Spatial localisation of touch on a robotic limb in the absence of direct haptic feedback

This study shows that indirect tactile signals from a robotic thumb can be discriminated and used to spatially localise touch, even without direct haptic feedback.

The spatial coding of touch is defined in intrinsic, limb-specific coordinates: an EEG study

This study uses EEG to show that touch is encoded in an intrinsic, limb-specific spatial code rather than an extrinsic, limb-independent one.

Dynamics of sensorimotor plasticity during spatial finger augmentation

This study investigates how the brain integrates a wearable finger-extension device into somatosensory representations across different interaction phases, finding three distinct phases of plasticity.

Bayesian inference in arm posture perception

The paper tests a Bayesian model of arm posture perception using a VR task, finding that a Gaussian prior better explains individual biases than a uniform prior.

Tool use fine-tunes arm and tool maps

The paper investigates whether hand-held tools can be mapped in space with the same precision as body parts and whether tool use alters these spatial maps.

Biases in hand perception are driven by somatosensory computations, not a distorted hand model

The paper shows that biases in hand perception arise from Bayesian integration of somatosensory signals, not from a distorted internal hand model.
