abstract = {BackgroundAutism spectrum disorder (ASD) is a
neurodevelopmental disorder characterized by impairments of
social interaction and communication as well as repetitive,
stereotyped behaviour. Previous research indicates that ASD
without intellectual impairment is associated with
underactivity and reduced functional connectivity of the
brain’s mentalizing pathway, to which the right
temporo-parietal junction (rTPJ) serves as an important
entry point and hub. In this study, we aim to utilize
functional magnetic resonance imaging (fMRI) to localize
activation maxima in the rTPJ and other regions involved in
social cognition to generate individualized targets for
neuro-navigated, intermittent theta burst stimulation (iTBS)
in order to modulate brain activity in a region centrally
engaged in social information processing.MethodsIn this
single-blind, randomized, between-subject
neuroimaging-guided brain stimulation study we plan to
recruit 52 participants with prediagnosed ASD and 52
controls without ASD aged between 18 and 65 years.
Participants will be classified into two groups and will
randomly receive one session of either verum- or sham-iTBS.
Effects will be assessed by using well-established
experimental tasks that interrogate social behaviour, but
also use computational modelling to investigate brain
stimulation effects at this level.DiscussionThis study aims
to use personalized, non-invasive brain stimulation to alter
social information processing in adults with and without
high-functioning ASD, which has not been studied before with
a similar protocol or a sample size of this magnitude. By
doing so in combination with behavioural and computational
tasks, this study has the potential to provide new
mechanistic insights into the workings of the social brain.},
