How our brain generates consciousness — and loses it

Medically-induced loss of consciousness (mLOC) during anesthesia is associated with a break-down of brain connectivity at the anatomical macro scale — across cortical areas — yet what role brain micro circuitry plays in LOC remains unclear. How does our brain generate our consciousness? And why do we lose it during anesthesia? Influential theories suggest that […]

How the brain integrates sensory input

Researchers from Bielefeld University, Oxford University (Great Britain), and Aix-Marseille University (France) investigated this phenomenon of flexibility in perception, and have now published a study on their findings that appears in the scientific journal Neuron (29 April 2019). In their publication, the researchers reveal where sensory stimuli are integrated in the brain, and in which […]

Exercise activates memory neural networks in older adults: Study shows acute exercise has the ability to impact brain regions important to memory

How quickly do we experience the benefits of exercise? A new University of Maryland study of healthy older adults shows that just one session of exercise increased activation in the brain circuits associated with memory — including the hippocampus — which shrinks with age and is the brain region attacked first in Alzheimer’s disease. “While […]

Light, physical activity reduces brain aging

Incremental physical activity, even at light intensity, is associated with larger brain volume and healthy brain aging. Considerable evidence suggests that engaging in regular physical activity may prevent cognitive decline and dementia. Active individuals have lower metabolic and vascular risk factors and these risk factors may explain their propensity for healthy brain aging. However, the […]

Digital device overload linked to obesity risk

If your attention gets diverted in different directions by smartphones and other digital devices, take note: Media multitasking has now been linked to obesity. New research from Rice University indicates that mindless switching between digital devices is associated with increased susceptibility to food temptations and lack of self-control, which may result in weight gain. “Increased […]

Quick thinking? It’s all down to timing: New insights into neuronal behavior in the brain may pave way to identifying learning disabilities

Remember hearing people being called slow learners by teachers and parents? That oft-used description of someone who takes a wee bit longer to process information, now has a scientific basis for its existence. Scientists from the NUS Yong Loo Lin School of Medicine have found that the rapidity with which a person is able to […]
