    Effects of various intervals applied in classical music on the ultrastructure of reflector nerve and muscle terminals (A musical, medical, biological and experimental study)
    (2008) Mamedova L.; Metin I.; Ekici, N.; Huseyinov, M.; Huseyinova G.; Güner, S.S.
    The aim of the study was to explore the effects of these intonations on the reflector nerve and muscle terminals of guinea pigs using electron microscopic approaches. Spazmatic shrinking of myocyte myofibrils together with degenerative changes in myocytes and nerve terminals occur with the application of strained intonations. Transmission function is also damaged related with this situation. Clear relaxative extensions in myocyte myofibrils and decrease in activity of nerve terminals were determined with the application of more extensive intonations. © 2008 Academic Journals Inc.

    Study of ultrastructural changes on the cochleae caused by various intonations used in classical music
    (2008) Mamedova L.; Kanter, M.; Güner, S.S.; Bulut, E.; Mercantepe, T.; Metin I.; Hüseyinova G.; Aktaş, C.; Ekici, N.
    The aim of this study is to investigate the differences on ultrastructure of the cochleae caused by different classic musical opuses with different intonations. Guinea pigs were grouped into 3, one of which was the control and the other two were the experimental groups. While the first group, which was the control, was not exposed to any music, the second group was exposed to classic musical opuses with extensive intervals (40 decibel) and third group was exposed to classical music opuses with strained intonations (60 decibel) for 6 h a day with 15 min-intervals for totally 10 days. Cochleae tissue samples were taken from the guinea pigs at the end of the tenth day. They were examined at the electron microscopic level. In addition to compansatris processes on the cochleae, thickening on the stereocilias of hair cells and basal membranes and proliferation on the synaptic terminalles of afferent nerves caused by extensive intonations were observed. Extremely obvious degenerative differences such as damage in neuroepitelial cells, nerves and synaptic terminalles as well as compansatris processes caused by strained intonations were determined. As a result of all these observations it was concluded that continuously listening to the strained intonations used in musical opuses has a very harmful effect on the auditory system. © 2008 Academic Journals Inc.
