TL;DR: The results suggest that ANNs trained using distributed representations provide a better correspondence between cognitive and neural coding, and this framework provides a principled approach for comparing computational models of cognitive function to gain insight into neural representations.

Abstract: Determining how the cognitive components of reading—orthographic, phonological, and semantic representations—are instantiated in the brain has been a long-standing goal of psychology and human cogn...

Correspondence between cognitive and neural representations for phonology, orthography, and semantics in supramarginal compared to angular gyrus
William W. Graves,Jeremy J. Purcell,David Rothlein,Donald J. Bolger,Miriam Rosenberg-Lee,Ryan Staples +5 more
TL;DR: This work re-analyzes a functional magnetic resonance imaging data set of participants reading aloud 465 words to systematically test for correspondence between patterns of neural activation and phonological, orthographic, and semantic representations, and test the hypothesis that within cytoarchitecture-defined subregions of the IPL, phonological representations are primarily associated with the SMG, while semantic representation are primarilyassociated with the AG.

Stimulus repetition and sample size considerations in item-level representational similarity analysis
TL;DR: This study investigates the effects of stimulus repetition and sample size on neural representational dissimilarity matrix (RDM) reliability in fMRI data, finding that repetition suppression affects reliability gains and that increasing participants may be more beneficial than repetition.

Duality of Function: Activation for Meaningless Nonwords and Semantic Codes in the Same Brain Areas.
TL;DR: While areas of the default mode network have been hypothesized to support semantic cognition, this work offers evidence that these areas can respond to both domain-general difficulty effects, and to specific aspects of semantics.
Practices and pitfalls in inferring neural representations.
TL;DR: This paper argues that Stimulus-feature-based encoding models' inferential inferences are not always valid because successful prediction can occur even if the two representational spaces use different, but correlated, representational schemes, and discusses ways to overcome inferential limitations.

Exploring the impact of plasticity-related recovery after brain damage in a connectionist model of single-word reading
TL;DR: The results suggest that the performance patterns of brain-damaged patients can owe as much to the substantial changes in the pattern of connectivity occurring during recovery as to the original premorbid structure.

Conduction aphasia, sensory-motor integration, and phonological short-term memory - An aggregate analysis of lesion and fMRI data

TL;DR: The region of maximal lesion overlap in a sample of 14 patients with conduction aphasia perfectly circumscribes area Spt, as defined in an aggregate fMRI analysis of 105 subjects performing a phonological working memory task.
