Cochlear implant users show weaker inter-hemispheric resting connectivity than normal-hearing listeners

Evidence

All NH listeners tested to date have shown particularly strong connectivity between analogous regions in left and right hemispheres, consistent with other studies using fNIRS (Medvedev 2014 ). In contrast, the CI users in this group have consistently shown lower inter-hemispheric connectivity than the NH listeners. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4305
