A, Diagram illustrating the relative locations of stimulating electrodes for auditory cortex (AC) stimulation (left) and secondary somatosensory cortex (S2) stimulation (right). B, Cytochrome oxidase-stained section from same slice, demonstrating lack of barrel architecture in the region of cortical activation. SCWM, Subcortical white matter; R, rostral; C, caudal; L, lateral; M, medial. C, Example of a response in secondary somatosensory cortex to 200 μA stimulus to the subcortical white matter. D, Correlation between the magnitude of activation in the auditory cortex to the magnitude of activation in the somatosensory cortex in the same slices. Black circles, Noise-exposed animals; black triangles, sham-treated animals. R² and p values generated from Spearman's correlations.
