Glutamic acid and glutamic acid diethylester in tinnitus treatment.

Numerous recent findings indicate that in mammals glutamic acid (Glu) functions as the primary and secondary afferent cochlear transmitter, or at least as an agonist of the main transmitter. Glutamic acid diethylester (GDEE) is one of the known antagonists of Glu. A long term suppression of certain forms of tinnitus was observed dependent on the sequence, amount and perfusion rate upon i.v. application of Glu and GDEE. Consecutive controls with tinnitus detecting as well as blind studies helped to objectify the subjective sensations of the patients.

The influence of attention on the auditory brain stem evoked responses. Preliminary report.

The purpose of this study was to investigate the effects of attention on the auditory brainstem evoked responses (ABER). This was performed by measuring and statistically evaluating the interpeak latency times of wave I to wave V in 100 test subjects. The subjects were tested in three conditions: 1) selective attention to auditory click stimulation, 2) distraction by auditory stimuli, and 3) reinforced distraction by reading a newspaper during the click stimulations. It was observed that selective attention to the auditory stimulation leads to a decrease in the interpeak latency time (I-V) of, on the average, 0.2 milliseconds (statistically significant, 1%) in comparison with conditions 2 and 3.
