Grip control and motor coordination with implanted and surface electrodes while grasping with an osseointegrated prosthetic hand

Journal of NeuroEngineering and Rehabilitation, 2019
Background Replacement of a lost limb by an artificial substitute is not yet ideal. Resolution and coordination of motor control approximating that of a biological limb could dramatically improve the functionality of prosthetic devices, and thus reduce ...

Accuracy and Workflow Improvements for Responsive Neurostimulation Hippocampal Depth Electrode Placement Using Robotic Stereotaxy

Frontiers in Neurology, 2020
Background: Robotic stereotaxy is increasingly common in epilepsy surgery for the implantation of stereo-electroencephalography (sEEG) electrodes for intracranial seizure monitoring. The use of robots is also gaining popularity for permanent stereotactic

Transcranial Electric Stimulation Entrains Cortical Neuronal Populations in Rats [PDF]

, 2010
Low intensity electric fields have been suggested to affect the ongoing neuronal activity in vitro and in human studies. However, the physiological mechanism of how weak electrical fields affect and interact with intact brain activity is not well ...

Implantation and reimplantation of intracranial EEG electrodes in patients considering epilepsy surgery

Epilepsia Open, 2023
In patients with drug‐resistant epilepsy who are considering surgery, intracranial EEG (iEEG) helps delineate the putative epileptogenic zone. In a minority of patients, iEEG fails to identify seizure onsets.

Functional MRI during hippocampal deep brain stimulation in the healthy rat brain [PDF]

, 2015
Deep Brain Stimulation (DBS) is a promising treatment for neurological and psychiatric disorders. The mechanism of action and the effects of electrical fields administered to the brain by means of an electrode remain to be elucidated.

Multilayer 3D electrodes for neural implants [PDF]

Journal of Neural Engineering, 2019
In many applications, multielectrode arrays employed as neural implants require a high density and a high number of electrodes to precisely record and stimulate the activity of the nervous system while preserving the overall size of the array.Here we present a multilayer and three-dimensional (3D) electrode array, together with its manufacturing method,

Scaling of Electrode-Electrolyte Interface Model Parameters In Phosphate Buffered Saline [PDF]

, 2014
We report how the impedance presented by a platinum electrode scales with the concentration of phosphate buffered saline (PBS). We find that the constant phase element of the model scales with approximately the log of concentration, whereas the ...

Evaluating the Longevity of Implantable Pulse Generator Used in Deep Brain Stimulation: A Systematic Review

Iranian Journal of Neurosurgery, 2022
Background and Aim: Deep Brain Stimulation (DBS) surgery is increasingly performed to treat movement disorders. In these patients, a rechargeable or non-rechargeable battery is placed under their subcutaneous chest after implantation of an electrode in ...
