"Unlocking the Secrets of Nerve Growth: How Skin Directs Sensation"
Researchers at Harvard Medical School have discovered that the skin, rather than pre-existing genetic programming, instructs nerve cells on how to mature for specific sensory tasks. The study found that skin cues determine whether nerve endings develop to detect sensations in hairy or hairless skin. This finding could potentially lead to therapies for damaged nerves and a better understanding of congenital neuropathies. The research highlights the significant role of the skin in neural development.
