Deep transcranial magnetic stimulation (dTMS) has been recently used in several clinical studies as diagnostic and therapeutic tool. However, electric field (E) distributions induced the brain by dTMS are still unknown. This paper provides a characterization of E realistic human model due to 16 different coil configurations.The scalar potential finite-element method was calculate differentiating structures, e.g., cortex, white matter, anterior cingulated cerebellum, thalamus, hypothalamus,...
Radiofrequency electromagnetic fields originate from a variety of wireless communication sources operating near and far the body, making it challenging to quantify daily absorbed dose. In framework prospective cohort SCAMP (Study Cognition, Adolescents Mobile Phones), we aimed characterize RF-EMF dose over 2-year period. The included 6605 children greater London, UK at baseline (age 12.1 years; 2014–2016) 5194 follow-up 14.2; 2016–2018). We estimated eight tissues including whole body brain,...
Abstract The specific absorption rate (SAR) induced by wireless radiofrequency (RF) systems depends on different parameters. Previously, SAR was mainly assessed under conditions of a single frequency and technology for limited number localized RF sources. current emerging mobile involve wider range usage scenarios are frequently used simultaneously, leading to combined exposures which almost no exposure evaluation exists. aim novelty this study is close gap knowledge developing new methods...
In this article, we discuss numerical aspects related to the accuracy and computational efficiency of dosimetric simulations, performed in context human exposure static inductive charging systems electric vehicles. Two alternative methods based on vector potential scalar formulations, respectively, are here considered for field computation highly detailed anatomical models. The results obtained by implementation both approaches discussed terms compliance assessment with ICNIRP guidelines...
A procedure to personalize the electrode stimulate specific cortical regions by transcranial electric stimulations has been recently proposed. This study aims assess distribution of field (E) induced tES via personalized (RePE) and nonpersonalized (ReNPE) electrode.We used two anatomical models on which we shaped placed RePE, based brain anatomy, ReNPE target bilateral primary motor (M1) or somatosensory cortex (S1) with reference occipital area in both cases. The effect shifts position also...
Transcranial direct current stimulation (tDCS) was recently proposed for the treatment of epilepsy. However, electrode arrangement this case is debated. This paper analyzes influence position anodal on electric field in brain. The simulation shows that moving anode from scalp to shoulder does not only cortex, but also deeper brain regions. decreases dramatically area without epileptiform activity.
In this paper, fetal exposure to uniform magnetic fields (MF) with different polarizations is quantified at 50 Hz. Numerical computations were performed on high‐resolution pregnant models 3, 7, and 9 months of gestational age (GA), that distinguish a high number tissues. Fetal whole‐body tissue‐specific induced electric ( E ) current densities J analyzed as function both the extremely low frequency field (ELF‐MF) polarization GA. Additionally, variation due changes in position was by means...
Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that delivers low intensity, to cortical areas facilitating or inhibiting spontaneous neuronal activity. This paper investigates how normal variations in anatomy may affect the flow through brain. was done by applying electromagnetic computational methods human models of different age and gender comparing electric field density amplitude distributions within tissues. Results this study showed general trend spatial...
To assess the association between estimated whole-brain and lobe-specific radiofrequency electromagnetic fields (RF-EMF) doses, using an improved integrated RF-EMF exposure model, brain volumes in preadolescents at 9–12 years old. Cross-sectional analysis aged from Generation R Study, a population-based birth cohort set up Rotterdam, The Netherlands (n = 2592). An model was used to estimate doses (mJ/kg/day) different sources including mobile Digital Enhanced Cordless Telecommunications...
Human exposure modelling is a complex topic, because in realistic scenario, several parameters (e.g., the source, orientation of incident fields, morphology subjects) vary and influence dose. Deterministic dosimetry, so far used to analyze human electromagnetic fields (EMF), highly time consuming if previously-mentioned variations are considered. Stochastic dosimetry an alternative method build analytical approximations at lower computational cost. In this study, it was assess magnetic flux...
This paper addresses unresolved issues related to the safety of persons with conductive medical implants exposed electromagnetic (EM) fields. When EM fields compatible reference limits-in particular <100 MHz-implants may enhance local and energy absorption values much higher than basic restrictions that are considered safe. A mechanistic model based on transfer functions has been postulated for elongated active at magnetic resonance imaging (MRI) frequencies used as a basis standards dealing...
This work aimed to estimate the distribution of electric field and current density generated by cerebellar tDCS using electromagnetics computational techniques applied a realistic human models different ages gender. Results show that stronger occur mainly in cortex, with spread toward occipital region while other structures is negligible. Moreover, changes about 1 cm position scalp electrode delivering did not influence E J cerebellum.
Exposure to electromagnetic fields (EMFs) has prominently increased during the last decades due rapid development of new technologies. Among various devices emitting EMFs, those based on Radio-frequency identification (RFID) technologies are used in all aspects everyday life, and expose people unselectively. This scenario could pose a potential risk for some groups general population, such as pregnant women, who expected be possibly more sensitive thermal effects produced by EMF exposure. is...

Extremely low frequency magnetic fields (ELF-MFs) exposure is still a topic of concern due to their possible impact on children's health. Although epidemiological studies claimed an evidence association between ELF-MF above 0.4 μT and childhood leukemia, biological mechanisms able support causal relationship this disease were not found yet. To provide further knowledge about correlated daily activities, measurement study was conducted in Milan (Italy). Eighty-six children recruited, 52 whom...
