant agent, baclofen, which is a lipophilic derivative of gaba. since 1962 several strategies have been reported for the synthesis of baclofen.in this study an approach has been made to...

spreading depression (sd), discovered by leao in 1944, is a pathophysiological wave which propagates slowly in the brain (3 mm/min) and cause dramatic ionic and hemodynamic changes. sd appears to act through several mechanisms and receptors which have not completely understood. here, we studied the effect of inhibitory system in animal model of sd using immunohistochemistry technique. after imp...

1) chronic administration of morphine hydrochloride in the drinking water of mice induced physical dependence. jumping and diarrhea, two signs of withdrawal, were produced by intraperitoneal (ip) injection of naloxone. 2) baclofen, bicuculline and picrotoxin decreased the number of mice's jumping episodes and frequency of diarrhea. 3) muscimol decreased jumping but not diarrhea. 4) the data ind...

The cold-sensitive peach fruits are prone to chilling injury (CI). ?-aminobutyric acid (GABA) has been confirmed effectively improve peaches’ cold tolerance. This research aimed probe the role of dynamic changes in membrane lipid metabolism GABA-mediated tolerance and reveal underlying mechanisms based on metabolomics. GABA treatment improved by reducing phosphatidic (PA) accumulation via inhib...

Gamma aminobutyric acid (GABA) is one of the inhibitory neurotransmitters that may have the ability torelieve the intensity of stress. Heat stress remains a major threat for duck production in summer in most areas of China. The current study was conducted to investigate the effect of dietary GABA on performanceparameters and plasma metabolites of heat exposed ducks. Two thousand Cherry Valley d...

Several studies have demonstrated that nitric oxide (NO) is involved in hyperalgesia induced by NMDA activity in Morphine tolerance and NO synthase inhibitors can attenuate hyperalgesia in morphine tolerance. In addition, one of the possible mechanisms in morphine tolerance is reduction of GABA inhibitory effect. For this reason, we used GABA agonists (muscimol and baclofen) to investigate the ...

GABA (γ-amino-butylic acid)-mediated inhibition in the dendrites of CA1 pyramidal neurons was characterized by two-photon uncaging of a caged-GABA compound, BCMACM-GABA, and one-photon uncaging of RuBi-GABA in rat hippocampal slice preparations. Although we found that GABA(A)-mediated currents were diffusely distributed along the dendrites, currents elicited at the branch points of the apical d...
