GABAergic inhibitory interneurons balance brain activity by suppressing excessive excitatory signaling and shaping network oscillations. Despite this critical function, our understanding of how neural circuits regulate GABAergic systems remains limited. Although N-methyl-D-aspartate receptor (NMDAR) functionality is defined by the GluN2A-D subunits, the interneuron NMDAR subunit composition...
Significance Standard antidepressant treatments require weeks to show effectiveness. A single subanesthetic dose of ketamine rapidly attenuates many clinical signs and symptoms of depression; however, ketamine treatment also has many adverse effects, including dissociation and potential for abuse, which are mediated by NMDA glutamate receptor (NMDAR) inhibition. Previous work has revealed that...
