Feeling Touched: Emotional Modulation of Somatosensory Potentials to Interpersonal Touch

N. Ravaja, V. Harjunen, I. Ahmed, G. Jacucci, M. M. Spapé
2017 Scientific Reports  
Touch processing was indexed using SEPs, and self-reports of touch experience were collected.  ...  The affective modulation of touch was initially obtained as early as 25 ms after the touch onset suggesting that emotional context is integrated to the tactile sensation at a very early stage.  ...  For behavioural data, four ANOVAs were conducted with pleasantness and intensity of touch and expression as dependent variables.  ...

Emotion Perception from Face, Voice, and Touch: Comparisons and Convergence

Annett Schirmer, Ralph Adolphs
2017 Trends in Cognitive Sciences  
Regions typically more active for emotional as compared to neutral stimuli are marked in green, blue, and red for voice, face, and touch, respectively.  ...  We review stimulus characteristics and ensuing behavioral and brain responses, and show that audition and touch do not simply duplicate visual mechanisms.  ...  Such patients are impaired at localizing touch on their body, but can still perceive it as pleasant, and selectively activate the insula [59] .  ...
