Learning a new motor skill involves multiple cognitive aspects such as attention, planning, prioritizing, execution, and error correction. In current study, we examined whether the students opted for pure mathematics at their undergraduate level have enhanced motor skills as compared to those pursuing biological sciences at the same level of education. A total of twenty subjects participated in a visuomotor adaptation task. The results showed that the overall movement related errors in subjects with mathematics background were lower than the biosciences students (p = 0...

Gamma oscillations emerge generally in working memory to aspect of higher cognitive functions, and typically with the interaction of brain network. How is gamma oscillatory activity influenced by the functional connection in the brain'a network? How can gamma oscillations be increased by neural modulation to result in potential benefits for working memory? The present study aims to investigate the intensity of gamma oscillations modulated by low frequency repetitive transcranial magnetic stimulation (rTMS), and the possible brain network mechanism of increased gamma oscillations during working memory task in rats...

We tested the hypothesis that exposure of glut3+/- mice to a ketogenic diet ameliorates autism-like features which includes aberrant behavior and electrographic seizures. We first investigated the life course sex-specific changes in basal plasma-CSF-brain metabolic profile, brain glucose transport/uptake, glucose and monocarboxylate transporter proteins, and ATP in the presence or absence of systemic insulin administration. Glut3+/- male but not female mice (5m of age) displayed reduced CSF glucose/lactate concentrations with no change in brain Glut1, Mct2, glucose uptake or ATP...

BACKGROUND: Potentially modifiable lifestyle factors may influence cognitive health in later life and offer potential to reduce the risk of cognitive decline and dementia. The concept of cognitive reserve has been proposed as a mechanism to explain individual differences in rates of cognitive decline, but its potential role as a mediating pathway has seldom been explored using data from large epidemiological studies. We explored the mediating effect of cognitive reserve on the cross-sectional association between lifestyle factors and cognitive function in later life using data from a population-based cohort of healthy older people...

OBJECTIVE: Mindfulness meditation training has been previously shown to enhance behavioral measures of executive control (e.g. attention, working memory, cognitive control), but the neural mechanisms underlying these improvements are largely unknown. Here, we test whether mindfulness training interventions foster executive control by strengthening functional connections between dorsolateral prefrontal cortex (dlPFC) - a hub of the executive control network - and frontoparietal regions that coordinate executive function...

Ying Yang Bao (YYB), a complementary food supplement, has helped to rapidly improve the nutrition status of infants and young children in poor rural regions in China. The first YYB study was performed in 2001 by the International Life Sciences Institute, the Chinese Centers for Disease Control and Prevention, and Nestlé. In 2008, the establishment of national standards for complementary food supplements stimulated implementation of about 15 nutrition intervention projects in poor rural counties in which YYB was applied to infants and young children as home fortification for complementary feeding...

Neuronal damage and axonal regeneration inhibition are the main reasons to poor functional recovery after ischemia. Nogo-A signals inhibit axon outgrowth through the PirB receptor after ischemic reperfusion injury in central nervous system. We use TAT-PEP, a novel protein which could pass through the blood brain barrier, to block the function of PirB and identify the long-term neurological and behavioral recovery after bilateral common carotid artery occlusion (BCCAO) in mice. We observed that TAT-PEP promoted neuron survival and inhibited neuronal apoptosis...

Many drugs with unknown safety profiles are administered to pregnant women, placing their offspring at risk. I assessed whether behavioral outcomes for children exposed during gestation to antidepressants, anxiolytics, anti-seizure, anti-nausea and sedative medications can be predicted by more extensive animal studies than are part of the FDA approval process. Human plus rodent data were available for only 8 of 33 CNS-active drugs examined. Similar behavioral and cognitive deficits, including autism and ADHD emerged in human offspring and in animal models of these disorders after exposure to fluoxetine, valproic acid, carbamazepine, phenytoin, phenobarbital, acetaminophen and ibuprofen...

S 38093, a novel histamine H3 receptor inverse agonist, was tested in a series of neurochemical and behavioral paradigms designed to evaluate its procognitive and arousal properties. In intracerebral microdialysis studies performed in rats, S 38093 dose-dependently increased histamine extracellular levels in the prefrontal cortex and facilitated cholinergic transmission in the prefrontal cortex and hippocampus of rats after acute and chronic administration (10mg/kg i.p.). Acute oral administration of S 38093 at 0...

BACKGROUND: Neurodegenerative disorders, such as deficits in learning, memory and cognition and Alzheimer's disease are associated with diabetes mellitus. Brain-derived neurotrophic factor (BDNF) is a neurotrophic factor and is known to possess anti-obesity, anti-diabetic actions and is believed to have a role in memory and Alzheimer's disease. OBJECTIVE: To investigate whether STZ can reduce BDNF production by rat insulinoma (RIN5F) cells in vitro and decrease BDNF levels in the pancreas, liver and brain in vivo...

We measured changes in self and friend biases in perceptual matching in young and older participants. Participants learned associations between neutral geometric shapes and three personal labels (You, Friend, or Stranger), representing themselves, their named best friend, and a stranger not corresponding to anyone they knew. They then responded whether the shapes and labels matched or mismatched. In addition, participants reported the perceived personal distance between themselves, their best friend, and a stranger...

BACKGROUND: Effective interventions are needed to improve brain function in mild cognitive impairment (MCI), an early stage of Alzheimer's disease (AD). The posterior cingulate cortex (PCC)/precuneus is a hub of the default mode network (DMN) and is preferentially vulnerable to disruption of functional connectivity in MCI and AD. OBJECTIVE: We investigated whether 12 weeks of aerobic exercise could enhance functional connectivity of the PCC/precuneus in MCI and healthy elders...

Epidemiological studies implicate diets rich in saturated free fatty acids (sFFA) as a potential risk factor for developing Alzheimer's disease (AD). In particular, high plasma levels of the sFFA palmitic acid (palmitate) were shown to inversely correlate with cognitive function. However, the cellular mechanisms by which sFFA may increase the risk for AD are not well known. Endoplasmic reticulum (ER) stress has emerged as one of the signaling pathways initiating and fostering the neurodegenerative changes in AD by increasing the aspartyl protease β-site AβPP cleaving enzyme 1 (BACE1) and amyloid-β (Aβ) genesis...

Juri-Alexander Witt, Christoph Helmstaedter
Antiepileptic pharmacotherapy can have a negative or positive impact on cognition and behavior. Besides individual susceptibilities (in terms of idiosyncratic reactions), the risk of adverse drug effects largely depends on treatment decisions. Therefore practical strategies to prevent neuropsychological side effects comprise (1.) selecting antiepileptic drugs (AEDs) with superior neuropsychological side effect profiles, (2.) restricting the individual drug load (target doses and number of concurrent AEDs), (3...

There are volumes of information available to process in visual scenes. Visual spatial attention is a critically important selection mechanism that prevents these volumes from overwhelming our visual system's limited-capacity processing resources. We were interested in understanding the effect of the size of the attended area on visual perception. The prevailing model of attended-region size across cognition, perception, and neuroscience is the zoom-lens model. This model stipulates that the magnitude of perceptual processing enhancement is inversely related to the size of the attended region, such that a narrow attended-region facilitates greater perceptual enhancement than a wider region...

Sleep spindles and K-complexes are among the most prominent micro-events observed in electroencephalographic (EEG) recordings during sleep. These EEG microstructures are thought to be hallmarks of sleep-related cognitive processes. Although tedious and time-consuming, their identification and quantification is important for sleep studies in both healthy subjects and patients with sleep disorders. Therefore, procedures for automatic detection of spindles and K-complexes could provide valuable assistance to researchers and clinicians in the field...

Massive Multiple Online Role-Playing Games (MMORPGs) have increased in popularity among children, juveniles, and adults since MMORPGs' appearance in this digital age. MMORPGs can be applied to enhancing language learning, which is drawing researchers' attention from different fields and many studies have validated MMORPGs' positive effect on language learning. However, there are few studies on the underlying behavioral or neural mechanism of such effect. This paper reviews the educational application of the MMORPGs based on relevant macroscopic and microscopic studies, showing that gamers' overall language proficiency or some specific language skills can be enhanced by real-time online interaction with peers and game narratives or instructions embedded in the MMORPGs...
