Gamma-Aminobutyric acid (GABA) is the major neurotransmitter for fast inhibitory synaptic transmission. Gabapentin which is recently introduced as an antiepileptic drug has been shown to modulate the GABA concentration in vivo in the brain. In this study, using MEGA PRESS based GABA editing sequence at 7T, we demonstrated the feasibility of measuring elevated GABA levels in response to gabapentin administration in healthy volunteers.
