New stem-cell based stroke treatment repairs damaged brain tissue

Researchers have developed a new treatment for stroke that reduces brain damage and accelerates the brain’s natural healing tendencies in animal models.

Fast-acting, readily available gas may mitigate blast-induced brain injury

The inert gas has been used for the first time to try and reduce the impact of traumatic brain injuries (TBI) caused by blasts such as those in conflict zones and terror attacks.

Poor fitness linked to weaker brain fiber, higher dementia risk

Scientists have more evidence that exercise improves brain health and could be a lifesaving ingredient that prevents Alzheimer’s disease.

Understanding brain functions using upconversion nanoparticles

Scientists have developed a novel approach for deep brain stimulation. The new method utilizes upconversion nanoparticles to allow delivery of visible light deep into the brain to stimulate neural activities in a less-invasive manner. This innovation m…

Can’t get an image out of your head? Your eyes are helping to keep it there.

Through brain imaging, scientists have found evidence that the brain uses eye movements to help people recall vivid moments from the past, paving the way for the development of visual tests that could alert doctors earlier about those at risk for neuro…
