Typical cognitive load tasks are now known to deactivate the brain’s default-mode network (DMN). This raises the possibility that apparent effects of cognitive load could arise from disruptions of DMN processes, including social cognition. Cognitive load studies are reconsidered, with reinterpretations of past research and implications for dual-process theory. Read Full Article (External Site) Dr. […]

Amyloid-β (Aβ) deposition, neurofibrillary tangles induced by phosphorylation of tau protein and neuronal apoptosis are pathological hallmarks of Alzheimer’s disease (AD).The dementia rate in the alcoholic abusers were found to be higher than the control people. The present study explored potential roles of alcohol dehydrogenase 1B (ADH1B) in AD pathological process.The results showed that ADH1B […]

Many cognitive abilities decline with age even in the absence of detectable pathology. Recent evidence indicates that age-related neural dedifferentiation, operationalized in terms of neural selectivity, may contribute to this decline. We review here work exploring the relationship between neural dedifferentiation, cognition, and age. Compelling evidence for age effects on neural selectivity comes from both […]
