Intracortical microstimulation (ICMS) of somatosensory cortex evokes tactile sensations whose properties can be systematically manipulated by varying stimulation parameters. However, ICMS currently provides an imperfect sense touch, limiting manual dexterity and experience. Leveraging our understanding how features are encoded in the primary (S1), we sought to inform individuals with paralysis about local geometry apparent motion objects on their skin. We simultaneously delivered through...
Abstract Objective . In electrophysiology, microelectrodes are the primary source for recording neural data (single unit activity). These can be implanted individually or in form of arrays containing dozens to hundreds channels. Recordings some channels contain activity, which often contaminated with noise. Another fraction does not record any data, but only By noise, we mean physiological activities unrelated spiking, including technical artifacts and neurons that too far away from...
Objective. Advancements in electrode design have resulted micro-electrode arrays with hundreds of channels for single cell recordings. In the resulting electrophysiological recordings, each implanted can record spike activity (SA) one or more neurons along background (BA). The aim this study is to isolate SA neural source. This process called sorting classification. Advanced algorithms are time consuming because human intervention at various stages pipeline. Current approaches lack...
Intracortical microstimulation (ICMS) of somatosensory cortex evokes tactile sensations whose location and properties can be systematically manipulated by varying the electrode stimulation parameters 1–3 . This phenomenon used to convey feedback from a brain-controlled bionic hand about object interactions. However, ICMS currently provides an impoverished sense touch, limiting dexterous manipulation conscious experience neuroprosthetic systems. Leveraging our understanding how these sensory...
In electrophysiology, microelectrodes are the primary source for recording neural data of single neurons (single unit activity). These can be implanted individually, or in form arrays, consisting hundreds electrodes. During recordings, some channels capture activity neurons, which is usually contaminated with external artifacts and noise. Another considerable fraction does not record any data, but Therefore, an automatic identification tracking containing great significance accelerate...
Abstract Invasive brain–computer-interfaces (BCIs) aim to improve severely paralyzed patient’s (e.g. tetraplegics) quality of life by using decoded movement intentions let them interact with robotic limbs. We argue that the performance in controlling an end-effector a BCI depends on three major factors: decoding error, missing somatosensory feedback and alignment error caused translation and/or rotation relative real or perceived body. Using virtual reality (VR) model ideal decoder healthy...
