Researchers compared whole-brain resting-state functional connectivity in 21 people with generalized anxiety disorder (GAD), 18 people with panic disorder (PD), and 22 matched healthy controls. They used a new measure called scaled correlation to look for differences across the brain. GAD showed stronger connections between the hippocampus/parahippocampus and the fusiform…
This randomized, double-blind, placebo-controlled crossover study gave subanesthetic S‑ketamine to 24 healthy young people while recording fMRI and EEG at rest. After ketamine, fMRI showed less connectivity in the medial prefrontal cortex and more connectivity in left and right intraparietal (parietal) areas of the default mode network. EEG showed more…
This paper is a systematic review and meta-analysis of resting-state fMRI studies that compared people with diagnosed anxiety disorders to healthy controls. The authors searched 1,226 records and then ran a coordinate-based meta-analysis (ALE) only on seed-based rs-fMRI studies because other study types were too few. The meta-analysis found reduced…
