The proposed project will be first performed on individuals with HF-ASD with their expected heterogeneity and healthy control (HC) subjects in order to explore the pain processing and modulation mechanisms underlying the pain sensitivity profile of adults with HF-ASD. Secondly, we will focus on individuals with ASD and HC, without ASR (ASD-nonASR, HC-nonASR) and with SHR (ASD-SHR, HC-SHR). This 2X2 factorial design will enable us to determine whether the feature of SHR in individuals with HF-ASD contributes to pain sensitivity. This research project will comprise of two sessions. Session I will include the following tests ADOS-2 for ASD diagnosing (only for individuals with ASD), intelligence quotation testing (IQ Wechsler Abbreviated Scale of Intelligence® - Second Edition (WASI®-II)107, serving for inclusion criteria. Session II will include familiarization with the researchers and lab, thermal detection threshold testing for small fiber abnormality identification since detection thresholds in some reports found to be abnormal pain threshold testing, and completion of questionnaires (see section 3.6 for details), psychophysical testing and EEG recordings in the following order: i) rEEG recordings; ii) psychophysical pain assessments; simultaneously with iii) neurophysiological pain assessments with pain EPs recorded. Our research protocol will be approved by the Helsinki Committee of the Rambam Health Care Center and The Chaim Sheba Medical Center.
