Miniaturized low-field thoracic magnetic stimulation device for assessing effects on peripheral oxygen saturation levels in healthy rats Open
Objective. This study aimed to develop a miniaturized low-field thoracic magnetic stimulation (LF-ThMS) device to evaluate its effects on peripheral oxygen saturation (SpO 2 ) in healthy rats. This investigation was motivated by prior find…

The Saks-Henstock Lemma and the Change of Variable Formula of the PU integral Open
Henstock integral is a generalized version of the Riemann integral and in most cases, it is more general than the Lebesgue integral that is not constructed through a measure theoretic standpoint. The PU integral, on one hand, is a Henstock…

Power spectral density and similarity analysis of COVID-19 mortality waves across countries Open
These findings could be helpful for planetary health if a future pandemic of a similar scale occurs so that effective confinement measures or other actions could be planned during these two identified periods.

Power spectra density and similarity analysis of COVID-19 mortality waves across countries Open
Johns Hopkins University CSSE documented waves of oscillatory COVID-19 mortality patterns worldwide during the COVID-19 pandemic. Here, we calculated the power spectrum density (PSD) of these COVID-19 mortality waves in 199 countries from …

Chronic pelvic inflammatory context leading to migraine exacerbation: a case report Open
Case presentation: Woman, 48 years old, infertile, with dysmenorrhea, episodic headache since the age of 35 with weekly attacks and worsening related to the menstrual cycle. In 2020, she developed a sudden onset of dyspnea and chest pain, …

Similarity index of ex-Gaussian reaction time signatures Open
In psychology and cognitive neuroscience, reaction time (RT) series and their ex-Gaussian distributions are commonly used to explore the time course of cognitive processes. This study investigated the hypothesis that successive triads of e…

Pharmacological characterization and differential expression of NMDA receptor subunits in the chicken vestibular system during development Open
Previous studies demonstrated that in vitro preparations of the isolated vestibular system of diverse animal species still exhibit stable resting electrical activity and mechanically evoked synaptic transmission between hair cells and prim…

Noisy Light Augments the Na+ Current in Somatosensory Pyramidal Neurons of Optogenetic Transgenic Mice Open
In previous reports, we developed a method to apply Brownian optogenetic noise-photostimulation (BONP, 470 nm) up to 0.67 mW on the barrel cortex of in vivo ChR2 transgenic mice. In such studies, we found that the BONP produces an i…

The Hemodynamic Mass Action of a Central Pattern Generator Open
The hemodynamic response is a neurovascular and metabolic process in which there is rapid delivery of blood flow to a neuronal tissue in response to neuronal activation. The functional magnetic resonance imaging (fMRI) and the functional n…

Afterdischarges of Spinal Interneurons Following a Brief High-Frequency Stimulation of Ia Afferents in the Cat Open
Spinal motoneurons exhibit sustained afterdischarges and plateau potentials following a brief high-frequency stimulation of Ia afferents. Also, there is evidence that spinal cord interneurons exhibit plateau potentials. However, to our kno…

Resetting the Respiratory Rhythm with a Spinal Central Pattern Generator Open
There is evidence that a variety of central and afferent stimuli, including swallowing, can produce phase resetting in the respiratory rhythmicity. Also, there are reports about the intrinsic linkage between locomotion and respiration. How…

Augmenting EEG-global-coherence with auditory and visual noise Open
The present investigation documents the electrophysiological occurrence of multisensory internal stochastic resonance (MISR) in the human electroencephalographic (EEG) coherence elicited by auditory and visual noise.We define MISR of EEG c…

Effect of mechanical tactile noise on amplitude of visual evoked potentials: multisensory stochastic resonance Open
The present investigation documents the electrophysiological occurrence of multisensory stochastic resonance in the human visual pathway elicited by tactile noise. We define multisensory stochastic resonance of brain evoked potentials as t…
