et al.

Abstract: This multimodal brain imaging study investigated functional MRI (fMRI) neural processing of cardiac interoceptive signals in 38 patients with functional neurological disorder (FND) compared to 38 healthy controls (HCs). Additionally, we characterized how brain fMRI responses during heartbeat counting (interoception) vs. tone counting (exteroception) or rest related to grey matter volume, interoceptive awareness, and psychopathology scores. For both interoception vs. rest and interoception vs. exteroception con… Show more
