Cover Picture: Axial view of the cortically-generated magnetic field of a human listener, measured using whole-head magnetoencephalography (MEG), at a single moment in time. Isofield contours in red (respectively, blue) indicate the strength of outward (inward) magnetic flux; the digitized scalp surface is in gray. For each hemisphere, a magnetic dipole-like pattern is centered over temporal cortex, and the neural generator itself, located in planum temporale, is an inferiorly flowing neuronal electric current. The MEG channels responding most strongly (in the center of each flux area) are designated by filled yellow circles. The acoustic stimulus is a 1 kHz pure tone; time is 100 ms post onset. The image is generated with the MEG160 software (Yokogawa electric corporation, KIT, Japan). See Chait, Poeppel, and Simon, pp. 835–848.
