Perinatal Dönemde Farklı Müzik Türlerine Maruz Kalmanın Genç Yaştaki Sıçanların Motor Aktiviteleri Üzerine Etkileri

Amaç: Bu çalışmada perinatal dönemde maruz kalınan müziğin, sıçan yavrularının motor koordinasyon ve aktiviteleri üzerindeki etkisini incelemek amaçlanmıştır. Gereç ve Yöntem: Wistar albino sıçanlara gebeliğin 10. gününden doğum yaptıkları güne kadar ve yavrulara doğumdan sonraki 2. günden 21. güne kadar klasik, tasavvuf veya metal müzik türlerinden herhangi biri günde 1 saat dinletildi. Uygulanan müzik türleri seçilirken müzik formlarının, stres veya sakinlik oluşturabilecek özellikte olması dikkate alındı. Sonrasında hem dişi hem de erkek yavrulara sırasıyla tutunma kapasitesi, görsel konumlandırma, doğrulma refleksi, eğimli tel, kirişte yürüme ve rotarod gibi motor koordinasyon testleri uygulandı. Bulgular: Metal grubunda bulunan dişi yavruların telde asılı kalma süreleri diğer gruptaki yavrulara oranla ve kendi grubundaki erkek yavrulara oranla anlamlı derecede yüksek bulundu. Diğer taraftan, klasik grubunda bulunan erkek yavruların kontrol grubunda bulunan erkek yavrulara oranla eğimli tel testinde tepeye ulaşma sürelerinde bir gecikme gözlemlendi. Aynı şekilde kirişte yürüme testinde bitiş noktasına ulaşma süresi kontrol grubundaki dişi yavrularla kıyaslandığında, klasik grubundaki dişi yavrularda daha uzundu. Kirişte yürüme testinde tasavvuf grubundaki hem dişi hem de erkek yavrular bitiş noktasına daha kısa sürede ulaştılar. Rotarod testinde ise hem klasik grubunda bulunan erkek yavruların hem de metal grubunda bulunan erkek yavruların kontrol grubunda bulunan erkek yavrulara oranla motor koordinasyonlarında bir düşüş saptandı. Sonuç: Elde edilen sonuçlara göre metal müzik dişilerde motor becerileri geliştirirken erkeklerde motor fonksiyonlarda bir düşüşe sebep olmaktadır. Klasik müzik ise her iki cinsiyette de harekete başlama ve sonuca ulaşma konusunda bir gecikmenin oluşmasına sebep olurken daha dingin bir müzik olan sufi müzik ise motor fonksiyonlarda gelişmeye sebep olmaktadır.

Effects of Exposure to Different Types of Music on Motor Activity in Juvenile Stage of Rat Pups During Perinatal Period

Objective: The present study was aimed to examine the effects of perinatal music exposure on the motor coordination and activity of rat pups. Material and Method: Wistar albino rats were exposed to different types of music (metal, classical, sufi) from gestational day 10 to birth and from postnatal day 2 to postnatal day 21 for 1h/day. Music preferences were done by taking stress or calmness factor into consideration. On the weaning period, motor coordination tests such as wire rod, visual placing, righting reflex, inclined screen, beam walking, and rotarod tests were applied to the both male and female rat pups. Results: Female pups in the metal group had significantly higher duration of hanging in wire rod test compared to male pups in the metal group and other music groups. In inclined screen test, male pups in the classical group had delayed on reaching top compared to male pups in the control group. Female pups in the classical group had longer time to reach at the end point compared to female pups in the control group. In this test, both female and male pups in the sufi group had shorter time to cross the beam. Male pups in the classical and the metal groups had lower performance than male pups in the control group. Conclusion: Results showed that exposure to metal music during pregnancy enhanced motor coordination in females but showed decrease performance in male pups. While classical music caused delays on starting an action and reaching at the end, sufi music enhanced motor functions on both sexes.
