Researchers identify gene involved in neuronal vulnerability in Alzheimer’s disease

Early stages of neurodegenerative disorders are characterized by the accumulation of proteins in discrete populations of brain cells and degeneration of these cells. For most diseases, this selective vulnerability pattern is unexplained, yet it could y…

Shared blueprint in brain development across different functional areas

Researchers have investigated brain development to understand how different areas of the brain become specialized in handling information such as vision, sound, touch and planning.

Brain waves travel in one direction when memories are made and the opposite when recalled

These wide-ranging waves quickly link the specific constellations of brain regions that work in harmony to perform a task.

Lack of focus doesn’t equal lack of intelligence — it’s proof of an intricate brain

Imagine a busy restaurant: dishes clattering, music playing, people talking loudly over one another. It’s a wonder that anyone in that kind of environment can focus enough to have a conversation. A new study provides some of the most detailed insights …

How the brain coordinates speaking and breathing

Researchers discovered a brain circuit that drives vocalization and ensures that you talk only when you breathe out, and stop talking when you breathe in. This circuit is under control of a brainstem region called the pre-B tzinger complex.

Does iron accumulate in brain after concussions?

People who have headaches after experiencing concussions may also be more likely to have higher levels of iron in areas of the brain, which is a sign of injury to brain cells, according to a preliminary study released today, March 5, 2024, that will be…

Virtual reality exposure plus electric brain stimulation offers a promising treatment for PTSD

Combining two treatments could be a promising option for people, especially military veterans, whose lives are negatively affected by post-traumatic stress disorder, finds a new study. In a clinical trial conducted among U.S. military veterans, partici…

A noninvasive treatment for ‘chemo brain’

A noninvasive treatment may help to counter ‘chemo brain’ impairment often seen in chemotherapy patients: Exposure to light and sound with a frequency of 40 hertz protected brain cells from chemotherapy-induced damage in mice, researchers found.

New microscopy tech answers fundamental questions

A new tool captures data from an unprecedented 1 million neurons simultaneously, painting a much fuller picture of brain dynamics.

Opening a window on the brain

Researchers have introduced a new method for in vivo brain imaging, enabling large-scale and long-term observation of neuronal structures and activities in awake mice. This method is called the ‘nanosheet incorporated into light-curable resin’ (NIRE) m…
