Weekly Neuroscience Update

You probably know that walking does your body good, but it’s not just your heart and muscles that benefit. Researchers found that the foot’s impact during walking sends pressure waves through the arteries that significantly modify and can increase the supply of blood to the brain.

An international collaboration of neuroscientists has shed light on how the brain helps us to predict what is coming next in speech.

A recently published study, which combines four studies of extreme longevity, has identified new rare variants in chromosomes 4 and 7 associated with extreme survival and with reduced risks for cardiovascular and Alzheimer’s disease.

Scientists have discovered that neurons in brain regions that store memory can form networks in the absence of synaptic activity.

A new study reports estrogen fluctuations can alter brain circuit activation in women with a variant of a specific gene.

Your brain may not be the same age as your body, and an “older” brain may be linked to an increased risk of dying at a younger age, a new study finds.

Zapping the brain with just a bit of electricity at the right time may help to improve memory function in some people, according to a new study.

Gentle noise stimulation can enhance sleep quality and improve memory in older people, a new study reports.

Like air-traffic controllers scrambling to reconnect flights when a major hub goes down, the brain has a remarkable ability to rewire itself after suffering an injury. However, maintaining these new connections between brain regions can strain the brain’s resources, which can lead to serious problems later, including Alzheimer’s Disease, according to researchers.

Researchers have discovered a new cellular mechanism that may be a root cause of multiple sclerosis.

Combining brain training programs with transcranial direct current simulation can lead to cognitive improvements and better working memory, a new study reports.

Finally this week, a new video game is helping to speed up neuroscience research by allowing players to reconstruct the architecture of neurons.
