EEG photic driving: Right-hemisphere reactivity deficit in childhood autism. A pilot study

Individuals with Autistic-Like Traits Show Reduced Lateralization on a Greyscales Task

“…Evidence from pragmatic language measures (Ozonoff and Miller 1996;Siegal et al 1996), functional and structural magnetic resonance imaging (Di Martino et al 2011;Jou et al 2010) and electrophysiological recordings (Lazarev et al 2009;Orekhova et al 2009) suggests that right hemisphere (RH) abnormalities may contribute to the development of these behaviours. Here, we investigate whether high levels of autistic-like traits are also linked to RH-based atypical biases in spatial attention.…”

Diagnosing Autism Spectrum Disorders Based on EEG Analysis: a Survey

“…The report indicated that significant mu suppression in both self and observed hand movements were evident in both groups [36]. In the same year, Lazarev et al [56] investigated the EEG photic driving at various stimulation frequencies (intermittent photic stimulation at 11 fixed frequencies, from 3 to 24 sec -1 , in 14 autistic boys (6-14 years old) and 21 control boys matched in age. The interhemispheric asymmetry in the total number of driving peaks in each group and the difference between autistic and control groups in each hemisphere were evaluated for each frequency band of the four harmonics in the nonvisual areas and the sum of four harmonics in both nonvisual and occipital visual areas.…”

“…The interhemispheric asymmetry in the total number of driving peaks in each group and the difference between autistic and control groups in each hemisphere were evaluated for each frequency band of the four harmonics in the nonvisual areas and the sum of four harmonics in both nonvisual and occipital visual areas. The researchers deduced that boys with autism showed latency abnormalities in the right-side hemisphere during the photic driving reactivity, particularly at the rapid alpha and beta frequencies of stimulation [56].…”

Update on autism: A review of 1300 reports published in 2008

“…Lazarev et al [237] studied photic driving on the EEG, showing, in the group with autism, reduced driving on the right hemisphere, providing evidence for a neurophysiological disturbance within that hemisphere. With 128-channel ERPs, responses to face detection were weaker in the group with autism, suggesting aberrant neurophysiological processing of facial emotion [238].…”
