The influence of micronutrients
There has been much media speculation (often sensationalist and conflicting) regarding the potential influence of micronutrients on cognitive function and performance. Our aim was to identify the micronutrients specifically implicated in cognitive function and to review the literature to identify original sources underlying the media coverage.
The neuro- and psychophysiological effects of bromantane
Abstract The study of EEG and psychophysiological parameters and their correlations in 10 healthy volunteers after single oral administration of bromantan in comparison with placebo revealed favourable influence of the drug on operators' functional state. By EEG-profile (increase in middle-frequency alpha-rhythm power with lowering of powers in delta- and beta1-bands) bromantan is similar to many drugs with moderate psychostimulating,...
The phenotropil treatment of the consequences of brain organic lesions
Ninety-nine patients with encephalopathy developed in the remote period after acute lesions of cerebral blood circulation, brain traumas and cerebral gliomas surgery have been studied. Phenotropil was used in a dosage of 200 mg per day during one month. A CT survey revealed that in a stable state of brain changes phenotropil exerted the mostly pronounced influence on movement...
The prolongation of the lifespan of rats by repeated oral administration of [60]fullerene
Countless studies showed that [60]fullerene (C60) and derivatives could have many potential biomedical applications. However, while several independent research groups showed that C60 has no acute or sub-acute toxicity in various experimental models, more than 25 years after its discovery the in vivo fate and the chronic effects of this fullerene remain unknown. If the potential of C60 and...
The relationship between n-back performance and matrix reasoning — implications for training and transfer
Abstract: We have previously demonstrated that training on a dual n-back task results in improvements in fluid intelligence (Gf) as measured by matrix reasoning tasks. Here, we explored the underlying mechanisms of this transfer effect in two studies, and we evaluated the transfer potential of a single n-back task. In the first study, we demonstrated that dual and single...
The role of GABA in anxiety disorders
Abstract Anxiety stems from and perpetuates dysregulation of neurobiological systems, but the exact mechanisms of anxiety disorders are still only partially understood. Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter known to counterbalance the action of the excitatory neurotransmitter glutamate. Several pharmacologic agents target the GABA system and modulate the overall effect of GABA. This article highlights multiple neurobiological...
The testosterone mimetic properties of icariin
Abstract AIM: To evaluate the testosterone mimetic properties of icariin. METHODS: Forty-eight healthy male Sprague-Dawley rats at the age of 15 months were randomly divided into four groups with 12 rats each: the control group (C), the model group (M), the icariin group (ICA) and the testosterone group (T). The reproductive system was damaged by cyclophosphamide (intraperitoneal...
Towards better brain management
The learning and memory deficits have been recognized as severe and consistent neurological disorders associated with numerous neurodegenerative states. Research in this area has gained momentum only in the recent past after the biochemical and physiological basis of these processes have been understood.
Training the Emotional Brain: Improving Affective Control through Emotional Working Memory Training
Abstract Affective cognitive control capacity (e.g., the ability to regulate emotions or manipulate emotional material in the service of task goals) is associated with professional and interpersonal success. Impoverished affective control, by contrast, characterizes many neuropsychiatric disorders. Insights from neuroscience indicate that affective cognitive control relies on the same frontoparietal neural circuitry as working memory (WM) tasks, which suggests...
