Researchers investigate functional advantages of traveling brain waves during working memory

Researchers investigate functional advantages of traveling brain waves during working memory

After more than a century of study, the significance of brain waves – the coordinated, rhythmic electrical activity of groups of brain cells – is still not fully known. An especially underappreciated aspect of the phenomenon is that waves spatially propagate, or "travel," through brain regions over time.

Oligodendrocytes may have a different role in the development of multiple sclerosis, study finds

Oligodendrocytes may have a different role in the development of multiple sclerosis, study finds

An international team of researchers led by Karolinska Institutet in Sweden have discovered that a cell type in the central nervous system known as oligodendrocytes might have a different role in the development of multiple sclerosis (MS) than previously thought.

Blood tests may enable simpler, more accurate early diagnosis of ALS

Blood tests may enable simpler, more accurate early diagnosis of ALS

Blood tests may enable more accurate diagnosis of ALS at an earlier stage of the disease. As described in a study by researchers at University of Gothenburg and Umeå University, it involves measuring the blood level of a substance that, as they have also shown, varies in concentration depending on which variant of ALS the patient has.

Novel experimental drug designed to silence FUS gene may help treat ALS

Novel experimental drug designed to silence FUS gene may help treat ALS

Using an experimental drug, researchers were able to suppress a mutated amyotrophic lateral sclerosis (ALS) gene.

REM sleep protects animals against predator attacks

REM sleep protects animals against predator attacks

Rapid eye movement (REM) sleep brings about brief but periodic awakenings. In 1966, Dr. Frederick Snyder reported the "sentinel" function of REM could help animals prepare a fight or flight response against potential predator attacks.

Single type of neuron found to be responsible for keeping our legs in lockstep

Single type of neuron found to be responsible for keeping our legs in lockstep

Walking is the most natural of movements. Without thinking, we put one foot forward and then the next, on and on, propelling us forward. So, if we're not consciously directing this complex interplay of nerves and muscles, what is?

Mice study identifies ventral spinocerebellar tract neurons that control locomotion

Mice study identifies ventral spinocerebellar tract neurons that control locomotion

For more than a century, scientists have known that while the commands that initiate movement come from the brain, the neurons that control locomotion once movement is underway reside within the spinal cord.

Scientists reveal toxic astrocyte changes in ALS

Scientists reveal toxic astrocyte changes in ALS

Scientists at the Francis Crick Institute have revealed harmful changes in supporting cells, called astrocytes, in Amyotrophic Lateral Sclerosis (ALS) in two publications in Brain and Genome Research.

Machine learning model identifies new risk genes for motor neurone disease

Machine learning model identifies new risk genes for motor neurone disease

Scientists have developed a new machine learning model for the discovery of genetic risk factors for diseases such as Motor Neurone Disease (MND).

New and improved method for imaging the structure of neural connections

New and improved method for imaging the structure of neural connections

The glory of tissue expansion technologies is that when structures, such as proteins that build nerve cell connections, are too small for a microscope to resolve, clever chemistry can make everything bigger and easier to see.

UC researchers to examine how stress hormones affect cell degeneration in Parkinson's patients

Stress can have a negative effect on anyone's health but presents particular challenges for people with Parkinson's disease.

Novel biomarker can be used to identify disease progression in ALS

Novel biomarker can be used to identify disease progression in ALS

An international collaboration led by Flinders University has identified a potential biomarker for amyotrophic lateral sclerosis, also known as Motor Neuron Disease, providing a way to test the effectiveness of future clinical trials.

Study finds evidence for increased activity of the brain’s immune system long before dementia onset

Study finds evidence for increased activity of the brain’s immune system long before dementia onset

Long before the onset of dementia, there is evidence for increased activity of the brain's immune system. Researchers from DZNE and the University Hospital Bonn come to this conclusion based on a study of more than 1,000 older adults.

Small cluster of neurons in the brain stem found to coordinate vocalization with breathing

Small cluster of neurons in the brain stem found to coordinate vocalization with breathing

The vocal sounds of humans - laughing, crying, and the babbling of babies - have the same rhythmic quality as the sounds made by many mammals, songbirds, and even some species of fish.

Research uncovers how a mouse brain understands sensory information

Research uncovers how a mouse brain understands sensory information

The brain is the most complex organ in our body – constantly absorbing and interpreting our surroundings, and guiding our movement, thoughts, behaviors and emotions.
