Tactile stimulation

Tactile stimulation improves in-between test accuracy in humans.

“Higher finger numerosity estimation and accuracy were observed when tactile stimulations were delivered on the glabrous skin compared to the hairy skin”

Ageing reduces access to the body structural representations both for the glabrous and hairy skin surfaces
