in march 2004, a fluxgate gradiometer survey was conducted over tepe ghabristan, covering approximately 6ha of ground. it identified further areas of the iron age cemetery with possible grave pits (areas b and c). in addition, an irrigation channel was discovered which could be contemporary to these iron age graves (area d). the anomalies in area e can be interpreted as buried structural remain...

The system has been demonstrated over a magnetite skarn deposit at Tallawang, near Gulgong, NSW, which is essentially two-dimensional (2D). The 2D structure was important because it allowed an unaliased total magnetic intensity (TMI) survey to be carried out in parallel, from which tensor components could be calculated to directly compare with the tensor components measured with the rotating gr...

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...
