The notion that the brain is able to change in response to stimulation, an ability known as “neuroplasticity,” is now so widely accepted it can be called fact. iLs programs are based on this principle, providing gentle and specific stimulation in order to activate the neural pathways used in the processing of sensory information. This is essentially a type of training: neuronal connections in these pathways are strengthened and new connections are established through repeated sessions of multi-sensory input. iLs programs are customized, i.e. individualized for each person’s therapeutic goals, and they gradually become more complex and challenging as they progress.
iLs programs include classical music that has been acoustically modified to provide enhanced or filtered signals in certain frequencies, as specific frequencies are believed to be correlated to certain brain functions. The music is loaded on an iPod paired with special headphones which deliver it through both air and bone conduction (a low frequency vibration that is conducted by bone to the cochlea and vestibular system). Simultaneous to the auditory component, the user engages in visual, vestibular and motor exercises which maximize the interaction of the systems outlined below.
