This study investigated two questions. One is: To what degree is sentence processing beyond single words independent of the input modality (speech vs. reading)? The second question is: Which parts of the network recruited by both modalities is sensitive to syntactic complexity? These questions were investigated by having more than 200 participants read or listen to well-formed sentences or series of unconnected words. A largely left-hemisphere frontotemporoparietal network was found to be supramodal in nature, i.e., independent of input modality. In addition, the left inferior frontal gyrus (LIFG) and the left posterior middle temporal gyrus (LpMTG) were most clearly associated with left-branching complexity. The left anterior temporal lobe showed the greatest sensitivity to sentences that differed in right-branching complexity. Moreover, activity in LIFG and LpMTG increased from sentence onset to end, in parallel with an increase of the left-branching complexity. While LIFG, bilateral anterior temporal lobe, posterior MTG, and left inferior parietal lobe all contribute to the supramodal unification processes, the results suggest that these regions differ in their respective contributions to syntactic complexity related processing. The consequences of these findings for neurobiological models of language processing are discussed.

Naturalistic reading of multi-page texts elicits spatially extended modulation of oscillatory activity in the right hemisphere.

The study of the cortical basis of reading has greatly benefited from the use of naturalistic paradigms that permit eye movements. However, due to the short stimulus lengths used in most naturalistic reading studies, it remains unclear how reading of texts comprising more than isolated sentences modulates cortical processing. To address this question, we used magnetoencephalography to study the spatiospectral distribution of oscillatory activity during naturalistic reading of multi-page texts.

Understanding how children acquire syntactic structures from a limited set of grammatical rules and use them creatively to convey meaning has been a longstanding interest for scientific communities. Previous studies on syntactic development have revealed its close correlation with the development of vocabulary and working memory. Our study sought to elucidate how the relations between syntactic processing, word processing, and working memory were instantiated in the brain, and how earlier neural patterns might predict language abilities one year later.

is a dimorphic fungus that specifically infects , causing stem swelling and the formation of an edible fleshy stem known as jiaobai. The pathogenicity of is closely associated with the development of jiaobai and phenotypic differentiation. Msb2 acts as a key upstream sensor in the MAPK (mitogen-activated protein kinase) signaling pathway, playing critical roles in fungal hyphal growth, osmotic regulation, maintenance of cell wall integrity, temperature adaptation, and pathogenicity.

When we encounter an unfamiliar word in a sentence, word order can be used to determine the grammatical category to which that word belongs and clarify ambiguity. However, it is unclear whether a similar categorization effect occurs in nonlinguistic contexts. We created three perceptually distinct categories of shape stimuli-rounded (A); squared (B); pointed (C).

This study investigates the cognitive and neural mechanisms involved in the linearization of events during language production, focusing on the processing of temporal conjunctions "before" and "after." While natural language typically presents events in chronological order, non-chronological sequences, as required by "before" sentences, impose additional cognitive demands. Using an adapted network task, we recorded event-related potentials (ERPs) in 24 healthy German speaking participants to examine the brain activity associated with these demands.
