EXCESSIVE INHIBITORY SYNAPTIC STRENGTHS - A NEURONAL PROPERTY THEORY OF AUTISM



It is shown that excessive inhibitory synaptic strengths will cause sensory response characteristics often found in autistic individuals. From the theory of self-organizing maps with Hebbian learning, a mathematical model of cortical areas, it furthermore follows that excessive inhibitory synaptic strengths will impair the development of cortical maps, necessary for feature recognition and efficient information processing and storage of salient information in memory. This can explain Hermelin's experimental finding that autistic individuals perform less recoding from sensory input to more abstract codes. It is also argued to be in agreement with Frith's theory of lack of drive for central coherence in autistic individuals.
