Bilateral Heschl’s gyrus display non-reciprocity in connectivity during the performance of simple arithmetic addition task

Heschl’s gyrus (HG) is known to interact with other auditory related areas of the same hemisphere during the performance of an auditory cognitive task. However, the information about how it interacts with the opposite HG is still lacking. The aim of this study was to investigate the psychophysiolo...
