When Melodies Cue Memories: Electrophysiological Correlates of Autobiographically Salient Music Listening in Older Adults Open
Autobiographical memory is essential for older adults, providing a foundation for self-identity. Although healthy aging is accompanied by changes in memory retrieval, musical memory remains relatively unaffected, suggesting music may serve…

Scene-sensitive medial temporal lobe subregions are recruited for the integration of non-scene stimuli Open
A hallmark feature of episodic memory is the ability to flexibly recombine information across episodes to form new associations and guide behavior. This process, termed associative inference, relies on the hippocampus and surrounding media…

A vision transformer approach for fully automated and scalable dementia screening using clock drawing test images Open
INTRODUCTION The clock drawing test (CDT) screens for dementia but requires trained scorers and lacks standardized criteria. Thus, we developed an automated vision transformer (ViT)‐based diagnostic system with convolutional neural network…

Differential reliance on sensory reinstatement and internally transformed representation during vivid retrieval of visual and auditory episodes Open
Auditory memory is considered less detailed yet more durable than visual memory, implying a modality-specific memory retrieval process. We used fMRI and multivoxel pattern analyses to examine how 25 participants encoded and retrieved natur…

Stimulus-Driven Vividness in Visual Memory: Introducing the Concept of ‘Vividability’ Open
Objective memory performance is tied to remembered stimuli and their constituent properties, however it is not clear whether the subjective experience of remembering an event is determined by stimuli and their features. The consistency of …

Individual Differences in Visual vs. Semantic Neural Reactivation: Evidence from Severely Deficient Autobiographical Memory (SDAM) Open
Visual memory is intricately linked to the reinstatement of low-level visual features, such as edges and luminosity, within the early visual cortex. However, individuals with Severely Deficient Autobiographical Memory (SDAM) cannot vividly…

Neural reactivation and judgements of vividness reveal separable contributions to mnemonic representation Open
Mnemonic representations vary in fidelity, sharpness, and strength-qualities that can be examined using both introspective judgements of mental states and objective measures of brain activity. Subjective and objective measures are both val…

Multivariate FMRI Signatures of Learning in a Hebb Repetition Paradigm With Tone Sequences Open
Important information from the environment often arrives to the brain in temporally extended sequences. Language, music, actions, and complex events generally unfold over time. When such informational sequences exceed the limited capacity …

Concurrent feature-specific reactivation within the hippocampus and neocortex facilitates episodic memory retrieval Open
The hippocampus is a key brain region for the storage and retrieval of episodic memories, but how it performs this function is unresolved. According to the hippocampal indexing theory, the hippocampus stores an event-specific index of the …

Detailed Episodic Memory Depends on Concurrent Reactivation of Basic Visual Features within the Posterior Hippocampus and Early Visual Cortex Open
The hippocampus is a key brain region for the storage and retrieval of episodic memories, but how it performs this function is unresolved. Leading theories posit that the hippocampus stores a sparse representation, or “index,” of the patte…
