The Difference of Exposure Effect of the Mozart, Javanese, Sundanese and Balinese Gamelan Music During Pregnancy to the Number of Neuronal Cells on Cerebrum and Cerebellum of Offspring Rattus Norvegicus

Abstract

Background: Improve the human resource requires good brain quality since the phase of conception.
Offering stimulus with classical music and regional music (gamelan) which is believed can help to boost
the brain cells and intellectual intelligence. Exposure to Mozart’s music, Javanese, Sundanese and Balinese
gamelan affects the number of neuron cells.
Objective: Analyze the different of the number of neuronal cells on cerebrum and cerebellum offsprings
Rattus norvegicus from mothers were exposed with Mozart music, Javanese Gamelan, Sundanese, Balinese
and not exposed to music during pregnancy.
Method: This study was a experimental study with post test only control group design. The samples were
divided randomly into 5 groups. The treatments were given the 10th day of pregnancy, for one hour in
soundproof box with an intensity 65 db. On the 20th day of pregnancy,The Rattus norvegicus offsprings
were born by sectio and selected three with the heaviest, medium and lightest of each mothers to sacrificed
their brains were decapitated and dissection and counted the number of neuron cells using Hematosicline-
Eosin stainin and analyzed using comparison test, with significancy p<0,05.
Results: There were significant differences from the number of neuron cells of offspring Rattus norvegicus
on cerebrum between groups with p= 0.001 and on cerebellum with p= 0.001.
Conclusion: There are differences the number of neuron cells on cerebrum and cerebellum between
offsprings Rattus norvegicus were not exposed to music and those exposed to music.
