The Johansen-IAS therapy is developed by dr. Kjeld V. Johansen, director of the Baltic Dyslexia Research Laboratory in Gudhjem, Bornholm, Denmark. By listening to specially recorded music CDs nerve pathways to and within the language centre in the brain are stimulated. It specially stimulates those nerve pathways which connect the right ear with the left hemisphere. From this part of the brain incoming information is transported to the deeper processing areas. Various brain scans show that this kind of stimulation can increase numbers of connectors in the form of dendrites and synapses. Connections in other language centres are therefore speeded up more efficient. This results in a more efficient language processing. Concentration and understanding improves, because of a faster processing of information.
