WebVideo transcript. In this video, I want to talk about the effects of axon diameter and myelination because it turns out that larger diameter axons conduct action potentials faster than smaller diameter axons. And axons with a myelin sheath on them also conduct action potentials faster. WebOligodendrocytes are specialised glial cells that myelinate CNS axons. Myelinated axons are bundled together into white matter tracts that interconnect grey matter areas of the brain and are essential for rapid, integrated neuronal communication and cognitive function. Life-long generation of oligodendrocytes is required for myelination of new neuronal connections …

Anxiety and PTSD Linked to Increased Myelin in Brain’s Gray Matter

WebThe adhesion G protein-coupled receptor (GPCR) Gpr126 is essential for Schwann cells to initiate myelination, but previous studies have not addressed the role of Gpr126 signaling in myelin maturation and maintenance. Through analysis of Gpr126 in zebrafish, we define two distinct mechanisms controlling the initiation and maturation of myelin. お米について子供向け
