Interplay between MRI-based axon diameter and myelination estimates in macaque and human brain
Ting Gong, Chiara Maffei, Evan Dann +6
Axon diameter and myelin thickness affect the conduction velocity of action potentials in the nervous system. Imaging them non-invasively with MRI-based methods is thus valuable fo…
