Music, the universal language of mood, emotion and desire, connects with us through a wide variety of neural systems. Researchers have discovered evidence that music stimulates specific regions of the brain responsible for memory, language and motor control. They have located specific areas of mental activity linked to the emotional responses elicited by music. Now new research conclusions have identified how the affect of music could replicate the effects of hormone replacement therapy in the prevention of Alzheimer's disease and dementia.
Music affects levels of such steroids as cortisone, testosterone and estrogen, and it is believed that music also affects the receptor genes related to these substances and related proteins. Unlike supplementing the brain through hormone replacement therapy which can have side effects, music is natural, and its existence is universal and mundane. If music can be used in medical care, the application of such a safe and inexpensive therapeutic option is limitless.
Studies as far back as 1990 found that the brain responds to harmony. Using a PET scanner to monitor changes in neural activity, neuroscientists at McGill University discovered that the part of the brain activated by music is dependent on whether or not the music is pleasant or dissonant.
This new research is beginning to help those involved in cognitive rehabilitation. Music is now used with patients with stroke, schizophrenia, Huntington's, Alzheimer's and traumatic brain injury among others. Read the entire article.
