Researchers from the University of Helsinki in Finland have found that choral singing in old age improves the structure of the brain's white matter, which is responsible for communication between its different regions. The results of the study are published in Human Brain Mapping (HBM). The study involved 95 healthy adult volunteers between the ages of 21 and 88. The participants were divided into three age categories. The first included young adults (20-39 years old), the second included middle-aged people (40-59 years old), and the third included the elderly (60 years old and older). The scientists studied the relationship between the duration and frequency of choral singing lessons and the structural integrity of the brain's white and gray matter. The results showed significant improvements in white matter connectivity, especially in the corpus callosum, which connects the two hemispheres. These changes were seen in all age groups, but the greatest effects were seen in older participants. In addition, improvements in the white matter vault, which is important for memory, were seen exclusively among the elderly. The researchers noted that choral singing can be an effective way to maintain brain health in the elderly. This activity develops both musical and social skills, making it an affordable and effective way to protect cognitive function and memory from degradation.
