Three prizes were awarded to six researchers working across the life sciences on cellular organization, protein structure, and the genetic underpinnings of a chronic sleep disorder.

The Middlebury College neuroscientist explores enzymes that affect brain cell development and neurodegeneration.

Low-intensity electrical stimulation allows older adults to better recall a list of words for at least a month following the treatment, a study finds, providing further evidence for the debated idea that electrical stimulation can enhance cognitive performance.

Maligned peptides such as the Alzheimer’s-associated amyloid precursor protein may have critical roles in the healthy brain.

The normal functions of peptides that aggregate in Alzheimer’s, Parkinson’s, and Huntington’s have been largely overlooked by scientists, but some argue that they are critical for understanding the development of disease.

Testing in animals and lab-grown cells suggests the experimental drug could enhance the function of lysosomes within cells.

Researchers report molecular evidence of traumatic brain injury in headbutting animals, but other experts aren’t convinced.

Research identifies 10 types of dopamine-making neurons, one of which seems to die off during the disease.

Niacin, a form of vitamin B3 used to treat cardiovascular disease, helps immune cells in the brain fight neurodegenerative diseases such as Alzheimer’s in mice models, according to recent studies. Researchers hope that human clinical trials will swiftly follow.

The patient, who has ALS, is able to communicate in complete sentences by deliberately altering his brain’s activity.

His work was pivotal to understanding the mechanisms of neurodegenerative diseases, particularly Alzheimer’s and Parkinson’s.

Researchers find a way to wipe out the brain’s immune cell corps and send in new and improved versions.

From a Nobel prize and photosynthesis-powered brains to neurodegeneration research and controversy over a new Alzheimer’s drug, a look back at some of the biggest brain-related developments of the year.
