در برخی موارد پردازش­های ذهنی در درک شنیداری زبان گفتار با دشواری روبه­روست. به نظر می­رسد فعال­سازی صورت نوشتاری کلمات در ذهن می­تواند در چنین شرایطی درک را تسهیل نماید. در این مقاله، با توجه به اینکه یافته­های پژوهشی نشان می­دهند که پردازش و دسترسی به کلمات هم­آوای ناهم­نویسه از دیگر کلمات دشوارتر است، در پی شناسایی نقش خط نوشتار و صورت نوشتاری واژگان در پردازش و درک این نوع کلمات به هنگام فر...

According to a simple anatomical and functional model of word reading, letters displayed in one hemifield are first analysed through a cascade of contralateral retinotopic areas, which compute increasingly abstract representations. Eventually, an invariant representation of letter identities is created in the visual word form area (VWFA), reproducibly located within the left occipito-temporal s...

Seeing words involves the activity of neural circuitry within a small region in human ventral temporal cortex known as the visual word form area (VWFA). It is widely asserted that VWFA responses, which are essential for skilled reading, do not depend on the visual field position of the writing (position invariant). Such position invariance supports the hypothesis that the VWFA analyzes word for...

CRIT (complement C2 receptor inhibitor trispanning) is a newly described transmembrane molecule that is capable of binding C2 via its first extracellular domain (ed1). CRIT competes with C4b for the binding of C2. Previous experiments have suggested that a major binding site for C2 is located on short, almost identical peptide sequences of CRIT-ed1 and the beta-chain of C4. The C2 domains invol...

Previous studies have identified the critical role of the left fusiform cortex in visual word form processing, learning, and memory. However, this so-called visual word form area's (VWFA) other functions are not clear. In this study, we used fMRI and the subsequent memory paradigm to examine whether the putative VWFA was involved in the processing and successful memory encoding of faces as well...

Activation of the left midfusiform gyrus in response to reading words and pseudowords is such a reliable finding in functional imaging that this region has been called "the visual word form area" (VWFA). However, this label has recently been challenged, because activation in VWFA is also observed in other lexical tasks. We evaluated whether VWFA is necessary, sufficient, or specialized for read...

Learning to read causes the development of a letter- and word-selective region known as the visual word form area (VWFA) within the human ventral visual object stream. Why does a reading-selective region develop at this anatomical location? According to one hypothesis, the VWFA develops at the nexus of visual inputs from retinotopic cortices and linguistic input from the frontotemporal language...

Reading plays a key role in education and communication in modern society. Learning to read establishes the connections between the visual word form area (VWFA) and language areas responsible for speech processing. Using resting-state functional connectivity (RSFC) and Granger Causality Analysis (GCA) methods, the current developmental study aimed to identify the difference in the relationship ...

The visual word form area (VWFA) is a region of the cortex located in the left fusiform gyrus, that appears to be a waystation in the reading pathway. The discovery of the VWFA occurred in the late twentieth century with the advancement of functional magnetic resonance imaging (fMRI). Since then, there has been an increasing number of neuroimaging studies to understand the VWFA, and there are d...
