Researchers discover the Achilles’ heel of an aggressive brain cancer: Could antihistamine be a potential aid in defeating cancerous cells?

Glioblastoma is the most prevalent and also the most lethal type of brain tumour in adults, with no curative treatment currently available. Glioblastomas cannot be surgically completely excised, as the tumour cells are adept at invading tissues and spreading around the brain. In addition, glioblastoma cells are extremely resistant to existing drug therapies. For a […]

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 […]

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 […]

Using an anti-smoking drug to control neurons

An anti-smoking drug now has a new job — as a chemical switch to turn select neurons on or off. The drug latches on to designer proteins, called ion channels, that control whether or not a neuron will send a message. By putting those proteins only in certain groups of neurons, scientists can target modulation […]
