Aug 13, 2024 · A new study zeroes in on how 40Hz sensory stimulation helps to sustain an essential process in which the signal-sending branches of neurons, called axons, are wrapped in a fatty insulation called myelin. Often called the brain’s “white matter,” myelin protects axons and insures better electrical signal transmission in brain circuits.
Jul 26, 2010 · White matter hyperintensities were significantly associated with an increased risk of death both in the general population and in high risk populations with a history of stroke, depression, or minor neurological symptoms. This association could be mediated by an increased risk of stroke and dementia.

May 5, 2022 · The increased volume of white matter – mainly from the myelin sheaths that surround axons – enhances the efficiency of neurons in the gray matter to optimize brain function.

Feb 4, 2022 · Here, we parcellated WMH using a novel system that segments WMH based on both lobar regions and distance from the ventricles, dividing the brain into a coordinate system composed of 36 distinct...
As a neurologist, I am often asked to see patients because they have a magnetic resonance image (MRI) of the brain showing white matter hyperintensities (WMHs). These patients, and the clinicians who refer them to me, want to know the answers to several questions: What are WMHs and what causes them?
