HELT and Tinnitus: One possibility to explain how the different rTMS protocols caused similar behavioral outcomes despite different changes in MGN activity is that stimulation of PFC ameliorated the behavioral signs of tinnitus after iTBS treatment independently of MGN, possibly via a direct pathway linking PFC and auditory cortex (Pandya and Kuypers, 1969; Petrides and Pandya, 1988; Winkowski et al., 2018).
