If that involuntary action seems to yield a welcomed head-clearing effect, new science suggests that just might be true.

The human brain has no conventional lymph nodes, no obvious drainage pipes. For most of medical history, scientists assumed it simply recycled its own waste internally. That picture has been crumbling ...

Structural imaging based on magnetic resonance is an integral part of the clinical assessment of patients with suspected Alzheimer dementia. Prospective data on the natural history of change in ...

Monocytes are central to innate and adaptive immunity, regulating tissue homeostasis and inflammation. However, data on their ...

The brain and spinal cord are surrounded by a clear fluid called cerebrospinal fluid (CSF). The CSF supports and protects the brain and the spinal cord. Some brain tumours block the normal circulation ...

Objective Marchiafava–Bignami disease (MBD) is a rare condition mainly associated with alcoholism, although it may be mimicked by several other disorders that cause corpus callosum lesions. Our ...

Whole-body MRI (WB-MRI) may improve ALS diagnostic certainty. WB-MRI assesses muscle swelling (edema) as a marker for lower ...

A group of researchers from the Technion and the United States reports a breakthrough in MRI scanning in a paper published in ...

Biomedical engineers at Duke University have developed a technique to noninvasively visualize the brain's waste-removal system in unprecedented detail. This new imaging approach allows researchers to ...

The high sensitivity of MRI in the depiction of plaques in the brain and spinal cord has made this technique the most important paraclinical tool for the diagnosis of multiple sclerosis (MS). MRI ...

What are pineal region tumours? Pineal region brain tumours develop in the pineal gland or the surrounding tissue. The pineal gland is in the middle of the brain, just behind the brain stem. It makes ...
