Research Interests

  • Movement control with sensory substitution devices: sensory substitution devices (SSDs) convey information usually conveyed by one sense (e.g., vision) using another sense (e.g., audition). With Prof. Amir Amedi, I have been studying movements made to targets presented by auditory signals. We compare these to movements made towards visual targets. We found that participants made fast and accurate movements using the SSD, similar to movements made when visual feedback was available. The ultimate goal is to design aids for the Blind and the visually impaired, to assist in their perception and interaction with their environment. Our recently published paper compares movements with an SSD to visually guided movements. In this study, we used the EyeMusic, a visual-to-auditory SSD, which conveys visual information using musical notes.
  • In another recently published study, we showed that information about space that is learned with the visual sense is used when making movements that are guided by the EyeMusicSSD.
  • Rhythmic movement in healthy individuals: I have been studying rhythmic movements generated by healthy adults, and together with my colleagues found evidence for at least two distinct sub-types of rhythmic movement: one that is of a more discrete nature, and one that is of a more harmonic nature. With Prof. Amir Karniel, I studied the potential sources for the choice made by the human motor control system to employ one movement type vs. the other.
  • Rhythmic movement in Parkinson's disease patients: In studying rhythmic movements generated by individuals with Parkinson's disease, we have described a fascinatingmitigatory effect that removing visual feedback has on bradykinesia (slowness of movement; a hallmark of the disease). This finding opens the door to potential new approaches to physical therapy for PD patients, as a complement to existing ones.
  • Handshake movements in healthy individuals and individuals with Cerebral Palsy (CP): As part of the "Handhshake team" at the CMCL, and in collaboration with Dr. Simona Bar-Haim, we studied the rhythmic nature of the human handshake, and the variations in movement parameters with CP.
