Millisecond-scale motor encoding in a cortical vocal area [PDF]

arXiv, 2014
Studies of motor control have almost universally examined firing rates to investigate how the brain shapes behavior. In principle, however, neurons could encode information through the precise temporal patterning of their spike trains as well as (or instead of) through their firing rates. Although the importance of spike timing has been demonstrated in

Spatial localization of sources in the rat subthalamic motor region using an inverse current source density method

Frontiers in Neural Circuits, 2016
Objective: In this study we introduce the use of the current source density (CSD) method as a way to visualize the spatial behavior of evoked responses in the rat subthalamic nucleus (STN) at fixed time stamps resulting from motor cortex stimulation ...

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

Advanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

Hierarchical Bayesian estimation of motor-evoked potential recruitment curves yields accurate and robust estimates [PDF]

arXiv
Electromagnetic stimulation probes and modulates the neural systems that control movement. Key to understanding their effects is the muscle recruitment curve, which maps evoked potential size against stimulation intensity. Current methods to estimate curve parameters require large samples; however, obtaining these is often impractical due to ...

Bioprinted Micro‐Clots for Kinetic Analysis of Endothelial Cell‐Mediated Fibrinolysis

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper describes the development of a microscale model that quantifies the breakdown of fibrin by endothelial cells. The small size scale of this engineered system enables fibrin breakdown to be observed without the addition of external activators. This system could help in identifying compounds which both promote and hinder thrombosis.

Sub-Scalp EEG for Sensorimotor Brain-Computer Interface [PDF]

arXiv
Objective: To establish sub-scalp electroencephalography (EEG) as a viable option for brain-computer interface (BCI) applications, particularly for chronic use, by demonstrating its effectiveness in recording and classifying sensorimotor neural activity. Approach: Two experiments were conducted in this study.

Transferability of cathodal tDCS effects from the primary motor to the prefrontal cortex: A multimodal TMS-EEG study

Brain Stimulation, 2023
Neurophysiological effects of transcranial direct current stimulation (tDCS) have been extensively studied over the primary motor cortex (M1). Much less is however known about its effects over non-motor areas, such as the prefrontal cortex (PFC), which ...

Liquid Crystalline Networks Hamper the Malignancy of Cancer Cells

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Liquid Crystalline Networks are used as scaffolds for the growth of A375 melanoma cells demonstrating to affect their malignancy. Indeed, only by contact, these materials reduces cell proliferation and colony formation capacity, while increasing the number of senescent cells and promoting the mesenchymal to epithelial transition.

How transcranial direct current stimulation facilitates post-stroke rehabilitation [PDF]

arXiv, 2019
Whether transcranial direct current stimulation (tDCS) benefits stroke rehabilitation remains unclear. To investigate how tDCS reorganizes brain circuitry, nineteen post-stroke patients underwent rehabilitation sessions with bi-hemispheric real vs sham tDCS intervention. Resting motor threshold measurements showed tDCS evoked higher excitability in the
