Cover Story: Following noise trauma, the recording of auditory brainstem-evoked potentials, the behavioural confirmation of tinnitus, and the simultaneous implantation of microdialysis probes in the cochlear nucleus (CN) and auditory cortex (AC) of rats were carried out. HPLC with ECD was then used to measure the concentrations of seven amino acids. Although there were no significant differences in the basal- or sound-evoked levels of any amino acid in the CN or AC between the sham and tinnitus rats, the basal serine and threonine showed significant age-related changes within the AC. Significant differences were also found in the threonine and glycine levels in response to the 4 and 16 kHz stimuli within the CN. These results demonstrate the absence of a direct link between the extracellular levels of amino acids in the CN and AC and tinnitus. View this paper
