Error correction and fast detectors implemented by ultra-fast neuronal plasticity [PDF]

open access: yesPhys. Rev. E 89, 042712 (2014), 2014
We experimentally show that the neuron functions as a precise time-integrator, where the accumulated changes in neuronal response latencies, under complex and random stimulation patterns, are solely a function of a global quantity, the average time-lag between stimulations.

Extracellular stimulation window explained by a geometry-based model of the neuron-electrode contact [PDF]

open access: yes, 2002
Extracellular stimulation of single cultured neurons which are completely sealing a microelectrode is usually performed using anodic or biphasic currents of at least 200 nA.

Vagus Nerve Stimulation Affects Pain Perception in Depressed Adults

open access: yesPain Research and Management, 2005
BACKGROUND: Previous research suggests that vagus nerve stimulation (VNS) affects pain perception in epilepsy patients, with acute VNS decreasing pain thresholds and chronic VNS treatment increasing pain thresholds.

Effect of parasympathetic stimulation on brain activity during appraisal of fearful expressions [PDF]

open access: yes, 2015
Autonomic nervous system activity is an important component of human emotion. Mental processes influence bodily physiology, which in turn feeds back to influence thoughts and feelings.

Histological Analysis of Failed Cartilage Repair after Marrow Stimulation for the Treatment of Large Cartilage Defect in Medial Compartmental Osteoarthritis of the Knee [PDF]

open access: yes, 2013
Bone marrow-stimulating techniques such as microfracture and subchondral drilling are valuable treatments for full-thickness cartilage defects. However, marrow stimulation-derived reparative tissues are not histologically well-documented in human ...

Bifidobacteria and Butyrate-Producing Colon Bacteria: Importance and Strategies for Their Stimulation in the Human Gut

open access: yesFrontiers in Microbiology, 2016
With the increasing amount of evidence linking certain disorders of the human body to a disturbed gut microbiota, there is a growing interest for compounds that positively influence its composition and activity through diet.

Temporal Interference (TI) Stimulation Boosts Functional Connectivity in Human Motor Cortex: A Comparison Study with Transcranial Direct Current Stimulation (tDCS)

open access: yesNeural Plasticity, 2022
Temporal interference (TI) could stimulate deep motor cortex and induce movement without affecting the overlying cortex in previous mouse studies. However, there is still lack of evidence on potential TI effects in human studies.

Band power modulation through intracranial EEG stimulation and its cross-session consistency [PDF]

open access: yesJournal of Neural Engineering, 17-054001 (2020), 2020
Background: Direct electrical stimulation of the brain through intracranial electrodes is currently used to probe the epileptic brain as part of pre-surgical evaluation, and it is also being considered for therapeutic treatments through neuromodulation.

Setting reference level in the human safety guidelines via nerve activation intercomparison at IF [PDF]

open access: yes, 2019
International guidelines/standards have been published for human protection from electromagnetic field exposure. The research in the intermediate frequencies (IF: 300 Hz-10 MHz) is scattered unlike for other frequencies, and thus the limit prescribed in ...

Temporal dynamics of stimulated emission with applications in nuclear quantum optics [PDF]

open access: yesPhys. Rev. A 91, 053810 (2015), 2014
The temporal dynamics of stimulated emission is studied, with the particular emphasis on stimulated emission induced by x-ray pulses interacting with nuclei. In typical nuclear forward scattering experiments, the short incident x-ray pulse is accompanied by a huge number of off-resonant background photons.
