Besides targeting amyloid or tau metabolisms, regulation of redox metal ions is a recognized therapeutic target for Alzheimer's disease (AD). Based on the bioinorganic chemistry of copper, we designed specific chelators of copper(II) (TDMQs) insight to regulate copper homeostasis in the brain and to inhibit the deleterious oxidative stress catalyzed by copper-amyloid complexes. An oral treatment by TDMQ20 was able to fully reverse the cognitive and behavioral impairment in three different murine models, two nontransgenic models mimicking the early stage of AD and a transgenic model representing a more advanced stage of AD...

Several studies showed that shifting of visuospatial attention modulates sensory processing at multiple levels of the visual pathways and beyond, including the occipital striate cortices level. However, inconsistent findings have been reported thus leaving these issues still disputed. 21 participants took part to the present study (the EEG signals of 4 of them were discarded due to artifacts). We used ERPs and their neural sources to investigate whether shifting spatial attention in space across the horizontal meridian of the visual field affected striate cortices activation at the earliest latency...

How cognitive neural systems process information is largely unknown, in part because of how difficult it is to accurately follow the flow of information from sensors via neurons to actuators. Measuring the flow of information is different from measuring correlations between firing neurons, for which several measures are available, foremost among them the Shannon information, which is an undirected measure. Several information-theoretic notions of "directed information" have been used to successfully detect the flow of information in some systems, in particular in the neuroscience community...

Some reports have described that a high fructose diet is associated with a deficit of hippocampus-dependent cognitive functions. In this study, we have evaluated the effects of fructose on spatial memory and molecular markers in the hippocampus and prefrontal cortex and analyzed whether those alterations are reversible. Male Wistar rats ( n  = 60) began their treatment during adolescence. A group was forced to drink a solution of 10% fructose for twelve weeks. Another group was subjected to the same fructose intake schedule, but later fructose was removed, and tap water was provided for four weeks...

Anomalous self-experiences (ASEs) are prevalent in schizophrenia, but its underpinnings are not completely understood. Given the likely complex substrate of the experience of the self, neurocognitive functions requiring coordinate cerebral activity may relate to ASEs. Moreover, cognitive deficits functioning may be involved in the link between self-experience disturbances and some aspects of social dysfunction in schizophrenia. We have assessed ASEs in 41 schizophrenia patients (11 first episodes) using the Inventory of Psychotic-Like Anomalous Self-Experiences (IPASE), and the general cognition using the Brief Assessment of Cognition in Schizophrenia (BACS)...

SCOPE: Alzheimer's disease (AD) is characterized by amyloid-β (Aβ) related imbalance, tau-hyperphosphorylation, and neuroinflammation, in which Aβ and neuroinflammation could induce brain insulin resistance (IR). Gut microbiome disorder is correlated with inflammation in AD. As of yet, there are no effective treatments clinically. Thus, we focus on the potential benefit of quercetin-3-O-glucuronide (Q3G), a pharmacologically active flavonol glucuronide, on AD treatment by regulating brain IR and the gut microbiome...
