4 mai 2022 · White matter disease is an umbrella term for damage to your brain’s white matter caused by reduced blood flow to the tissue. It can cause issues with memory, balance and mobility. People who have risk factors for cardiovascular disease also have a greater risk of developing white matter disease.
8 aug. 2019 · Human brain white matter is a substantial expanse of cerebral tissue that acts as a support structure for the transfer of critical signals between the cortex, subcortex, and more distal central nervous system neuroanatomic structures.
7 mar. 2024 · The brain's white matter (WM) constitutes a network of nerve fibers that allows the exchange of information and communication between different areas of the gray matter (GM). WM lies beneath the GM in the brain and superficial to GM in the spinal cord and has evolved more than GM and occupies almost half of the brain. [1] .
MR scan of the brain typically shows patchy T2-weighted/fluid attenuated inversion recovery (FLAIR) signal changes in the periventricular and deep white matter, which become confluent over time with involvement of the pons, thalamus and basal ganglia.
21 mai 2009 · The subcortical white matter makes up around half of the human brain volume. It is responsible for the interconnection of cortical and subcortical areas, participating in the constitution of the wide neural networks related to a host of motor, sensory, cognitive, and behavioral functions.
17 aug. 2022 · A thorough understanding of subcortical white matter anatomy is critical for the neurosurgeon. The subcortical white matter fasciculi are anatomo-functionally categorized into projection, association, limbic, commissural, or U-fiber systems.
1 nov. 2016 · White matter provides the structural connectivity between gray matter regions throughout the brain, and the importance of myelinated systems in cognitive function derives support from both behavioral neurology and basic neuroscience.
