This was about five years ago. I look forward to seeing a similar exercise with the full-on “UPE imaging.”
In the meantime here’s something that anyone can try, no laboratory needed:
Voluntarily Generated Piloerection (VGP)—the ability to consciously trigger goosebumps—is still considered a medical and physiological mystery. Here's why it continues to puzzle researchers:
🧠 Why It “Shouldn’t Be Possible”
- Goosebumps are triggered by the arrector pili muscles, which are smooth muscles controlled by the autonomic nervous system—the part of your body that handles involuntary functions like heartbeat and digestion
- Since these muscles lack direct motor control pathways, conscious activation defies current neurophysiological models
🔍 What We Know So Far
- A 2018 study led by James Heathers examined 32 individuals with VGP and found remarkable consistency in how they described the sensation: it often starts at the back of the head or neck and spreads down the spine and arms
- Most participants said it was as easy as moving an arm, requiring no emotional trigger—just a simple mental or muscular focus
- Interestingly, many of these individuals scored high on openness to experience, suggesting a possible psychological link
🧬 Still Unexplained
- Despite anecdotal reports and small studies, no definitive mechanism has been identified to explain how VGP works
