AI Article Synopsis

  • Semantic access disorders are recognized conditions, but their exact cognitive and anatomical causes are still under discussion.
  • A case study of a patient who became aphasic after surgery for a left frontal glioma is presented.
  • The patient's impairment, characterized by refractory semantic access dysphasia, suggests a strong link between damage to the left prefrontal cortices and issues with retrieving and selecting verbal information.

Article Abstract

The existence of semantic access disorders is now well established, however the precise cognitive and anatomical underpinnings are still debated. Here we describe the case of a patient that became aphasic after the resection of a left frontal glioma. Detailed lesion reconstruction indicates that the lesion was mostly restricted to the left dorsal and ventral prefrontal cortices and the underlying white matter, but sparing temporal lobes. Critically, the patient showed all the signs of refractory semantic access dysphasia, supporting the association between this syndrome and damage to left prefrontal areas likely to subserve retrieval and selection mechanisms for verbal material.

Background: Dementia is a progressive and terminal illness. Symptoms are present for people with dementia across all stages, leading to poor quality of life and considerable carer burden. In acute and community care services, no holistic, person-centred outcome tools are available for nurses and informal caregivers to measure symptoms and needs from the person`s with dementia point of view.

Purpose: Children with hearing loss (CHL) who use hearing devices (cochlear implants or hearing aids) and communicate orally have trouble comprehending sentences with noncanonical order. This study explores sentence comprehension strategies in Spanish-speaking CHL, focusing on their ability to integrate morphosyntactic cues (word order, morphological case marking) with verbs differing in their syntax-to-semantics configuration.

Method: Fifty-eight Spanish-speaking CHL and 58 children with typical hearing (CTH) with a hearing age of 3;5-7;8 (years;months; i.

Background And Purpose: Despite comprehensive evidence that supports the utility of aphasia therapy in persons with chronic (≥6 months) stroke-induced aphasia, the amount of therapy provided to patients in the United States is typically far less than what is likely necessary to maximize recovery. Two potential contributors to this discrepancy are limited access to rehabilitation services due to the availability of providers and logistical difficulties with transportation. One way to increase access to aphasia therapy is to rely on telerehabilitation.

Protocol to profile snATAC-seq datasets and motif enrichment analysis during zebrafish early embryogenesis.

The scarcity of zebrafish-specific motif databases presents a challenge to the analysis of transcription factor (TF) motif within zebrafish single-cell assay for transposase-accessible chromatin using sequencing (scATAC-seq) data, thus hindering the identification of regulatory elements throughout zebrafish embryonic development. Here, we provide a protocol to analyze single-nucleus chromatin accessibility dataset during zebrafish early embryogenesis. We describe steps for fragment file retrieval, sample integration, quality control, Latent Semantic Indexing (LSI) clustering, and peak calling via ArchR.

Article Synopsis
  • * Studies show that coherence, or the logical connection between ideas, is vital for readers with limited background knowledge, as these readers struggle to infer implicit connections.
  • * Research finds a strong link between reader comprehension and automated measures of text coherence, indicating that improving text comprehensibility enhances reader understanding, especially in biomedical contexts.
