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 […]

New drug combination shows promise for common pediatric brain tumor: Everolimus, carboplatin together slow low-grade glioma tumor growth, reduce tumor size

A new combination treatment aimed at resistant and recurrent low-grade gliomas slowed tumor growth and killed tumor cells in laboratory and mouse models. Researchers at the Johns Hopkins Kimmel Cancer Center and the Johns Hopkins University School of Medicine combined carboplatin, a standard chemotherapy drug that works well against these brain tumors, and everolimus, which […]

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 […]

Voluntary control of brainwaves in deep brain of patients with Parkinson’s disease

Parkinson’s disease is associated with abnormal beta wave activity in the subthalamic nucleus (STN), but a direct connection between this activity and movement difficulties has not yet been established. A study group at Osaka University developed a neurofeedback system which enables patients with Parkinson’s disease to voluntarily control beta wave activity in their deep brain […]
