The causes for ASD and DLD are many, complex and largely unknown. One specific cause already identified is mutation of a single gene essential for neuronal development. A useful transgenic rat model has been developed with this mutation that exhibits disabilities very reminiscient of children with ASD or DLD. We will use it to demonstrate that the same tests can show the same disruptions to the auditory system between children with ASD/DLD and this rat model. This model can then be used to undertake further exploration of the impact of ASD/DLD on the auditory system and evaluation of possible behavioural and pharmacological interventions.
