Chronically Implanted Intracranial Electrodes: Tissue Reaction and Electrical Changes

open access: yesMicromachines, 2018
The brain-electrode interface is arguably one of the most important areas of study in neuroscience today. A stronger foundation in this topic will allow us to probe the architecture of the brain in unprecedented functional detail and augment our ability ...

The Relationship Between Reaction Time of Electrical Stapedius Reflex and Auditory Performance in Cochlear-implanted Children [PDF]

open access: yesIranian Rehabilitation Journal, 2021
Objectives: A common concern in some cochlear-implanted children is the lack of desired progress in auditory and listening skills. Such a concern remains despite proper verbal processor programming, additional disabilities, and continuous participation ...

Epidural Spinal Electrogram Provides Direct Spinal Recordings in Awake Human Participants

open access: yesFrontiers in Human Neuroscience, 2021
Little is known about the electrophysiological activity of the spinal cord during voluntary movement control in humans. We present a novel method for recording electrophysiological activity from the human spinal cord using implanted epidural electrodes ...

Feasibility of simultaneous intracranial EEG-fMRI in humans: a safety study [PDF]

open access: yes, 2010
In epilepsy patients who have electrodes implanted in their brains as part of their pre-surgical assessment, simultaneous intracranial EEG and fMRI (icEEG-fMRI) may provide important localising information and improve understanding of the underlying ...

The wear behaviour of ion implanted biomaterials [PDF]

open access: yes, 2003
The tribological performance of biomaterials used for artificial joints is of much importance, and require low coefficients of friction, resistance to wear and the ability to withstand many millions of cycles under a multitude of loading regimes ...

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.
