Understanding brain activity during sleep to detect early neurological changes

"Complex processes are going on in the brain when we sleep," says Dr Karolina Armonaitė, a neuroscientist from Kaunas University of Technology, Lithuania. According to her, a more precise understanding of what happens in different areas of the cerebral cortex during sleep can help diagnose sleep disorders and neurological diseases more accurately.

Study reveals dopamine sends precise signals rather than broad brainwide messages

A new study from the University of Colorado Anschutz Medical Campus has upended decades of neuroscience dogma, revealing that dopamine, a neurotransmitter critical for movement, motivation, learning and mood, communicates in the brain with extraordinary precision, not broad diffusion as previously believed.

New insights into neural replay and memory formation from flying bats

Every day, our brain takes countless fleeting experiences - from walks on the beach to presentations at work - and transforms them into long-term memories.

Side of onset influences non-motor symptoms in Parkinson’s disease

Parkinson's disease often begins asymmetrically, affecting either the right or left side of the body first. Researchers from the University of Geneva (UNIGE) and the Geneva University Hospitals (HUG) have demonstrated that this initial side of onset influences the progression of non-motor symptoms.

Theater activities enhance emotional well-being in Parkinson’s patients

A research team at the Universitat Oberta de Catalunya (UOC), working with the Hospital Sant Pau in Barcelona, has shown that theatre can improve the emotional well-being of people with Parkinson's disease.

Targeting a key enzyme could reverse early Parkinson's effects

Putting the brakes on an enzyme might rescue neurons that are dying due to a type of Parkinson's disease that's caused by a single genetic mutation, according to a new Stanford Medicine-led study conducted in mice.

Brain cells can burn fat to fuel activity

While glucose, or sugar, is a well-known fuel for the brain, Weill Cornell Medicine researchers have demonstrated that electrical activity in synapses—the junctions between neurons where communication occurs—can lead to the use of lipid or fat droplets as an energy source.

Clinical trial examines whether Ambroxol can slow dementia in people with Parkinson's

Dementia poses a major health challenge with no safe, affordable treatments to slow its progression.

New 3D model reveals how nose stem cells support sense of smell

Using a newly devised, three-dimensional model to study the regeneration of nerve tissue in the nose, researchers at Tufts University School of Medicine and the Graduate School of Biomedical Sciences (GSBS) and colleagues have discovered that one type of stem cell thought to be dormant may play a more significant role in preserving the sense of smell than originally believed.

New screening method for Parkinson's analyzes odors in ear wax

Most treatments for Parkinson's disease (PD) only slow disease progression. Early intervention for the neurological disease that worsens over time is therefore critical to optimize care, but that requires early diagnosis.
