The paper dissociates neural representations of cognitive maps and graphs in the human brain using fMRI and representational similarity analysis.

The paper shows that eye movements in early blind individuals reflect attentional navigation of the mental number line, suggesting that such movements are driven by internal attention rather than visual experience.

This study uses MEG to investigate how early visual cortex supports lexical and semantic processing in sighted and blind individuals, finding task-specific decoding differences in occipital areas.

The paper investigates how the brain represents time using two complementary reference frames, finding distinct roles for the hippocampus and posterior parietal cortex in memory storage and retrieval.

The paper investigates how the brain accesses stored knowledge by comparing conceptual search to foraging in physical space, finding hippocampal theta power increases and theta-gamma coupling during semantic memory retrieval.

The paper shows that auditory conceptual navigation recruits spatial grid-like computations in the entorhinal-hippocampal system, as evidenced by fMRI and behavioral experiments.

This study shows that the entorhinal cortex represents action affordances in conceptual spaces, as reflected in eye movements and neural patterns.

This study investigates how early blindness affects grid-like coding in the entorhinal cortex and finds altered symmetry patterns compared to sighted individuals.

The paper investigates whether heading direction in different brain regions is encoded in allocentric or egocentric coordinates, finding that superior parietal and retrosplenial regions use an egocentric code while the entorhinal cortex uses an allocentric code.

This study shows that mental search involves egocentric vector representations and restructured grid maps in the parietal cortex during conceptual task performance.

This study shows that covert attentional movements can elicit grid-like neural responses in humans using MEG and frequency tagging.

The paper investigates the temporal dynamics of abstract and concrete semantic representations using MEG, finding early frontotemporal activation for both and later occipito-temporal responses to concrete features.

The paper investigates shape representation in the human brain by comparing early blind and sighted participants, finding that the inferolateral occipitotemporal cortex (ILOTC) encodes shape information independently of visual experience.

The paper investigates how early blindness affects brain networks involved in spatial hearing, finding enhanced motion direction coding in hMT+/V5 and reduced coding in hPT in blind individuals.

The paper investigates neural responses to narrative and argumentative texts using fMRI, finding shared and distinct brain network activations.

The paper investigates how abstract and concrete knowledge is organized and retrieved in the anterior temporal lobe, finding that a dorsal-to-medial gradient emerges late in word processing with semantic information converging in the ATL.

The paper investigates whether vision is necessary for categorical organization in the VOTC by comparing fMRI responses to sound categories in sighted and blind individuals.

The paper investigates how visual deprivation affects conceptual retrieval by comparing neural activity in early-blind and sighted individuals during a perceptual similarity task.

This study shows that occipital cortex in early blind individuals synchronizes with speech acoustic fluctuations and has altered connectivity related to speech intelligibility.
