Post-stroke outcomes predicted from multivariate lesion-behaviour and lesion network mapping

Mark Bowren et al.

Summary: Predicting chronic post-stroke outcomes is challenging due to individual variability and reliance on clinical heuristics. This study explores the use of lesion-behaviour mapping and structural and functional lesion networks to improve prediction of 12-month cognitive and motor outcomes in stroke patients. The results show that both methods can significantly predict variance in outcomes, with variations in performance for specific deficits.

A tale of two gradients: differences between the left and right hemispheres predict semantic cognition

Tirso Rene del Jesus Gonzalez Alam et al.

Summary: Decomposing whole-brain functional connectivity patterns revealed a principal gradient separating sensorimotor cortex from heteromodal regions in the default mode network. Left and right hemispheres may have differences in the principal gradient, affecting semantic cognition and visual reasoning.

Machine learning-based multimodal prediction of language outcomes in chronic aphasia

Sigfus Kristinsson et al.

Summary: Recent studies have combined multiple neuroimaging modalities to predict aphasia severity and specific language measures using machine learning approaches. The multimodal prediction model showed the most accurate prediction, indicating that integrating different neuroimaging modalities can more accurately depict the impact of brain damage and intact brain tissue functionality on language function in aphasia.

Knowing what you need to know in advance: The neural processes underpinning flexible semantic retrieval of thematic and taxonomic relations

Meichao Zhang et al.

Summary: The study found that the flexibility in semantic retrieval allows us to focus on relevant features and associations based on the current task or context. Knowing in advance the type of link to retrieve between concepts can lead to greater activation in certain regions of the brain, while a weaker semantic relationship between items can result in a stronger response in overlapping regions.

The neural correlates of semantic control revisited

Multiple dimensions underlying the functional organization of the language network

Victoria J. Hodgson et al.

Summary: Understanding the functional organization of the language network involves distinguishing between semantic and phonological processing, with overlapping but dissociable regions. Regions may also be categorized by control and representation processes, reflecting distinct dimensions within the language network organization. The involvement of multiple-demand network regions beyond the language domain also contributes to the specificity of language regions.

Impaired emotion perception and categorization in semantic aphasia

Nicholas E. Souter et al.

Summary: According to a constructionist model of emotion, conceptual knowledge is essential for emotion perception. Deficits in semantic retrieval can impair emotion perception, leading to difficulties in categorizing emotions and recognizing subtle differences in emotional states. Patients with semantic aphasia, who have difficulty accessing semantic information following left hemisphere stroke, show deficits in emotional perception but can benefit from word anchors and cue conditions to facilitate emotion perception.

Both Default and Multiple-Demand Regions Represent Semantic Goal Information

Xiuyi Wang et al.

Summary: The study utilized a semantic feature-matching task combined with multivoxel pattern decoding to test the role of the default mode network (DMN) and multiple-demand cortex in cognitive flexibility. The results showed that DMN and multiple-demand regions may support the same function instead of strictly competing, as both areas exhibited similar decoding patterns when processing conceptual features related to current task goals.

Evidence for a deep, distributed and dynamic code for animacy in human ventral anterior temporal cortex

Timothy T. Rogers et al.

Summary: The study reconciles two seemingly contradictory views on how the human brain encodes semantic information about objects. It finds that information about the animacy of a stimulus is distributed across ventral temporal cortex in a dynamic code with feature-like elements posteriorly but rapidly changing and nonlinear elements in anterior regions. This suggests that anterior temporal lobes may serve as a deep cross-modal 'hub' in an interactive semantic network, and that tertiary association cortices may adopt dynamic distributed codes difficult to detect with common brain imaging methods.

The default mode network in cognition: a topographical perspective

Jonathan Smallwood et al.

Summary: The default mode network (DMN) consists of widely distributed brain regions in the parietal, temporal, and frontal cortex, showing reduced activity during attention-demanding tasks and increased activity during complex cognition tasks. DMN is located in regions furthest away from sensory and motor systems in the cortex. Leveraging knowledge of the topographic characteristics of DMN can enhance understanding of its contribution to cognition and behavior.

Distinct and common neural coding of semantic and non-semantic control demands

Zhiyao Gao et al.

Summary: The study found that semantic and non-semantic demands led to both similar and distinct neural responses across control-related networks. While the difficulty of both semantic and working memory decisions could be decoded in both the semantic control network and multiple-demand network, there was no shared neural coding of cognitive demands in the semantic control network regions.

A novel stroke lesion network mapping approach: improved accuracy yet still low deficit prediction

Lorenzo Pini et al.

Summary: The new methodology of lesion network mapping in stroke improves the estimation of functional brain network disconnected, but falls short in predicting neurological impairment post-stroke. Despite yielding networks with higher anatomical specificity, the approach does not perform better than the standard method in predicting behavioral deficits.
