Physiology and Morphological Correlates of Excitatory Transmission are Preserved in Glutamine Transporter SN1-Depleted Mouse Frontal Cortex

•Excitatory transmission is preserved in glutamine transporter SN1 depleted mouse frontal cortex.•SN1 transporter loss resulted in a centrally located unaltered number of synaptic vesicles.•SN1 transporter depletion resulted in the unchanged length of the active zone in synapses.•Synaptic proteins synaptophysin, synaptotagmin, and vit1A weren’t affected by SN1 decrease.
