In this research visual stimulation was used for the first functional MRS of aspartate, TE averaging – for pure glutamate and glutamine, and MEGA-PRESS for GABA- to find activation-induced changes at 3 Tesla. The results (except for glutamine) are in compliance with previously published data for 7T. The parameters behavior might reflect the manifestation of Glu neurotransmitter function predominance and metabolic character of changes in the concentrations of other parameters studied.
