<p>Hair cells of the inner ear transduce mechanical stimuli like sound or head movements into electrical signals, which are propagated to the central nervous system. The hair-cell mechanotransduction channel remains unidentified. We tested whether three transient receptor channel (TRP) family members, TRPV6, TRPM6 and TRPM7, were necessary for transduction. TRPV6 interacted with USH1C (harmonin), a scaffolding protein that participates in transduction. Using a cysteine-substitution knock-in mouse line and methanethiosulfonate (MTS) reagents selective for this allele, we found that inhibition of TRPV6 had no effect on transduction in mouse cochlear hair cells. TRPM6 and TRPM7 each interacted with the tip-link component PCDH15 in cultured eukaryotic cells, which suggested they might be part of the transduction complex. Cochlear hair cell transduction was not affected by manipulations of Mg²⁺, however, which normally perturbs TRPM6 and TRPM7. To definitively examine the role of these two channels in transduction, we showed that deletion of either or both of their genes selectively in hair cells had no effect on auditory function. We suggest that TRPV6, TRPM6 and TRPM7 are unlikely to be the pore-forming subunit of the hair-cell transduction channel.</p

Power and Phase Locking Results for Controls and Patients with Schizophrenia.

<p>Upper panel: time-frequency power spectrum (ERSP) from the Fz electrode for Controls and Patients. The significant time-frequency segment overlapping in time with the MMN is marked with a black box in the figures (~3-6 Hz, around 200 ms). Lower panel: time-frequency phase-locking factor (PLF) for groups. Inserts in each panel show the topographic distribution of power and phase-locking values across all the electrodes.</p

MMN waveforms and topographic headplots.

<p>First row: Standard and deviant waveforms from electrode Fz for Controls and Patients. Second row: MMN waveforms from electrode Fz for Controls and Patients. Significant differences were found in the marked (170-210ms) time interval. Third row: topographic headplots for two groups and their difference from the significant time interval (170-210ms). Electrodes with significant effects are marked by white disks. Fourth row: Difference waves from the mastoid electrodes.</p
