TED-Ed・2 minutes read
Ian Waterman lost his ability to move or feel anything below the neck due to a rare nervous system condition, emphasizing the importance of somatosensory system functions in daily life and social interactions. Damage to this system can lead to a loss of tactile and proprioceptive sensations, impacting bodily functions and relationships.
Insights
- Ian Waterman's rare deafferentation condition, where he lost movement and sensation due to disrupted nervous signals, showcases the vital role of the somatosensory system in processing touch, pain, and proprioception.
- The impairment of the somatosensory system, as seen in Waterman's case, not only affects physical sensations but also has profound implications on daily functions and social interactions, emphasizing the significance of these sensory experiences in our perception of the world.

Ian Waterman: Lost Sensations, Life Altered
- In 1971, Ian Waterman developed a rare form of deafferentation after a bout of gastric flu, leaving him unable to move or feel anything from the neck down due to interrupted nervous system signals.
- The somatosensory system, responsible for touch, pain, temperature, and proprioception, relies on millions of receptor cells in the skin, muscles, and organs to process sensations and relay information to the brain through varying fiber thicknesses.
- Damage to the somatosensory system, like in Waterman's case, can lead to a loss of tactile and proprioceptive sensations, impacting bodily functions and social interactions, highlighting the crucial role these invisible sensations play in navigating the world.
