This study identifies structural brain differences in frontotemporal and cingulate regions in individuals with congenital aphantasia, suggesting altered higher-order systems may underlie the absence of conscious imagery.

This study shows early sensory deprivation causes localized reorganization near deprived primary sensory areas while preserving the overall cortical hierarchy.

The paper identifies category-preferring patches in the human orbitofrontal cortex using fMRI, showing similar organization and function to the ventral occipitotemporal cortex.

This study uses 7T fMRI to compare neural activity during visual mental imagery and perception in typical imagers and aphantasic individuals, revealing differences in brain connectivity.

This study investigates brain regions involved in cued speech perception in deaf and hearing users, identifying differences in neural activation patterns between experts and novices.

This study shows Drosophila fruit flies spontaneously prefer larger numerical quantities and identifies a neuronal substrate for numerical cognition.

This study uses 7T fMRI to investigate whether bilingual readers have distinct cortical patches for different languages, finding overlapping but specialized regions for English-French and additional patches for English-Chinese.

The paper studies ticker-tape synesthesia (TTS) using fMRI to show that it involves top-down processing of speech into visualized letters, similar to reading, and identifies brain regions involved in this process.

The paper simulates the emergence of the visual word form area by training a convolutional neural network to recognize written words, showing it can replicate key properties of the VWFA.

This study identifies distinct brain networks associated with color naming and categorization using fMRI and behavioral data.

This study investigates whether the visual cortex of early blind individuals codes for word meaning by comparing neuronal activity during a semantic decision task using MEG between blind and sighted participants.

The paper shows that early blind individuals have visual cortex activation during cognitive tasks, which integrates into specific brain networks with distinct functional roles.
