Decoding Local Field Potentials for Neural Interfaces [PDF]

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2017
The stability and frequency content of local field potentials (LFPs) offer key advantages for long-term, low-power neural interfaces. However, interpreting LFPs may require new signal processing techniques which should be informed by a scientific understanding of how these recordings arise from the coordinated activity of underlying neuronal ...

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding

Variability of seizure-like activity in an in vitro model of epilepsy depends on the electrical recording method

Heliyon, 2020
Background: Hippocampal and cortical slice-based models are widely used to study seizures and epilepsy. Seizure detection and quantification are essential components for studying mechanisms of epilepsy and assessing therapeutic interventions.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Profiling the low-beta characteristics of the subthalamic nucleus in early- and late-onset Parkinson’s disease

Frontiers in Aging Neuroscience, 2023
ObjectivesLow-beta oscillation (13–20 Hz) has rarely been studied in patients with early-onset Parkinson’s disease (EOPD, age of onset ≤50 years).

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Computing the Local Field Potential (LFP) from Integrate-and-Fire Network Models.

PLoS Computational Biology, 2015
Leaky integrate-and-fire (LIF) network models are commonly used to study how the spiking dynamics of neural networks changes with stimuli, tasks or dynamic network states. However, neurophysiological studies in vivo often rather measure the mass activity

Subthalamic Stimulation Inhibits Bladder Contraction by Modulating the Local Field Potential and Catecholamine Level of the Medial Prefrontal Cortex

Frontiers in Neuroscience, 2020
AimsThe patients with Parkinson’s disease (PD) present with lower urinary tract symptoms (LUTS), but the efficacy of subthalamic nucleus deep brain stimulation (STN-DBS) on LUTS is unknown.

The decoupling between hemodynamic parameters and neural activity implies a complex origin of spontaneous brain oscillations

Frontiers in Computational Neuroscience, 2023
IntroductionSpontaneous low-frequency oscillations play a key role in brain activity. However, the underlying mechanism and origin of low-frequency oscillations remain under debate.MethodsOptical imaging and an electrophysiological recording system were ...

A note on the post-Newtonian limit of quasi-local energy expressions

, 2011
An `effective' quasi-local energy expression, motivated by the (relativistically corrected) Newtonian theory, is introduced in exact GR as the volume integral of all the source terms in the field equation for the Newtonian potential in static spacetimes.
