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 (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. [1]

Sensory neuron cell bodies are located in:
Each has a single axon that divides into peripheral (receptor) and central (spinal cord/brainstem) branches.
Voltage-gated sodium channels in nociceptors.
Heat receptor; capsaicin receptor.
Cold receptor and irritant sensor.
Mechanical receptor for touch and proprioception.
Neuropeptide in peptidergic nociceptors.
The study of Sensory Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
