Invariant neural subspaces maintained by feedback modulation
eLife, 2022 Sensory systems reliably process incoming stimuli in spite of changes in context. Most recent models accredit this context invariance to an extraction of increasingly complex sensory features in hierarchical feedforward networks.

B:Ionic Glove: A Soft Smart Wearable Sensory Feedback Device for Upper Limb Robotic Prostheses
IEEE Robotics and Automation Letters, 2021 Upper limb robotic prosthetic devices currently lack adequate sensory feedback, contributing to a high rejection rate. Incorporating affective sensory feedback into these devices reduces phantom limb pain and increases control and acceptance.

Sensory Augmentation Using Subdermal Haptic Feedback
Engineering Proceedings, 2022 The goal of this study is to introduce an implantable haptic feedback device that allows a user to obtain better interactions and feedback from various sensory modules. A thorough analysis of the design of the sensor is provided in this work.

Effect of Sensory Attenuation on Cortical Movement-Related Oscillations [PDF]
, 2018 This study examined the impact of induced sensory deficits on cortical, movement-related oscillations measured using electroencephalography (EEG). We hypothesized that EEG patterns in healthy subjects with induced sensory reduction would be comparable to

Integration of sensory force feedback is disturbed in CRPS-related dystonia. [PDF]
PLoS ONE, 2013 Complex regional pain syndrome (CRPS) is characterized by pain and disturbed blood flow, temperature regulation and motor control. Approximately 25% of cases develop fixed dystonia.

Simulating Cortical Feedback Modulation as Changes in Excitation and Inhibition in a Cortical Circuit Model. [PDF]
, 2016 Cortical feedback pathways are hypothesized to distribute context-dependent signals during flexible behavior. Recent experimental work has attempted to understand the mechanisms by which cortical feedback inputs modulate their target regions.

Journal of NeuroEngineering and Rehabilitation, 2020 Background Human sensorimotor control of dexterous manipulation relies on afferent sensory signals. Explicit tactile feedback is generally not available to prosthetic hand users, who have to rely on incidental information sources to partly close the ...

Movement predictability modulates sensorimotor processing
Frontiers in Human Neuroscience, 2023 IntroductionAn important factor for optimal sensorimotor control is how well we are able to predict sensory feedback from internal and external sources during movement. If predictability decreases due to external disturbances, the brain is able to adjust

A robot hand testbed designed for enhancing embodiment and functional neurorehabilitation of body schema in subjects with upper limb impairment or loss. [PDF]
, 2015 Many upper limb amputees experience an incessant, post-amputation "phantom limb pain" and report that their missing limbs feel paralyzed in an uncomfortable posture.
