The approach is based upon certain irrefutable facts concerning brain function, which are applied to the treatment of children's developmental difficulties. The first of these is brain plasticity. It is now unchallengeable that the brain is capable of changing its structure and functioning in response to the environment in which it finds itself. We can see this in the growth of new synaptic connections and the pruning of inefficient ones.
The question then is, what do we mean by 'environment' and how can we manipulate this variable in order to encourage the brain to respond in the way we wish?
The brain takes in information from the sensory environment, through the eyes, ears, nose, mouth and skin. Specific areas are responsible for processing this information and then re-routing it to the appropriate part of the cortex for further attention, evaluation and action. When the brain is working as it should, then all of this is achieved with the maximum efficiency, without you or I ever noticing what is occurring. However, as we are all aware, the brain does not always work as it should! For many children, this sensory information either does not reach the relevant part of cortex at all, or if it does, the signal has been weakened sufficiently so that processing becomes almost impossible. For other children, the sensory stimuli reaches the cortex for processing in a distorted manner and the child is overwhelmed by the world it perceives.
