Recent literature on human cognitive activity enhancement is reviewed and summarized. Two classes of pharmacological approaches are picked out, i.e. modern aspects of traditional substance utilization and application of specially developed drugs. Among non-pharmacological approaches a number of psychological, physiological, behavioral and biophysical methods to improve human cognition, memory and learning are analyzed. The most attention is paid to non-drug approaches that utilize bioelectric processes of the individual including characteristics of its brain electrical activity--electroencephalogram (EEG) to enhance different aspects of cognitive functioning. Some promising lines of these investigations are delineated.

The brain undergoes atrophy and cognitive decline with advancing age. The utilization of brain age prediction represents a pioneering methodology in the examination of brain aging. This study aims to develop a deep learning model with high predictive accuracy and interpretability for brain age prediction tasks.

Extrinsic motivation can foster effortful cognitive control. Moreover, the selective coupling of extrinsic motivation on low- versus high-control demands tasks would exert an additional impact. However, to what extent their influences are further modulated by the level of Need for Cognition (NFC) remains unclear.

While impaired response inhibition has been reported in attention-deficit/hyperactivity disorder (ADHD), findings in disruptive behavior disorders (DBDs) have been inconsistent, probably due to unaccounted effects of co-occurring ADHD in DBD. This study investigated the associations of behavioral and neural correlates of response inhibition with DBD and ADHD symptom severity, covarying for each other in a dimensional approach. Functional magnetic resonance imaging data were available for 35 children and adolescents with DBDs (8-18 years old, 19 males), and 31 age-matched unaffected controls (18 males) while performing a performance-adjusted stop-signal task.

Rheumatoid arthritis (RA) is a chronic autoimmune disease marked by systemic inflammation. While RA primarily affects the joints, its systemic effects may lead to an increased cerebro- and cardiovascular risk. Atherosclerosis of the carotid arteries is a significant risk factor for cerebrovascular events and serves as a surrogate marker for cardiovascular risk.

Down syndrome (DS) is strongly associated with Alzheimer's disease (AD) due to APP overexpression, exhibiting Amyloid-β (Aβ) and Tau pathology similar to early-onset (EOAD) and late-onset AD (LOAD). We evaluated the Aβ plaque proteome of DS, EOAD, and LOAD using unbiased localized proteomics on post-mortem paraffin-embedded tissues from four cohorts (n = 20/group): DS (59.8 ± 4.
