Characterization of the Stages of Creative Writing With Mobile EEG Using Generalized Partial Directed Coherence

open access: yesFrontiers in Human Neuroscience, 2020
Two stages of the creative writing process were characterized through mobile scalp electroencephalography (EEG) in a 16-week creative writing workshop. Portable dry EEG systems (four channels: TP09, AF07, AF08, TP10) with synchronized head acceleration ...

Non-invasive electroretinography

open access: yesBiomedicine & Pharmacotherapy, 2006
Electroretinographic (ERG) investigations are conventionally performed by using corneal or conjunctival recording electrodes. Both types have to be placed in contact with the eye, resulting invasive and providing discomfort for the patient. This paper presents a simple technique to detect ERG potentials non-invasively.

Left ventricular concentric geometry predicts incident diabetes mellitus independent of established risk factors in the general population: the Copenhagen City Heart Study

open access: yesCardiovascular Diabetology, 2019
Background Subtle impairments in left ventricular (LV) function and geometry are common findings in individuals with diabetes. However, whether these impairments precede the development of diabetes mellitus (DM) is not entirely clear.

Transcranial Direct Current Stimulation Effects on the Neural Substrate of Conceptual Representations

open access: yesBrain Sciences, 2023
The aim of this study was to shed light on the neural substrate of conceptual representations starting from the construct of higher-order convergence zones and trying to evaluate the unitary or non-unitary nature of this construct.

Non invasive neurostimulation [PDF]

open access: yesThe Journal of Headache and Pain, 2015
Neurostimulation has been used in pain management for a long time. Several neuromodulatory surgical techniques were developed to manage headaches unresponsive to medical treatment, in particular for preventive treatment. Recently, novel non invasive neurostimulation approaches have been used successfully for different forms of headache: they represent ...

Perturbation of resting-state network nodes preferentially propagates to structurally rather than functionally connected regions

open access: yesScientific Reports, 2021
Combining Transcranial Magnetic Stimulation (TMS) with electroencephalography (EEG) offers the opportunity to study signal propagation dynamics at high temporal resolution in the human brain.

Preliminary study of the toxicity and radioprotective effects of zymosan in vitro and in vivo

open access: yesBMC Pharmacology and Toxicology, 2021
Background This study aimed to confirm the cytotoxicity of zymosan in vitro and in vivo and determine the appropriate treatment time and the dose of zymosan. Methods AHH-1 cells and HIECs were administered by 0, 20, 40, 80 or 160 μg/mL zymosan. The CCK-8
