Two-State Effective Connectivity Predicts the effect of Anterior Cingulate Cortex Excitatory / Inhibitory Balance on Posterior Cingulate Cortex
Aims Excitatory/inhibitory imbalance - the equilibrium between glutamatergic excitation and {gamma}-Aminobutyric acid (GABA)ergic inhibition - is implicated in psychosis and may precede psychosis onset. Methods To investigate whether excitatory/inhibitory balance relates to subclinical psychotic experiences, anxiety and depression, we developed a network-level measure integrating Magnetic…
