The aim of the present study was to gain insight into the neurobiological processes, particularly the dopaminergic processes, underlying attentional control during reading and reading comprehension. In order to test the effects of increased levels of dopamine (DA) in the brain, female university ...

These motor disturbances correlate with reduced dopamine (DA) levels, increased DA turnover, synaptic terminal loss, and notably, the depletion of dopaminergic neurons in the substantia nigra and noradrenergic neurons in the locus coeruleus. Furthermore, P8 α-SynTg mice exhibit alterations in gut ...
Determined by HPLC with electrochemical detector, the levels of dopamine and 5-hydroxytryptamine in whole fetal brain were not remarkably altered by ethanol treatment, while the levels of homovanillic acid and 5-hydroxyindole acetic acid in high dose (4.0 g/kg) of ethanol-treated rats were ...
The selective activation of the prefrontal cortical dopamine system by mild stress can be mimicked by anxiogenic β -carbolines such as FG7142. To investigate the functional relevance of elevated levels of dopamine turnover in the prefrontal cortex, the current study examined the effects of FG7142...
No similar changes were found in the intact hemisphere or in the ventral striatum of the dopamine depleted hemisphere. The lesioning of the dopamine innervation to the striatum was confirmed by a strongly reduced dopamine transporter binding in the striatum, indicating an abundant loss of dopamine ...
Taken together, this evidence led us to hypothesize that negative affective withdrawal behaviors are triggered by declining levels of dopamine in structures downstream of the VTA. The current studies address this hypothesis by examining the contribution of dopaminergic signaling in these structures to ...
Which statement is TRUE about nicotine and smoking? \\ a. Nicotine is far less addictive than it was once thought to be. b. Nicotine elevates levels of dopamine, producing pleasure. c. Most adult smokers started smoking after the age of 21. ...
Increased L-DOPA-derived dopamine following selective MAO-A or -B inhibition in rat striatum depleted of dopaminergic and serotonergic innervation. Br J Pharmacol 2013;170:999-1013.O. Sader-Mazbar, Y. Loboda, M. J. Rabey, and J. P. Finberg, "Increased L-DOPA-derived dopamine following ...
Whilst an unfamiliar tone had no measurable effect on extracellular dopamine levels, the same tone which had previously been paired with footshock evoked a significant increase in dopamine during the tone presentation, indicating that it is the aversive nature of the stimulus onset rather than the ...
