Topic: sensory information processing

The mammalian Prefrontal Cortex (PFC) has been suggested to modulate sensory information processing across multiple cortical regions via long-range axonal projections. These axonal projections arise from discrete PFC subregions with unique brain-wide connectivity and functional repertoires, which may provide the architecture for modular feedback intended to shape sensory processing. Here, we used axonal tracing, axonal and somatic 2-photon calcium imaging, and chemogenetic manipulations in mice to delineate how projections from the Anterior Cingulate Cortex (ACA) and ventrolateral Orbitofronta

Atypical sensory processing affects approximately 90% of individuals with autism spectrum disorder (ASD) and has been recently considered a core ASD symptom. In accordance with neurophysiological findings in human subjects, preclinical studies have found altered activity of primary sensory neocortices and sensory association areas following sensory stimuli and perceptual paradigms in several genetic mouse models of ASD. Attention deficits are a common comorbidity of autism and may impact other symptoms. Indeed, recent research suggests that alterations in attention and sensory processing are i

EEG power measurements have shown correlations with human language abilities, though the results have varied. Alpha power, believed to be modulated by thalamo-cortical networks, reflects sensory information processing. Additionally, alpha power has been more distinctly associated with language abilities compared to other EEG frequencies. This could be due to different degrees of reliability across frequency bands. The aim of this study was to identify the most reliable power measures and investigate their relation to language abilities. A group of children (N = 37) and adults (N = 90) particip
