The paper examines implicit associative memory in younger and older adults, finding preserved neural correlates in occipitotemporal and frontal regions, with perirhinal cortex involvement in both age groups.

This study investigates how transcranial magnetic stimulation (TMS) improves memory in Mild Cognitive Impairment by modulating semantic representations in parietal cortex and hippocampus.

The paper investigates how structural connectivity in the brain influences visual and semantic representations in older adults, finding that connectivity mediates age-related declines in perceptual representation and supports semantic memory.

This study investigates how semantic information affects visual false memory using fMRI, revealing distinct neural pathways that bias memory toward perceptual specificity or semantic generalization.

This study uses large language models to map how the brain encodes relational semantic information, showing distinct brain regions represent concepts and their relationships.

This study investigates how neural reinstatement supports memory for color and location, showing distinct mechanisms for each and the role of language in color memory.

This study shows that older adults use semantic schemas more effectively than young adults for memory encoding, mediated by distinct cortico-hippocampal interactions.

This paper introduces trial-level RSA (tRSA) to assess neural representation at the trial level, finding it more sensitive and theoretically appropriate than classic RSA.

The paper investigates how brain connectivity fluctuates between high and low prediction error states using fMRI and EEG data, showing these fluctuations correlate with cognitive operations.

The paper investigates how information coding transitions from modular to distributed in the ventral stream using fMRI data, finding that occipital regions are modular while inferior temporal regions are distributed.

The paper investigates whether semantic dimensions account for neural correlates of object memorability using multimodal datasets and fMRI data.

This study uses dual-coil TMS-EEG to investigate bilateral brain mechanisms in healthy aging and mild cognitive impairment, finding frequency-specific responses to bilateral rTMS.

This study shows that cognitive function in older adults depends on the alignment between functional and structural brain networks, with this dependency being strongest in high-order and subcortical networks.

This study uses concurrent fMRI and TMS to show that increasing TMS intensity alters functional connectivity between visual and non-visual networks, affecting motion discrimination performance.

The paper investigates age-related changes in perceptual and mnemonic representations using fMRI, finding dedifferentiation in sensory features and hyperdifferentiation in categorical features in older adults.

The paper identifies distinct subsystems within the posterior medial network during movie watching and shows their functional roles in event cognition.

This study tests if functionally guided rTMS can modulate amygdala activation via its connectivity with the medial prefrontal cortex, finding increased activation post-rTMS.

The paper examines how visual and semantic representations predict memory performance in perceptual and conceptual tests using fMRI and RSA.

This paper shows that structural controllability predicts working memory benefits from brain stimulation and correlates with functional modulation of memory demand.

The paper examines age-related differences in PFC network connectivity during episodic memory retrieval, finding increased PFC integration and reconfiguration in older adults associated with better performance and compensating for MTL deficits.

This study investigates how different intensities and timings of TMS affect visual perception and brain activity, finding that lower intensities can enhance performance.

This study applies long-interval paired-pulse TMS to motion-sensitive visual cortex but finds no changes in motion perception.

This study tests if online rTMS improves working memory in older adults, finding it instead decreases accuracy in high-demand tasks.

The paper investigates how the brain maintains and manipulates information during working memory tasks, finding dissociable neural networks for these processes and increased segregation under higher demand.

This study examines the associations between cardiovascular risk factors and white matter structure in aging, finding that systolic blood pressure, diastolic blood pressure, and heart rate independently impact white matter health.

The paper shows that physical activity preserves frontal white matter integrity and reduces age-related slowing in a population-based sample.

This study uses RSA and ERS analyses to show that 5Hz rTMS enhances memory representations in the PFC and MTL compared to 1Hz.

The paper uses structural equation modeling to integrate functional and structural connectivity data, revealing independent and distinct contributions of these connectivities to associative and item memory in older adults.

The paper investigates how local network deficits in aging are compensated by global network over-recruitment using rTMS and finds that 1-Hz rTMS increases global connectivity while reducing local activity.
