HH Krämer, C Stenner, S Seddigh, T Bauermann… - The Journal of …, 2008 - Elsevier
Allodynia means that innocuous tactile stimulation is felt as pain. Accordingly, cerebral
activations during allodynia or touch should markedly differ. The aim of this study was to
investigate whether the imagination of allodynia affects brain processing of touch in healthy
subjects. Seventeen healthy subjects divided into 2 subgroups were investigated: The first
group (n= 7) was familiar with allodynia, based on previous pain studies, whereas the
second group (n= 10) had never knowingly experienced allodynia. Using functional …
