Schematic diagram illustrating the organization of ipsilateral and contralateral tectothalamic inputs to the IC. As demonstrated in this study, the mouse MGB receives both ascending excitatory (green) and inhibitory (red) inputs from the ipsilateral and contralateral IC. In addition, the contralateral IC could potentially influence the ipsilateral MGB via indirect projections through the IC commissure that target ascending ipsilateral tectothalamic projections [31]. The MGB itself integrates these inputs with inhibitory inputs from the thalamic reticular nucleus (TRN) and excitatory inputs from layer 6 of the auditory cortex (AC) [47,48,49,50].
