Time-varying EEG spectral power predicts evoked and spontaneous fMRI motor brain activity [PDF]

open access: yesarXiv
Simultaneous EEG-fMRI recordings are increasingly used to investigate brain activity by leveraging the complementary high spatial and high temporal resolution of fMRI and EEG signals respectively. It remains unclear, however, to what degree these two imaging modalities capture shared information about neural activity. Here, we investigate whether it is

Attenuation of Motor Evoked Potentials Following Prone Positioning

open access: yesIranian Journal of Neurosurgery, 2020
Background and Importance: Of utmost importance for the success of neurosurgical operations is proper patient positioning. This is particularly the case for operations conducted in the prone position, which is associated with several potential ...

Command Interneurons in the Crayfish Central Nervous System [PDF]

open access: yes, 1967
The motor effects evoked by stimulation of each of eight command fibres in the circumoesophageal commissures of the crayfish are described. The fibres obtained appeared to have widespread connexions in all or most of the lower ganglia. For certain fibres

Engineering Topographical Cues to Enhance Neural Regeneration in Spinal Cord Injury: Overcoming Challenges and Advancing Therapies

open access: yesAdvanced Functional Materials, EarlyView.
Spinal cord injury (SCI) poses significant challenges for regeneration due to a series of secondary injury mechanisms. How to use biomaterial approach to target the failed regeneration after SCI remains a critical challenge. This review systematically evaluates current strategies to optimize biomaterial topographies for neurite outgrowth, axonal ...

Obtaining single stimulus evoked potentials with Wavelet Denoising [PDF]

open access: yesPhysica D, 2000; 145: 278-292, 2000
We present a method for the analysis of electroencephalograms (EEG). In particular, small signals due to stimulation, so called evoked potentials, have to be detected in the background EEG. This is achieved by using a denoising implementation based on the wavelet decomposition.

Microglial Activation and Neurological Symptoms in the SIV Model of NeuroAIDS: Association of MHC-II and MMP-9 Expression with Behavioral Deficits and Evoked Potential Changes

open access: yesNeurobiology of Disease, 1999
HIV-1 causes cognitive and motor deficits and HIV encephalitis (HIVE) in a significant proportion of AIDS patients. Neurological impairment and HIVE are thought to result from release of cytokines and other harmful substances from infected, activated ...

A Bioengineered Model of the Human Cornea for Preclinical Assessment of Human Ocular Exposure to Environmental Toxicants

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper presents a microphysiological system containing an array of individually addressable living corneal tissues constructed using primary human cells. The bioengineered eye model can simulate acute exposure of the human cornea to different types of environmental toxicants and provides a novel platform for visualization and quantitative ...

Reduced Muscle Fatigue Using Continuous Subthreshold Kilohertz Stimulation of Peripheral Nerves [PDF]

open access: yesarXiv
Functional electrical stimulation (FES) is a prevalent technique commonly used to activate muscles in individuals with neurological disorders. Traditional FES strategies predominantly utilize low-frequency (LF) stimulation, which evokes synchronous action potentials, leading to rapid muscle fatigue.
