Trial-level Representational Similarity Analysis

Preprint · February 13, 2026 Neural representation refers to the brain activity that stands in for one’s cognitive experience, and in cognitive neuroscience, a prominent method of studying neural representations is representational similarity analysis (RSA). While there are se ... Full text Cite

Understanding the mechanisms of lateral parietal memory modulation in Mild Cognitive Impairment

Preprint · 2026 The application of transcranial magnetic stimulation (TMS) to lateral parietal cortex has shown promise in improving episodic memory in older adults with Mild Cognitive Impairment (MCI). Previous work has suggested that such improvements are achieved by ac ... Full text Cite

Trial-level Representational Similarity Analysis.

Preprint · April 1, 2025 Neural representation refers to the brain activity that stands in for one's cognitive experience, and in cognitive neuroscience, the principal method to studying neural representations is representational similarity analysis (RSA). The classic RSA (cRSA) a ... Full text Link to item Cite

Increased sensorimotor and superior parietal activation correlate with reduced writing dysfluency in writer's cramp dystonia.

Preprint · March 21, 2025 Writer's cramp (WC) dystonia is a disabling brain disorder characterized by abnormal postures during writing tasks. Although abnormalities were identified in the sensorimotor, parietal, basal ganglia, and cerebellum, the network-level interactions between ... Full text Link to item Cite

Motor network reorganization associated with rTMS-induced writing improvement in writer's cramp dystonia.

Preprint · January 18, 2025 BACKGROUND: Writer's cramp (WC) dystonia is an involuntary movement disorder with distributed abnormalities in the brain's motor network. Prior studies established the potential for repetitive transcranial magnetic stimulation (rTMS) to either premotor cor ... Full text Link to item Cite

Mapping concept and relational semantic representation in the brain using large language models

Preprint · 2025 How the brain organizes semantic information is one of the most challenging and expansive questions in cognitive neuroscience. To shed light on this issue, prior studies have attempted to decode how the brain represents concepts. We instead examined how re ... Full text Cite

Semantic Dimensions Support the Cortical Representation of Object Memorability

Preprint · 2024 ABSTRACT Recent work in vision sciences contends that objects carry an intrinsic property, memorability, that describes the likelihood that an object can be successfully encoded and later retrieved from memory. It has been shown that object memor ... Full text Cite
