Goal-directed behavior requires the continuous monitoring and dynamic adjustment of ongoing actions. Here, we report a direct coupling between event-related electroencephalogram (EEG), functional magnetic resonance imaging (fMRI), behavioral measures performance in humans. By applying independent component analysis to EEG signals recorded simultaneously with fMRI, found single-trial error-related negativity be systematically related subsequent trial, thereby reflecting immediate adjustments...

A growing number of virtual reality devices now include eye tracking technology, which can facilitate oculomotor and cognitive research in VR enable use cases like foveated rendering. These applications require different performance, often measured as spatial accuracy precision. While manufacturers report data quality estimates for their devices, these typically represent ideal performance may not reflect real-world quality. Additionally, it is unclear how precision change across sessions...

Abstract Evidence in the literature for proposed relationship between error‐related negativity (ERN) and error correction is rather limited inconsistent. We investigated corrective behavior ERN two groups of participants who performed a flanker task. The correction‐instructed group was asked to immediately correct all encountered errors. noninstructed unaware that responses were recorded. found negative deflection following corrected errors peaked at 200–240 ms after error. refer this ERP...

Predictive mechanisms are essential to successfully interact with the environment and compensate for delays in transmission of neural signals. However, whether how we predict multisensory action outcomes remains largely unknown. Here investigated existence predictive a context where actions have different modalities. During fMRI data acquisition auditory, visual auditory-visual stimuli were presented active passive conditions. In condition, self-initiated button press elicited variable short...

Significance Tactile sensations on a moving hand are perceived weaker than when presented the same but stationary hand. There is an ongoing debate about whether this perception based sensorimotor predictions or due to blanket reduction in sensitivity. Here, we show greater suppression of matching predicted sensory feedback. This reinforces idea precise estimations future body states suppressing Our results shine light mechanisms human control and relevant for understanding clinical phenomena...

The primate dorsal pathway has been proposed to compute vision for action. Although recent findings suggest that structures contribute somatosensory action control as well, it is yet not clear whether or the development of functions depends on early visual experience. Using functional magnetic resonance imaging, we investigated pattern cortical activation in congenitally blind and matched blindfolded sighted adults while performing kinesthetically guided hand movements. Congenitally...

Grasping behaviors require the selection of grasp-relevant object dimensions, independent overall size. Previous neuroimaging studies found that intraparietal cortex processes size, but it is unknown whether graspable dimension (i.e., grasp axis between selected points on object) or size objects triggers activation in region. We used functional magnetic resonance imaging adaptation to investigate human brain areas involved processing real 3-dimensional grasping and viewing tasks. Trials...

Echolocation can be used by blind and sighted humans to navigate their environment. The current study investigated the neural activity underlying processing of path direction during walking. Brain was measured with fMRI in three echolocation experts, novices. During scanning, participants listened binaural recordings that had been made prior scanning while experts echolocated walking along a corridor which could continue left, right, or straight ahead. Participants also control sounds...

Abstract Sensorimotor control of human action integrates feedforward policies that predict future body states with online sensory feedback. These predictions lead to a suppression the associated feedback signals. Here, we examine whether somatosensory processing throughout goal-directed movement is constantly suppressed or dynamically tuned so enhanced at critical moments movement. Participants reached towards their other hand in absence visual input and detected probing tactile stimulus on...

Introduction To interact with the environment, it is crucial to distinguish between sensory information that externally generated and inputs are self-generated. The consequences of one’s own movements tend induce attenuated behavioral- neural responses compared inputs. We propose a computational model attenuation (SA) based on Bayesian Causal Inference, where SA occurs when an internal cause for inferred. Methods Experiment 1 investigates during stroking movement. Tactile stimuli finger were...

Abstract Vision is important for various tasks, from visually tracking moving objects to maintaining balance. People obtain visual information through eye movements performed either alone or in combination with head movements. Even when isolated can accommodate the amplitude of desired gaze shift, humans still perform movements, as they provide additional sensory signals that be integrated retinal input resulting improved estimates. However, also create mechanical torques and attenuate...

Abstract Successful behaviour requires error detection resulting in remedial actions, such as immediate correction. The present event‐related functional magnetic resonance imaging study humans examined the neural correlates of and correction using a speeded modified flankers task. In order to investigate corrective behaviour, participants were randomly divided into two groups. instructed group was asked correct all encountered errors immediately. not unaware that responses recorded....

Abstract The so-called mirror neuron system (MNS) responds when humans observe actions performed by a member of their own species. This activity is understood as an internal motor representation the observed movement pattern. By contrasting meaningless human hand movements with artificial objects in space, we tested claim that exclusively belonging to repertoire have direct access MNS. Eighteen participants video clips moving hands and while hemodynamic response was recorded functional...

When interacting with our environment we generally make use of egocentric and allocentric object information by coding positions relative to the observer or environment, respectively. Bayesian theories suggest that brain integrates both sources optimally for perception action. However, experimental evidence integration is sparse has only been studied using abstract stimuli lacking ecological relevance. Here, investigated during memory-guided reaching images naturalistic scenes. Participants...

The perception of tactile stimuli presented on a moving hand is systematically suppressed. Such suppression has been attributed to the limited capacity brain process task-irrelevant sensory information. Here, we examined whether humans do not only suppress movement-irrelevant but also enhance in parallel movement-relevant signals when performing goal-directed reaching movement. Participants reached either visual (LED) or somatosensory target (thumb index finger their unseen static hand) and...

There is wide agreement that the "dorsal (action) stream" processes visual information for movement control. However, movements depend not only on vision but also tactile and kinesthetic (=haptics). Using functional magnetic resonance imaging, present study investigates to what extent networks within dorsal stream are utilized action control whether they involved in working memory. Fourteen blindfolded participants performed a delayed-recognition task which right-handed had be encoded,...

Tactile stimuli on moving limbs are typically attenuated during reach planning and execution. This phenomenon has been related to internal forward models that predict the sensory consequences of a movement. suppression is considered occur due match between actual predicted movement, which might free capacities process novel or task-relevant signals. Here, we examined whether how tactile depends relevance somatosensory information for reaching. Participants reached with their left right index...

Somatosensory perception is hampered on the moving limb during a goal-directed movement. This somatosensory suppression mostly attributed to forward model that predicts future states of system based established motor command. Here, we examined whether and how this modulated by predictability object features important for controlling grasping Participants reached grasp an between thumb index finger then lifted it as straight possible. Objects with symmetric or asymmetric mass distributions...
