Long-range axons in mammalian brains travel through white matter tracts to optimize signal transmission.
the verdict
SUPPORTED
the evidence backs this
confidence 78/100
Evidence from neuroanatomy and tractography confirms that long-range axons in mammalian brains travel through myelinated white matter tracts characterized by optimal diameters and high myelination to facilitate efficient and rapid signal transmission between distant regions.
