Measurement of brain activity responded by subjects'own name using EEG

Abstract

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.

Towards an electroencephalographic measure of awareness based on the reactivity of oscillatory macrostates to hearing a subject's own name

“…The subject's own name (SON) was found to be a very salient auditory stimulus (Moray, 1959) for probing conscious perception in novelty event-related EEG potential studies (Fischer et al, 2008;Perrin et al, 2006;Schnakers et al, 2008), EEG time-frequency studies (Fellinger et al, 2011;Lechinger et al, 2016;Tamura et al, 2013Tamura et al, , 2016 and in EEG reactivity studies employing prolonged stimulation (Wu et al, 2018). The aim of this study was, therefore, to investigate the DER to repetitive auditory target stimulation by SON (DER SON ) in healthy volunteers and acute post-stroke patients with different degrees of consciousness impairment as measured by the Glasgow Coma Scale (GCS) (Reith et al, 2016;Teasdale & Jennett, 1974).…”
