workshop 1 - white matter

what is white matter composed of

myelinated neurons

role of white matter

to provide connections between different cortical regions

importance of connections

are essential for cognitive function

white matter damage

• results in the breakdown of connectivity

• leads to cognitive deficits - disconnection syndrome

white matter and brain development

changes and strengthens connections between different cortical regions which are essential to brain development and maturation

• some neurodevelopmental disorders are a result of abnormal connectivity

white matter and brain plasticity

changes as we learn or practise new skills (brain plasticity)

study of white matter

Brain imaging techniques, DTI (diffusion tensor imaging) and tractography are used to non-invasively study white matter and connectivity in the human brain
