David Peterzell's Phantom Pulse Effect 2: Subject AB2

Peterzell, D. (2008). The phantom pulse effect: Rapid left-right mirror reversals evoke unusual sensations of phantoms, movements, and paresthesias in the limbs and faces of normals and amputees [Abstract]. Journal of Vision, 8(6):830, 830a, http://journalofvision.org/8/6/830/, doi:10.1167/8.6.830.

In this video, a young normal (non-amputee) subject (AB2) experiences the phantom pulse effect. As with approximately 2% of the population, she experiences the effect not just in her hand, arms and shoulder, but also her face.




I am now referring to these individuals as "Super Paresthetes, Type I. AB2 has a sister and two brothers who all have such responses, suggesting a possible genetic role in the effect. (The father experiences no phantom pulse; haven't tested the mother yet). Additional videos demonstrate the effect in AB2's siblings.

Audio is a little out of synch... not sure why.
