“…3 Specifically, the authors suggest that the local and global levels are not hierarchically distinguishable in individuals with ASD, who find it difficult to switch from one level of representation/abstraction to the other (Plaisted et al, 1999). This is consistent with evidence that a fairly rigid trade-off between either local or global processing exists in children and adults with ASD, with individuals performing well on one level or the other but rarely both, whereas TD individuals switch back and forth 2 See Bouvet, Simard-Meilleur, Paignon, Mottron & Donnadieu (2014); K e€ ıta, Guy, Berthiaume, Mottron & Bertone (2014) ;Muth, H€ onekopp & Falter (2014); Olu-Lafe, Liederman & Tager-Flusberg (2014); and Yamasaki, Maekawa, Takahashi, Fujita, Kamio et al (2014), for more recent evidence. 3 Whereas (weak) central coherencelocal-global processingused to be viewed as a continuum (e.g.…”

Both Williams syndrome (WS) and Autism Spectrum Disorder (ASD) have been characterized as preferentially processing local information, whereas in Down syndrome (DS) the reported tendency is to process stimuli globally. We designed a cross-syndrome, cross-task comparison to reveal similarities and differences in local/global processing in these disorders. Our in-depth study compared local/global processing across modalities (auditory-verbal/visuo-spatial) and levels of processing (high/low) in the three syndromes. Despite claims in the literature, participants with ASD or WS failed to show a consistent local processing bias, while those with DS failed to show a reliable global processing bias. Depending on the nature of the stimuli and the task, both local and global processing biases were evident in all three neurodevelopmental disorders. These findings indicate that individuals with neurodevelopmental disorders cannot simply be characterized as local or global processors.

“…P100, component associated with processing of visual stimuli showed no difference between ASD and typically developing group when low contrast achromatic sinusoidal gratings are used as stimuli, which in turn suggests a normal magnocellular (M) pathway in visual system (Yamasaki et al, 2014). Studies have also exhibited increased amplitude and latency in P100 component thus indicating longer time to differentiate target from novel stimuli (Sokhadze et al, 2009).…”

“…P300 is the major component which is associated with higher level attention and memory updating processes. P300 waveform has two components: P3a reflecting involuntary attention to stimuli and P3b associated with active attention to stimuli (Yamasaki et al, 2014). The visual attention pattern is altered in ASD compared with the normal and the two associated ERP components are: MMN and P300.…”

“…The attention network in human brain has been divided into bottom‐up (ventral) attention network and top‐down (dorsal) attention network. ERP based studies were conducted to examine the functioning of these networks using oddball paradigm (Maekawa et al, 2011; Yamasaki et al, 2014). It was noted that the ASD group exhibited reduced P300 amplitude indicating impaired top‐down attention network and no change in MMN response suggesting an intact bottom‐up attention network.…”

Autism Spectrum Disorders (ASD) comprise all pervasive neurodevelopmental diseases marked by deficits in social and communication skills, delayed cognitive development, restricted and repetitive behaviors. The core symptoms begin in early childhood, may continue life-long resulting in poor performance in adult stage. Event-related potential (ERP) is basically a time-locked electroencephalogram signal elicited by various stimuli, related to sensory and cognitive processes. The various ERP based techniques used for the study of ASD are considered in this review. ERP based study offers the advantage of being a non-invasive technique to measure the brain activity precisely. The techniques are categorized into three based on the processing domain: time, frequency and time-frequency. Power spectral density, coherence, phase synchrony, multiscale entropy, modified multiscale entropy, sum of signed differences, synchrostates and variance are some of the measures that have been widely used to study the abnormalities in frequency bands and brain connectivity. Various signal processing techniques such as Fast Fourier Transform, Discrete Fourier Transform, Short-Time Fourier Transform, Principal Component Analysis, Wavelet Transform, Directed Transfer Function etc. have been used to analyze the recorded signals so as to unravel the distinctive event-related potential patterns in individuals with ASD. The review concludes that ERP proves to be an efficient tool in detecting the brain abnormalities and connectivity issues, indicating the heterogeneity of ASD. Many advanced techniques are utilized to decipher the underlying neural circuitry so as to aid in therapeutic interventions for improving the core areas of deficits.

Tackling hypo and hyper sensory processing heterogeneity in autism: From clinical stratification to genetic pathways

et al. 2022

As an integral part of autism spectrum symptoms, sensory processing issues including both hypo and hyper sensory sensitivities. These sensory specificities may result from an excitation/inhibition imbalance with a poorly understood of their level of convergence with genetic alterations in GABA‐ergic and glutamatergic pathways. In our study, we aimed to characterize the hypo/hyper‐sensory profile among autistic individuals. We then explored its link with the burden of deleterious mutations in a subset of individuals with available whole‐genome sequencing data. To characterize the hypo/hyper‐sensory profile, the differential Short Sensory Profile (dSSP) was defined as a normalized and centralized hypo/hypersensitivity ratio from the Short Sensory Profile (SSP). Including 1136 participants (533 autistic individuals, 210 first‐degree relatives, and 267 controls) from two independent study samples (PARIS and LEAP), we observed a statistically significant dSSP mean difference between autistic individuals and controls, driven mostly by a high dSSP variability, with an intermediated profile represented by relatives. Our genetic analysis tended to associate the dSSP and the hyposensitivity with mutations of the GABAergic pathway. The major limitation was the dSSP difficulty to discriminate subjects with a similar quantum of hypo‐ and hyper‐sensory symptoms to those with no such symptoms, resulting both in a similar ratio score of 0. However, the dSSP could be a relevant clinical score, and combined with additional sensory descriptions, genetics and endophenotypic substrates, will improve the exploration of the underlying neurobiological mechanisms of sensory processing differences in autism spectrum.
