Interhemispheric asymmetry in EEG photic driving coherence in childhood autism

Epilepsy and Autism

“…As in the imaging reports, the resulting evidence is conflicting and inconsistent. Twenty-one studies in the last decade have been published; 11 evaluated resting state (Murias et al 2007;Coben et al 2008;Barttfeld et al 2011;Bosl et al 2011;Duffy and Als 2012;Mathewson et al 2012;Sheikhani et al 2012;Leveille and Hannagan 2013;Peters et al 2013;Machado et al 2015), eight were task related (Isler et al 2010;Lazarev et al 2010;Catarino et al 2013;Garcia Dominguez et al 2013;Carson et al 2014;Orekhova et al 2014;Righi et al 2014;Lazarev et al 2015;Machado et al 2015); one obtained during non-rapid eye movement (NREM) sleep (Lazar et al 2010) and one obtained during rapid eye movement (REM) sleep (Leveille et al 2010). It is not possible to directly compare these studies as the acquisition paradigm, the age of the subjects, Figure 3.…”

Improving Pragmatics in Nonverbal Children with Autism Using Melodic Based Communication Therapy

“…Appropriate interventions should target social language as well as receptive/expressive language and imitative abilities. Research supports right hemispherical strengths in children with autism as well as improvement in corpus callosum function with exposure to music [18][19][20][21][22][23][24][25][26]. Therefore, the implementation of therapy techniques employing the use of melody and rhythm, right hemisphere tasks, may be helpful for this population.…”

Diagnosing Autism Spectrum Disorders Based on EEG Analysis: a Survey

“…It was found that, unlike the spectral characteristics indicating deficit in the photic driving reactivity in the right hemisphere, the groups were different in terms of the number of HCC only in the left hemisphere. Also, there was increased prevalence of the frequency in the left hemisphere [59]. In the same year, Sudirman et al [60] collected EEGs from six normal children, two autism-suffering children, and eight Down syndrome children under the actions of two stimuli consisting of alternating checkerboard and ripple checkerboard.…”

“…Lazarev et al [59] examined photic driving coherence during intermittent photic stimulation in 14 autistic boys (6-14 years old, with IQ 91.4 ± 22.8) and 19 normally developing boys who were subjected to stimulation of 12 fixed frequencies (3-27 sec -1 ). The number of high coherent connections (HCCs) (coherence > 0.6-0.8) was estimated among seven leads in each hemisphere.…”
