Abstract Perception is subjective. Even basic judgments, like those of visual object size, vary substantially between observers and also across the field within same observer. The way in which system determines size objects remains unclear, however. We hypothesize that inferred from neuronal population activity V1 predict idiosyncrasies cortical functional architecture should therefore explain individual differences judgments. Here we show results novel behavioural methods magnetic resonance...

Between-group variability in socioeconomic status (SES) has been identified as a potentially important contributory factor studies reporting cognitive advantages bilinguals over monolinguals (the so called "bilingual advantage"). The present study addresses the potential importance of this alternative explanatory variable low and high SES bilingual monolingual performance on Simon task Tower London (TOL) task. Results indicated an overall response time advantage task, despite equivalent...

Recent evidence has challenged long-standing claims that multi-language acquisition confers long-term advantages in executive function and may protect against age-related cognitive deterioration. We assessed for a bilingual advantage older monolingual residents matched on age, gender, socioeconomic status. A comprehensive battery of tests was administered to measure non-verbal reasoning, working memory capacity, visuo-spatial memory, response inhibition, problem solving, language...

To our knowledge, no studies have examined lived experience ward environment nursing night. does paper add existing knowledge? The main complaint from was constant interruption their sleep, most in this study were observed 2–4 times an hour. Their sleep interrupted by (a) light torches shone into...

How we perceive the environment is not stable and seamless. Recent studies found that how a person qualitatively experiences even simple visual stimuli varies dramatically across different locations in field. Here use method developed recently call multiple alternatives perceptual search (MAPS) for efficiently mapping such biases several locations. This procedure reliably quantifies spatial pattern of also uncertainty choice. We show these measurements are strongly correlated with those from...

Background: Viral myocarditis is an important cause of heart failure and sudden cardiac death in young adults. Our previous studies have shown that many microRNAs are differentially expressed the during viral myocarditis, including microRNA-221 -222. Therefore we aimed at studying biological role these miRs mice, induced by human Coxsackie B3 virus.

MicroRNAs (miRs) are small non-coding RNAs implicated in fundamental disease processes such as inflammation and immunity by posttranscriptional downregulation of gene expression. Cardiac transplantation (HTX) is a life-saving intervention for end-stage heart failure. Despite contemporary immunosuppressants, acute rejection following HTX occurs up to 50% patients associated with decreased long-term survival. In this study, we aimed list show the therapeutic potential differentially expressed...

Duchenne muscular dystrophy (DMD), an X-linked childhood-onset caused by loss of the protein dystrophin, can be associated with neurodevelopmental, emotional and behavioural problems. A DMD mouse model also displays a neuropsychiatric phenotype, including increased startle responses to threat which normalise when dystrophin is restored in brain. We hypothesised that may humans DMD, would have potential translational therapeutic implications. To investigate this, we first designed novel...
