PERBEDAAN PENGARUH PAPARAN MUSIK MOZART, BEETHOVEN, DAN CHOPIN SELAMA KEBUNTINGAN TERHADAP KEPADATAN DENDRIT DI CEREBELLUM Rattus norvegicus BARU LAHIR
Abstract
Indonesia is categorized as middle human
development index. One of the causes is the fluent
ignorance of brain growth and development during
1000 days of life period. This period is the best
opportunity to give proper stimulations to increase the
maximal brain growth and development. Exposure to
classical music such as Mozart, Beethoven, and
Chopin music can increase the wave of brain activity.
During pregnancy, Mozart music is proven to increase
the dendritic density. Analyzing the difference of
dendritic density of cerebrum and cerebellum of
newborn baby of Rattus norvegicus that are exposed
to the Mozart, Beethoven, and Chopin music, and that
is not exposed to music during pregnancy. Laboratory
experimental research, posttest-only control group
design. Subjects were female pregnant Rattus
norvegicus, grouped into 4 random groups: 1 control
group and 3 treatments groups; with 6 samples each.
Subjects were super ovulated, and 65 dB intensity of
music was played for an hour at 20.00-21.00 on the
subjects on 10th day of pregnancy. On 20th day of
pregnancy, the mothers were dissected using
caesarean section. 2 heaviest newborn babies of
Rattus norvegicus were taken, and their brain tissues
were taken as samples. The dendritic density of
cerebrum and cerebellum were observed using GolgiCox method of silver impregnation
procedure.Statistical test concluded there were
significant differences of dendritic density of cerebrum
and cerebellum of newborn babies of Rattus
norvegicus among the exposure to Mozart,
Beethoven, and Chopin music, and without the
exposure to music with value of p=0,004 (<0,05) in
cerebrum and p=0,003 (<0,05) in cerebellum. The
dendritic density of cerebrum and cerebellum of
newborn babies of Rattus norvegicus that were
exposed to Mozart music during pregnancy were
higher than that are exposed to Beethoven and
Chopin music and that were not exposed to music. It
is recommended for the next research to do further
research to prove the dendritic density caused by the
musical stimulation during pregnancy when Rattus
norvegicus grows up.
