Neural signatures of motor imagery for a supernumerary thumb in VR: an EEG analysis
Autor: Haneen Alsuradi, Joseph Hong, Alireza Sarmadi, Robert Volcic, Hanan Salam, S. Farokh Atashzar, Farshad Khorrami, Mohamad Eid
Publikováno v: Scientific Reports, Vol 14, Iss 1, Pp 1-15 (2024)
Abstract Human movement augmentation is a rising field of research. A promising control strategy for augmented effectors involves utilizing electroencephalography through motor imagery (MI) functions. However, performing MI of a supernumerary effecto

The endless visuomotor calibration of reach-to-grasp actions
Autor: Robert Volcic, Fulvio Domini
Publikováno v: Scientific Reports, Vol 8, Iss 1, Pp 1-11 (2018)
Abstract It is reasonable to assume that when we grasp an object we carry out the movement based only on the currently available sensory information. Unfortunately, our senses are often prone to err. Here, we show that the visuomotor system exploits

Saccadic adaptation to moving targets.
Autor: Katharina Havermann, Robert Volcic, Markus Lappe
Publikováno v: PLoS ONE, Vol 7, Iss 6, p e39708 (2012)
Saccades are so called ballistic movements which are executed without online visual feedback. After each saccade the saccadic motor plan is modified in response to post-saccadic feedback with the mechanism of saccadic adaptation. The post-saccadic fe

Tool-sensed object information effectively supports vision for multisensory grasping
Autor: Ivan Camponogara, Alessandro Farnè, Robert Volcic
Tools enable humans to extend their sensing abilities beyond the natural limits of their hands, allowing them to sense objects as if they were using their hands directly. The similarities between tool-mediated and hand-based sensing entail the existe

Not only perception but also grasping actions can obey Weber’s law
Autor: Zoltan Derzsi, Robert Volcic
Weber’s law, the principle that the uncertainty of perceptual estimates increases proportionally with object size, is regularly violated when considering the uncertainty of the grip aperture during grasping movements. The origins of this perception

Visual Uncertainty Unveils the Distinct Role of Haptic Cues in Multisensory Grasping
Autor: Robert Volcic, Ivan Camponogara
Publikováno v: eneuro. 9:ENEURO.0079-22.2022
Human multisensory grasping movements (i.e., seeing and feeling a handheld object while grasping it with the contralateral hand) are superior to movements guided by each separate modality. This multisensory advantage might be driven by the integratio

A brief glimpse at a haptic target is sufficient for multisensory integration in reaching movements
Autor: Robert Volcic, Ivan Camponogara
Publikováno v: Vision research. 185
Goal-directed aiming movements toward visuo-haptic targets (i.e., seen and handheld targets) are generally more precise than those toward visual only or haptic only targets. This multisensory advantage stems from a continuous inflow of haptic and vis

Integration of haptics and vision in human multisensory grasping
Autor: Robert Volcic, Ivan Camponogara
Publikováno v: Cortex; a journal devoted to the study of the nervous system and behavior. 135
Grasping actions are directed not only toward objects we see but also toward objects we both see and touch (multisensory grasping). In this latter case, the integration of visual and haptic inputs improves movement performance compared to each sense

Our interaction with objects is facilitated by the availability of visual feedback. Here, we investigate how and when visual feedback affects the way we grasp an object. Based on the main views on grasping (reach-and-grasp and double-pointing views),
