Music-making creates clear changes in the human brain
“As many as three in ten children with autism are nonverbal. Yet many children with autism have superior auditory skills and a particular attraction to music. Based on these observations, I and my colleagues have been using forms of music-making that encourage vocalization as a pathway to developing language.
We call our therapy Auditory-Motor Mapping Training (AMMT), and our approach is built on two findings.
First research has shown that music-making creates clear changes in the human brain. In particular we know that it engages and strengthens connections between the auditory and motor regions and improves mapping of sounds to actions. Second, here at our Music and Neuroimaging Lab, we have successfully used a form of singing (i.e., Melodic Intonation Therapy) to help stroke patients regain speech lost after a stroke (aphasia). In essence, our therapies involve having the patient sing words and phrases while using a coordinated movement of the hand not affected by the stroke. This helps their brains map sounds to actions.
In recent years, we’ve adapted our music-motor therapy for stroke victims in ways that allow us to use it with children who have autism and little or no speech. In simplified terms: Our team members sing words and phrases with social connotations (for example, “more please,” “mommy,” “all done”) to the children and with the children, while showing them pictures of the action, person or object. At the same time, we guide each child’s hand to play two drum pads tuned to different pitches.
We believe that intensive, repetitive training—pairing sound with actions–can engage and strengthen the brain pathways needed to speak. In our recently published “proof of concept” study, each participant received 40 treatment sessions, conducted 5 days per week over an 8 week period, with each session lasting 45 minutes. Further analysis revealed that the therapy’s benefits probably occur in the first 25 sessions.”
