Identification of taste quality with the use of meg.
We investigated the localization of current sources for spontaneous magnetoencephalographic (MEG) data in the frequency domain. MEGs were evaluated in three different states: (i) physiological condition; (ii) sweet taste, and (iii) salt taste. Low frequencies can be seen in the maps obtained with the sweet taste, whereas in the physiological and salt taste, the maps show higher frequencies in the majority of channels. A differentiation in the spatial distribution of the frequencies provides novel insights into the identification of taste quality with the MEG systems.
