The most constant and most important BAEP waves from the clinical point of view are waves I, III & V. Their measurements include absolute latency and interpeak latency. The Interpeak latencies represent conduction time through relay stations of auditory pathway in the brainstem. Thus IPL I-III is a measure of conduction from acoustic nerve to pontomedullary region, III-V conduction in the more rostral pontine and midbrain portion of the pathway and I-V reflects the total brainstem conduction time. Concerning electrophysiological measures, it appears that at least for middle and late evoked potentials male and female differences appear in adulthood. There appears to be less agreement among researchers with respect to the age at which gender differences are evident with the auditory brainstem response. The aim of our study is to find out the effect of gender on BAEP waves latencies and amplitudes. We assigned one hundred and five subjects for study. Out of them 55 were males and 50 females between the age group of 20-35 years. Wave III and wave V latencies & I-III and I-V interpeak latencies were significantly (P < 0.01) shorter in females than in males. The difference in mean wave V latency between males & females was 0.18 ms. The significant changes in the BAEPs in our study support the possible role of gender as contributive factors for normal variations.
This paper describes our first undergraduate project experience, final report and findings on the subject matter. Initially according to our project title, we were focused on developing a low cost detector which can detect radiation only. To make one of these kinds of detector doesn’t take much and can be prepared at fairly low cost being very common project in nuclear science arena. The Geiger-Muller tube, or GM tube, is an extremely useful and inexpensive way to detect radiation. While the GM tube can only detect the presence and intensity of radiation, this is often all that is needed.
