Sensory Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Sensory [neurons](/entities/neurons) (afferent neurons) transmit sensory information from peripheral receptors to the central nervous system. They are essential for somatosensation including touch, pain, temperature, and proprioception. Dysfunction contributes to sensory neuropathies in neurodegenerative diseases. [@dubin2012]
