LFPy: A tool for biophysical simulation of extracellular potentials generated by detailed model neurons

Frontiers in Neuroinformatics, 2014
Electrical extracellular recordings, i.e., recordings of the electrical potentials in the extracellular medium between cells, have been a main work-horse in electrophysiology for almost a century. The high-frequency part of the signal (>=500 Hz), i.e.,

Removal of Electrocardiogram Artifacts From Local Field Potentials Recorded by Sensing-Enabled Neurostimulator

Frontiers in Neuroscience, 2021
Sensing-enabled neurostimulators are an advanced technology for chronic observation of brain activities, and show great potential for closed-loop neuromodulation and as implantable brain-computer interfaces.

Diurnal influences on electrophysiological oscillations and coupling in the dorsal striatum and cerebellar cortex of the anesthetized rat

Frontiers in Systems Neuroscience, 2014
Circadian rhythms modulate behavioral processes over a 24h period through clock gene expression. What is largely unknown is how these molecular influences shape neural activity in different brain areas.

Research on Active Obstacle Avoidance of Intelligent Vehicles Based on Improved Artificial Potential Field Method

World Electric Vehicle Journal, 2022
In the study of autonomous obstacle avoidance of intelligent vehicles, the traditional artificial potential field method has the problem that the vehicle may fall into the local minima and lead to obstacle avoidance failure.

Localized Path Planning for Mobile Robots Based on a Subarea-Artificial Potential Field Model

Sensors
The artificial potential field method has efficient obstacle avoidance ability, but this traditional method suffers from local minima, unreasonable paths, and sudden changes in heading angles during obstacle avoidance, leading to rough paths and ...

Increased slow oscillatory activity in substantia nigra pars reticulata triggers abnormal involuntary movements in the 6-OHDA-lesioned rat in the presence of excessive extracelullar striatal dopamine

Neurobiology of Disease, 2006
Since electrophysiological correlates of l-dopa-induced dyskinesia (LID) are almost unknown, changes of striatal dopamine (DA) transmission and electrophysiological activity of the substantia nigra pars reticulata (SNr) were recorded before and after ...

Modeling Spectral Properties in Stationary Processes of Varying Dimensions with Applications to Brain Local Field Potential Signals

Entropy, 2020
In some applications, it is important to compare the stochastic properties of two multivariate time series that have unequal dimensions. A new method is proposed to compare the spread of spectral information in two multivariate stationary processes with ...

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Whisker Array Functional Representation in Rat Barrel Cortex:Transcendence of One-to-One Topography and its Underlying Mechanism

Frontiers in Neural Circuits, 2012
The one-to-one relationship between whiskers, barrels, and barrel columns described for rat barrel cortex demonstrates that the organization of cortical function adheres to topographical and columnar principles. Supporting evidence is typically based on

Melamine Disrupts Acetylcholine-Mediated Neural Information Flow in the Hippocampal CA3–CA1 Pathway

Frontiers in Behavioral Neuroscience, 2021
Considering the cognitive and synaptic deficits following intragastric administration of melamine, the aim of the current investigation was to test whether the hippocampal oscillations were affected.
