There have also PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/23737661 been investigations in to the added benefits of mu neurofeedback education, which have argued that this may perhaps represent a prospective remedy for autism inside the future [0307]. At present, mu suppression findings with autistic groups have been decidedly varied, with half with the research concluding that mu suppression during observations of actions is deficient in autism (suggesting abnormal or impaired mirror neuron systems), and half getting mu suppression comparable with controls. There have already been some attempts to clarify these varied findings by appealing to more aspects; for instance, Oberman et al. [60] found that mu suppression in their autistic sample was modulated by familiarity together with the model (arguably, one could hyperlink the findings of Gutsell et al. [89] relating mu suppression to prejudice to these of Oberman et al. [60], as presumably ingroup members are much more familiar with their very own group). Having said that, one of the most current paper to investigate mu suppression abnormalities in autism points towards abnormalities in the mu frequency band, but suggests that these abnormalities arise from locations not normally associated with mu, but rather with alpha. When only examining the central electrodes, for example is typically accomplished in mu suppression experiments, Dumas et al. [39] replicated preceding reports of reduced suppression to actions with objects. Having said that, when thinking of variations across the whole scalp, Dumas et al. [39] found abnormalities within the alpha frequency band in the frontal and occipital regions in their participants with ASD. Indeed, there’s evidence that the broader alpha band, as opposed to mu, is abnormal in ASD; Mathewson et al. [08] noted in their study that participants inside the ASD group had greater alpha power in an eyesopen condition, and that they showed smaller occipital alpha suppression when comparing eyesopen to eyesclosed circumstances than typical controls. Lowered suppression in the alpha band is for that reason not particular to mu regions or biological stimuli. Moreover, it can be plausible that consideration can be various between ASD and typical participants when viewing biological motion, and that this could be reflected in differences in alpha activity. Consideration to social stimuli has been shown to become abnormal in ASD (see [09] and [0], for examples and of those troubles in both auditory and visual domains, respectively).
