Human sensorimotor cortex represents conflicting visuomotor mappings.
Behavioral studies have shown that humans can adapt to conflicting sensorimotor mappings that cause interference after intensive training. While previous research works indicate the involvement of distinct brain regions for different types of motor learning (e.g., kinematics vs dynamics), the neural mechanisms underlying joint adaptation to conflicting mappings within the same type of perturbat...
متن کاملSwitching between visuomotor mappings: learning absolute mappings or relative shifts.
Adaptation to specific visuomotor mappings becomes faster when switching back and forth between them. What is learned when repeatedly switching between the visuomotor mappings: the absolute mappings or the relative shift between the mappings? To test this, we trained participants in a rapid pointing task using a unique color cue as context for each mapping between pointing location and visual f...
متن کاملSynchronised oscillations of the human sensorimotor cortex.
Oscillations are a prominent feature of macroscopic human sensorimotor cortical activity as recorded non-invasively with electroencephalography (EEG) and magnetoencephalography (MEG). The advent of whole-scalp MEG systems allowing rapid non-invasive recording from the entire cortex and accurate localisation of neural sources, and the development of refined signal analysis methods are important ...
متن کاملInferring Visuomotor Priors for Sensorimotor Learning
Sensorimotor learning has been shown to depend on both prior expectations and sensory evidence in a way that is consistent with Bayesian integration. Thus, prior beliefs play a key role during the learning process, especially when only ambiguous sensory information is available. Here we develop a novel technique to estimate the covariance structure of the prior over visuomotor transformations--...
متن کاملHuman Orbitofrontal Cortex Represents a Cognitive Map of State Space
Although the orbitofrontal cortex (OFC) has been studied intensely for decades, its precise functions have remained elusive. We recently hypothesized that the OFC contains a "cognitive map" of task space in which the current state of the task is represented, and this representation is especially critical for behavior when states are unobservable from sensory input. To test this idea, we apply p...
