Listen "JNP Micro Podcasts ”Four Questions”: Johannes Keyser, and Leonie Oostwoud Wijdenes"
Episode Synopsis
In this podcast Johannes Keyser (Justus Liebig University Giessen) and Leonie Oostwoud Wijdenes (Radboud University Nijmegen) talk about their recently published research "Late integration of vision and proprioception during perturbed reaches."
NEW & NOTEWORTHY Both visual and proprioceptive signals provide information about arm state during reaching. By perturbing the perceived, but not the actual, position of the hand in both modalities using visual disturbances and muscle vibration, we examined multimodal integration and state estimation during reaching. Our results suggest that the early reach corrections are based on separate state estimates from the two sensory modalities and only later are based on a combined state estimate.
