Assistant Professor of Biomedical Engineering @CWRU. Neural engineer. Sensory neuroscientist.
Joined April 2019
A four-year study will investigate how restoring touch with the innovative "iSens" neuroprosthetic system from CWRU can profoundly improve the lives of people with upper limb amputations. Assistant Professor @emily_graczyk is leading the research.

Thank you to our wonderful participant, our amazing neurosurgeons, and the whole ReHAB team, especially Brianna Hutchison and Rohit Bose (@rohitbose94) for leading this study! More details at: https://t.co/S8l6dT04kk 🧵5/5

Both intracortical microstimulation (ICMS) and peripheral nerve stimulation (PNS) can restore tactile sensation to people living with physical disabilities, such as spinal cord injury (SCI) or...

Lastly, using structural equation modeling, we found that perceived naturalness was more strongly related to other perceptual variables than to stimulation variables, suggesting that naturalness is a higher order perceptual dimension. 🧵4/5

PNS evoked higher intensity and more reliable percepts than ICMS, making it the better modality to deliver consistent and effective sensory feedback during closed-loop functional tasks. 🧵3/5

ICMS evoked more localized percepts and felt qualitatively more similar to natural touch compared to PNS, making it the better sensory stimulation approach for conveying naturalistic touch experiences. 🧵2/5

New preprint alert! 🚨 https://t.co/S8l6dSZwuM What is the perceptual difference between sensation from cortical stimulation (ICMS) and peripheral nerve stimulation (PNS)? We explored this fundamental question in a participant with sensory incomplete spinal cord injury. 🧵1/5

For artificial touch via peripheral nerve interfaces, sensation quality depends on the frequency of stimulation up to 60Hz. Above 60Hz, quality is constant. Out today in @JNeurosci with @emily_graczyk Breanne Christie @qinpuhehehe @FNILab

Electrical stimulation of the peripheral nerves of human participants provides a unique opportunity to study the neural determinants of perceptual quality using a causal manipulation. A major...

New article out today in @JNeurosci with @slimanjbensmaia @qinpuhehehe and Breanne Christie. Stimulation frequency modulates the quality of artificial touch up to ~60 Hz. Also developed a new method to normalize quality reports across subjects https://t.co/aU3OdxBTOx

Ended 2021 with a publication on a novel outcome measure for assessing the psychosocial experience of upper limb prosthesis users, developed with Linda Resnik at the Providence VAMC
journals.plos.org
Recent advances in upper limb prosthetics include sensory restoration techniques and osseointegration technology that introduce additional risks, higher costs, and longer periods of rehabilitation....
