The spatial relationship of electroencephalography (EEG) and magnetoencephalography (MEG) to brain activation is quantified as their cortical lead fields: the sensitivity of each sensor to activation of each cortical location. Here we map the lead fields of EEG and MEG across the cortical surface using a realistic boundary element model with four compartments. These calculations demonstrate tha...

Child development is seriously affected by social interactions with caregivers, which may lead to forming social minds in our daily life afterward. However, the underlying neural mechanism for such interactions has not yet been revealed. This article introduces a magnetoencephalographic (MEG) hyperscanning system to examine brain-to-brain interactions between a mother and her child. We used two...

Three new types of fluxgate magnetometers are presented in this paper, able to monitor the three components of the ambient field, all of them based on the principle of rotational excitation field. The first type is based on YttriumIron Garnet (YIG) single crystal film, magnetized with rotational field on its plane, where the 2 nd , 4 th and 6 th harmonics offer the three components of the ambie...

Introduction. The article describes the optimization of superconducting antenna design and balancing method magnetometer. This magnetometer is designed to study magnetic properties materials, as well non-invasive distribution particles in organs small laboratory animals, when toxic or drugs are introduced into animal's body. a second-order axial gradiometer part flux transformer SQUID sensor. F...
