The entire brain, more or less, is at work: ‘Language regions’ are artefacts of averaging

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2023, Volume and Issue: unknown

Published: Sept. 3, 2023

Abstract Models of the neurobiology language suggest that a small number anatomically fixed brain regions are responsible for functioning. This observation derives from centuries examining injury causing aphasia and is supported by decades neuroimaging studies. The latter rely on thresholded measures central tendency applied to activity patterns resulting heterogeneous stimuli. We hypothesised these methods obscure whole distribution supporting language. Specifically, cortical ‘language regions’ corresponding network’ consist input connectivity hubs. primarily coordinate peripheral whose variable, making them likely be averaged out following thresholding. tested hypotheses in two studies using meta-analyses functional magnetic resonance imaging during film watching. Both converged averaging over words localised historically associated with but distributed throughout most when not sensorimotor properties those words. word composed highly data shows hubs fixed. Rather, they spatiotemporally dynamic, connections 44% at any moment, only appear aggregate time. Results an artefact indiscriminately across representations linguistic processes. mostly dynamic coordinating whole-brain distributions networks processing complexities real-world use, explaining why damage results aphasia.

A reconceptualization of sentence production in post-stroke agrammatic aphasia: the Synergistic Processing Bottleneck model

Published: Sept. 15, 2023

The language production deficit in post-stroke agrammatic aphasia (PSA-G) tends to result from lesions the left inferior frontal gyrus (LIFG) and is characterized by a triad of symptoms: fragmented sentences, errors functional morphology, dearth verbs. Despite decades research, mechanisms underlying patterns PSA-G have been difficult characterize. Two major impediments progress may view that it purely morphosyntactic disorder (sometimes overzealous) application linguistic theory without interceding psycholinguistic evidence. In this paper, empirical evidence examined present an integrated portrait evaluate assumption syntax-specific syndrome. light extant evidence, proposed results combination morphosyntactic, phonomotor, processing capacity limitations cause cumulative bottleneck at point articulatory planning. This Synergistic Processing Bottleneck model presents testable framework for future research. paper ends with recommendations research on PSA-G.

Disentangling the neural correlates of semantic and domain-general control: The roles of stimulus domain and task process

Imaging Neuroscience, Journal Year: 2024, Volume and Issue: 2, P. 1 - 21

Published: Jan. 25, 2024

Abstract Control processes are critical for the context-appropriate use of meaningful stimuli. Similar definitions have been adopted in two distinct literatures focusing on identifying neural correlates “semantic control” and executive control across domains (the “multiple demand network”). Surprisingly, despite their proposed functions varying only relation to domain-specificity, these networks appear differ anatomically. However, prior comparisons confounded by variations task design. To what extent might requirements drive differences activation patterns that typically attributed stimulus domain? Here, first time, we functional MRI disentangle effects process domain during cognitively demanding tasks. Participants performed an odd-one-out requiring rule-switching, inhibition selection processes, n-back working memory task, each with semantic non-semantic stimuli, a factorial Both affected regions activated, indicating is indeed key factor confounding studies. core (left inferior frontal gyrus, left posterior temporal cortex) also showed preference stimuli even matched while more peripheral regions, overlapping multiple network (dorsomedial prefrontal cortex, right gyrus), little or stimulus. Conversely, most were preferentially engaged These results highlight mutual importance driving variation region engagement, both between networks.

Revisiting the relation between syntax, action, and left BA44

Among the many lines of research that have been exploring how embodiment contributes to cognition, one focuses on neural substrates language may be shared, or at least closely coupled, with those action. This paper revisits a particular proposal has received considerable attention—namely, forms hierarchical sequencing characterize both linguistic syntax and goal-directed action are underpinned partly by common mechanisms in left Brodmann area (BA) 44, cortical region is not only classically regarded as part Broca’s area, but also core component human Mirror Neuron System. First, recent multi-participant, multi-round debate about this summarized together some other relevant findings. review reveals while supported variety theoretical arguments empirical results, it still faces several challenges. Next, narrower application discussed, specifically involving basic word order subject (S), object (O), verb (V) simple transitive clauses.

The Neural Basis of Tonal Processing in Music: An ALE Meta-Analysis

Music & Science, Journal Year: 2022, Volume and Issue: 5

Music is used as an important medium for communication in human societies, often times to enhance the emotional meaning of narrative scenarios and ritual events. has a number domain-specific tonal devices doing this, spanning from scale structure harmonic progressions beyond. In order explore neural basis processing music, we carried out activation likelihood estimation (ALE) meta-analysis 20 published functional magnetic resonance imaging studies cognition, with emphasis on harmony processing. The most concordant areas across these occurred at junction inferior frontal gyrus, anterior insula, orbitofrontal cortex Brodmann 47 13 right hemisphere. This region associated not only emotion general, but conveyance affective meanings during processes, including speech prosody music.

The evolution of musicality and cross-domain co-evolutionary interactions

The evolution of human musicality has often been linked to the faculty language since development musical and linguistic abilities seems share a common phase in their ontogenesis. Apart from that, both singing speaking are, on one hand, universal forms vocal expression and, other consist culturally specific elements. Such probable co-occurrence predisposition speak sing, with cultural variability these communication, prompted researchers indicate gene–culture co-evolution as mechanism responsible for emergence language. However, most evolutionary scenarios proposed so far, paths music followed independently after divergence precursor. This article, based observations contemporary interactions between music, presents different view which language-like proto-communication interacted leading repurposing some neural mechanisms. In this process, Baldwinian interplay plasticity canalization that shaped our musicality. premises support presence cross-domain co-evolutionary communicative niche Homo sapiens are indicated.
