Predictive somatosensory signals during goal-directed movementsA4
Project A4 investigates how predictions about the sensory consequences of our own actions shape tactile perception. First, we want to examine how flexibly tactile perception can be modulated by predicted movement demands in reaching and grasping. Second, we aim to test the hypothesis that movement-induced tactile suppression facilitates processing of more relevant sensory signals. Third, we want to identify the cortical network associated with tactile suppression and examine how activation in this network is influenced by the relevancy of movement-related sensory signals and by central motor commands. Fourth, we aim to answer the question whether tactile suppression is caused by a general suppression or by a specific prediction leading to an explicit discount of the sensory consequences of our own actions.
Project A4 aims to investigate the mutual interaction of perception and action associated with the concepts of inverse and forward models. First, we want to examine the contribution of different somatosensory stimulus qualities to movement planning by studying saccadic eye and reaching movements to tactile, proprioceptive and kinesthetic targets. Second, we want to determine at the behavioral and brain level how movement planning and execution alter somatosensory perception based on predictive mechanisms by measuring movement-induced sensory suppression while varying the availability of afferent and efferent feedback signals and the expectation of future sensory and motor events.
