Sever motor and intellectual disabilities (SMID) patients can't express their feelings with languages. That's why it is important to measure and analyze their brain activity. In this study, we tried to investigate the brain response to hearing subject's own name of healthy people and one patient with SMID by analyzing EEG. The results of time frequency analysis showed the inter trial coherence of a patient with SMID at theta oscillation was higher in response to SON specifically. On the other hand, that of healthy subjects was not so different with that in response to control condition. These results might reflect of the difference of lexical semantic process between the patient and healthy subjects.

We suggest that alpha and beta power differences reflect different cognitive functions and that the SON response reveals more than one process. Beta powers may reflect the intellectual disability of cognitive function in response to self-relevant stimuli, especially in patients with cerebral hemorrhage. Meanwhile, alpha powers did not differ from those of the healthy controls, suggesting that the patients perhaps paid attention to their own names.
