The anterior cingulate cortex (ACC), a core hub of this network, has shown alterations in the major neurotransmitter systems comprising glutamate (Glu) and \u03b3-aminobutyric acid (GABA). While dysfunctional glutamatergic signaling has been proposed as a key mechanism in SSDs, the relationship between anterior cingulate cortex (ACC) functional connectivity, glutamatergic neurotransmission, and clinical symptomatology remains poorly understood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0924933826122123_sec2\" sec-type=\"methods\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Here, we combined resting-state functional MRI to measure functional brain connectivity with proton magnetic resonance spectroscopy to measure Glu and GABA levels in the dorsal ACC of 26 patients with schizophrenia spectrum disorders and 38 healthy controls.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0924933826122123_sec3\" sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Patients showed reduced connectivity within the salience network compared to controls.
