Contralateral parahippocampal gamma-band activity determines noise-like tinnitus laterality: a region of interest analysis

▶Unilateral tinnitus is generated in the left auditory cortex, irrespective of the tinnitus side. ▶Unilateral tinnitus is always generated in the contralateral auditory cortex. ▶Tinnitus lateralization depended on the contralateral parahippocampal area. ▶In auditory cortex no differences were found between left- and right-sided tinnitus patients.
