Non-SSA neurons primarily receive facilitatory influences from the AC. Example of a neuron recorded from the MGV that was facilitated by the AC, presented as in Figure 2. The neuron responds consistently to both the standard and the deviant over the trials, i.e., it does not show SSA as confirmed by the low CSI value (~0). The CSI value was not significantly changed by AC deactivation. AC, auditory cortex; MGV, ventral subdivision of the medial geniculate body; CSI, common SSA index.
