Late-onset Cerebellar Ataxia Genetic Cause Identified

Researchers have identified a previously unknown genetic cause of late-onset cerebellar ataxia. The finding will help with diagnosis and open up new treatment options for this progressive disease. Late-onset cerebellar ataxias (LOCA) are a diverse group of neurodegenerative diseases that cause unsteadiness in adults. Cerebellar ataxia is a type of ataxia that begins in the…

Ergothioneine In Blood May Predict Dementia Risk

An increased risk of cognitive decline and dementia in older adults may be predicted by low levels of ergothioneine in blood plasma, suggests a recent study. The results point to potential therapeutic or early detection methods for dementia and cognitive impairment in the elderly. More than a century ago, the French pharmacist Charles Joseph Tanret…

Transcranial Photobiomodulation Enhances Short Term Memory

A new study found that transcranial photobiomodulation, a type of laser light therapy, improved short-term memory. Scientists from the University of Birmingham in the United Kingdom and Beijing Normal University in China demonstrated that the non-invasive therapy could improve people’s short-term or working memory by up to 25%. The right prefrontal cortex of the brain…

Medulla Oblongata Function and Location

The medulla oblongata or simply medulla is a long stem-shaped brain structure which comprises the lower section of the brainstem. It is in front of and partly under the cerebellum. The cardiac, respiratory, vomiting and vasomotor nerve centers are contained in the medulla. Consequently, it handles the autonomic functions of breathing, heart rate and blood…

Having Bad Dreams Could Be Early Parkinson’s Disease Sign

In a group of older men, individuals having frequent bad dreams were twice as likely to be later diagnosed with Parkinson’s disease as those who did not, new research from University of Birmingham reports. Although it can be really beneficial to diagnose Parkinson’s disease early, there are very few risk indicators and many of these…

Anti-inflammatory Exercise Factors That Are Transferrable Benefit the Brain

Blood taken from young adult mice that get lots of exercise benefits the brains of same-aged, sedentary mice, new research1 shows. A single protein called clusterin in the blood of exercising mice seems mainly responsible for the effect. The finding could open the door to treatments that lower risk of neurodegenerative disease or slow its…

What Are Ranvier Nodes

Nodes of Ranvier are myelin sheath gaps. They appear along a myelinated axon where the axolemma is exposed to the extracellular space. Nodes of Ranvier are uninsulated and highly enriched in ion channels, allowing them to participate in the exchange of ions required to regenerate the action potential. Nerve conduction in myelinated axons is referred…

Music’s Potential As A Treatment For Parkinson’s, Stroke, And Brain Injury

You probably don’t realise it when you’re listening to your favourite song, but music has an incredibly powerful effect on the human brain. Singing, playing an instrument or listening to music have all been shown to activate numerous areas of the brain that control speech, movement and cognition, memory and emotion – often all at…
