Insights
Music training in children enhances brain activity and motor skills. Children with music education showed improved gamma-band frequency, balance, temporal orientation, and overall motor quotient compared to those without music training.
Area of Science:
- Neuroscience
- Child Development
- Motor Learning
Background:
- Music training's impact on cognitive and motor functions is an area of ongoing research.
- Understanding how music influences brain development in children is crucial for educational and therapeutic interventions.
Purpose of the Study:
- To investigate the relationship between music training and gamma-band frequency in children.
- To compare the motor performance, including balance and coordination, of children with and without music training.
Main Methods:
- A cross-sectional study involving 31 children aged 6-11, divided into a music group (MG) and a no-music group (NMG).
- Electroencephalography (EEG) was used to measure gamma-band frequency.
- Motor skills were assessed using the Movement Assessment Battery for Children and a Brazilian motor development scale.
Main Results:
- Significant differences were observed in frontal gamma-band peak and median frequencies between the groups.
- The music group demonstrated superior performance in static and dynamic balance, temporal orientation, and general motor quotient (GMQ).
Conclusions:
- Music training is associated with enhanced gamma-band activity in the frontal brain regions of children.
- Children with music training exhibit improved motor skills, particularly in balance and temporal processing, alongside a higher overall motor quotient.
Abstract:
Background: The aim of this study was to analyze the gamma-band frequency and motor performance of children with and without music training.Methods: This cross-sectional study included 31 right-handed children, 6-11 years old, who were allocated to two groups: 1) the music group (MG), including children who attended preschool and musical training (n = 16), and 2) the no-music group (NMG), including children who attended preschool but received no additional music training (n = 15). The outcomes were gamma-band frequency measured by electroencephalography, manual dexterity, aim-and-catch, and static and dynamic balance abilities measured by the Movement Assessment Battery for Children, and fine motor skills, overall motor skills, balance, corporal body scheme, spatial organization, temporal orientation, and general motor quotient (GMQ) by a Brazilian scale for motor development.Results: There 1was a significant difference between groups in the peak frequency (p = 0.0195) and median frequency (p = 0.0070) in the F3-F4 regions. Static and dynamic balance (p = 0.03), temporal orientation (p < 0.01), and GMQ (p < 0.03) were higher in MG than in NMG.Conclusion: The musically trained children had increased gamma-peak frequency in the frontal region and greater temporal orientation, balance, and the overall motor quotient.
