Scientists eager to explain brain rhythm boost’s broad impact in Alzheimer’s models

The sweeping extent to which increasing 40Hz “gamma” rhythm power in the brain can affect the pathology and symptoms of Alzheimer’s disease in mouse models has been surprising, even to the MIT neuroscientists who’ve pioneered the idea. So surprising, in fact, they can’t yet explain why it happens. In three papers, including two this year in Cell and Neuron, they’ve […]

Dementia study reveals how proteins interact to stop brain signals

Fresh insights into damaging proteins that build up in the brains of people with Alzheimer’s disease could aid the quest for treatments. A study in mice reveals how the two proteins work together to disrupt communication between brain cells. Scientists observed how proteins—called amyloid beta and tau—team up to hamper key genes responsible for brain messaging. By changing how genes […]

Deep neural networks uncover what the brain likes to see

Opening the eyes immediately provides a visual perception of the world—and it seems so easy. But the process that starts with photons hitting the retina and ends with ‘seeing’ is far from simple. The brain’s fundamental task in ‘seeing’ is to reconstruct relevant information about the world from the light that hits the eyes. Because this process is rather complex, […]

Mum who thought she just had 'baby brain' actually had a brain tumour

A new mum who put her headaches and tiredness down to ‘baby brain’ was devastated to discover she actually had an incurable brain tumour. Claire Curtis, 30, had been experiencing headaches and feeling tired for months before her diagnosis, but just put it down to the stress of being a new mum. Doctors prescribed her medication for migraines, but when […]

Alzheimer’s amyloid build-up affects certain parts of brain cells more than others in mice

A protein that is linked with Alzheimer’s Disease has been found to be more likely to affect certain parts of brain cells that send messages than other parts of the cells. In a new study published in Scientific Reports, the team observed how amyloid beta (Aβ), a protein which accumulates in the brain of people with Alzheimer’s disease, affected the […]

Gut instincts: Researchers discover first clues on how gut health influences brain health

New cellular and molecular processes underlying communication between gut microbes and brain cells have been described for the first time by scientists at Weill Cornell Medicine and Cornell’s Ithaca campus. Over the last two decades, scientists have observed a clear link between autoimmune disorders and a variety of psychiatric conditions. For example, people with autoimmune disorders such as inflammatory bowel […]

The night gardeners: Immune cells rewire, repair brain while we sleep

Science tells us that a lot of good things happen in our brains while we sleep—learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immune cells called microglia—which play an important role in reorganizing the connections between nerve cells, fighting infections, and repairing damage—are also primarily active while […]

Brain injury from concussion may linger longer than one year after return to play

How long does it take an athlete to recover from a concussion? New research has found an athlete’s brain may still not be fully recovered one year after being allowed to return to play. The study is published in the October 16, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology. “There is growing evidence […]
