Fig. 2
Sensor level field topographies for a 1 nAm current dipole simulated in the thoracic region of the spine (approximately T9; see red dot of bottom right panel) when the sources are oriented along the anterior/posterior (A–P) axis of the body (top row), right/left (R–L) axis (middle row) and inferior/superior (I–S) axis (bottom row). The plots are sorted into channels with a common orientation in rows. X and Z (left and right columns) represent channels oriented tangential to the surface of the back whilst Y (middle column) represents the channels oriented normal to the back. Black dots represent sensor locations and black lines represent field contour lines (separating undeciles of field strength). Similar plots for other conductive models can be found in Supplementary Information.
