Abstract Recent work suggests that the individual alpha peak frequency (IAPF) reflects temporal resolution of visual processing: individuals with higher IAPF can segregate stimuli at shorter intervals compared to those lower IAPF. However, this evidence mainly comes from studies focusing on short intervals, stimulus onset asynchronies (SOA) rarely extending beyond a single cycle (e.g., ~100 ms). Here, we investigated relationship between and performance in backward masking (VBM), which allowed us test effects for longer SOAs than an cycle. A group healthy controls (N = 79) schizophrenia patients 121), who generally exhibit IAPF, were tested conditions Vernier shown alone, followed by mask two (30 150 ms), or only mask. Our results show predict VBM all Vernier. Furthermore, both control groups, showed reduced effects, even when SOA ms exceeded These findings challenge notion is exclusively related processing within We discuss alternative mechanisms determines performance.

ABSTRACTBackground: Complex childhood trauma (CCT), characterized by repeated and prolonged exposure to adverse experiences, disrupts cognitive, emotional, neural development. Adolescence, a critical developmental period, is particularly vulnerable these effects, with CCT increasing the risk of psychopathologies, including post-traumatic stress disorder (PTSD). Despite this, neurophysiological underpinnings trauma-related deficits in cognitive control remain insufficiently explored, developing brains children adolescents. This study aimed investigate markers adolescents using event-related potential (ERP) components propose an electrophysiological phenotype associated CCT, as vulnerability for PTSD.Methods: Twenty 40 age- gender-matched healthy controls performed cued GO/NOGO task. ERP - contingent negative variation (CNV), NoGo-N2, NoGo-P3 were analysed alongside behavioural measures such omission commission errors reaction time, preregistered protocol. Statistical analysis included Mann-Whitney tests cluster-based permutation comparisons.Results: Adolescents showed significant impairments both proactive (reduced CNV amplitudes) reactive (diminished NoGo-N2 mechanisms. Behaviourally, group exhibited higher shorter times than controls. Exploratory revealed reduced amplitudes visual negativity (VN) component, suggesting disruptions predictive processing. Latent component identified diagnostic utility, linking key circuits processing.Conclusion: Study findings highlight mechanisms disrupted processing emphasizing importance addressing during adolescence. Given that factor PTSD, provides insights into shared neurobiological pathways, supporting development targeted interventions. like CNV, NoGo-P3, VN show promise improving precision monitoring therapeutic outcomes trauma-exposed youth.

Abstract For decades, the intriguing connection between human alpha rhythm (an 8- to 13-Hz oscillation maximal over posterior cortex) and temporal processes in perception has furnished a rich landscape of proposals. The past decade, however, seen surge interest topic, bringing new theoretical, analytic, methodological developments alongside fresh controversies. This Special Focus on alpha-band dynamics processing provides an up-to-date snapshot playing field, with contributions from leading researchers field spanning original perspectives, evidence, comprehensive reviews meta-analyses, as well discussion ongoing controversies paths forward. We hope that perspectives captured here will help catalyze future research shape pathways toward theoretically grounded mechanistic account link properties perception.

Abstract The papers collected in this Special Focus, prompted by S. Buergers and U. Noppeney [The role of alpha oscillations temporal binding within across the senses. Nature Human Behaviour, 6, 732–742, 2022], have raised several interesting ideas, arguments, empirical results relating to resolution hypothesis. Here we briefly respond these, process emphasize four challenges for future research: defining scope limitation hypothesis; developing experimental paradigms study designs that rigorously test its tenets; decomposing scalp-level signal isolating underlying neural circuits; bringing uniformity current diversity analysis statistical methods. Addressing these will facilitate progression from merely correlating frequency with various perceptual phenomena establishing whether (if so) how influences sensory integration segregation.

Study Design We implemented a causal inference network reproduce responses who scored low schizotypy simulated double flash task. Next, we explored effects Excitation/Inhibition imbalance, feedback weights, synaptic density on visual illusory network. Results Using quantitative fitting empirical data, found that increase recurrent excitation or cross-modal connectivity enlarges window increases overall proneness experience illusion, matching scoring schizotypy.
