Web17 okt. 2024 · The functional role of differentiated myelination is to regulate and synchronise signal transmission across different axonal fibres to enable cognitive function, sensory integration and motor skills [ 5 ]. White-matter architecture has also been found to affect the peak frequency of the alpha rhythm [ 6 ]. Web5 okt. 2024 · Myelination of axonal pathways has long been recognized as necessary for enhancing action potential conduction within the central nervous system and thus essential for healthy brain function. However, plastic changes in myelin during adulthood have only recently started being widely reported.
