Three-dimensional neuroanatomy of the intra-epidermal nervous system.
Authors
Abstract
Intra-epidermal nerve fibers (IENFs) are presumed to comprise mainly of itch-transmitting nerve fibers, and variations in their density have been studied in itch disorders; epidermal nerve fiber density is also a criterion in diagnosing small fiber neuropathy in clinical neurological practice. IENFs are typically identified with 2-dimensional (2D) histological slides, but 2D sections do not accurately represent nerves, which branch out in three-dimensions (3D).
