Word Stimuli Summary for Intracranial Recording Study on Semantic Processing

19 human neurosurgical patients with epilepsy participated in a single-word reading concreteness judgement paradigm. The dataset contains summary information for word stimuli used to study high-frequency brain activation and intercortical communication. It was authored by Elliot Murphy and last updated on 2026-03-25.

Use Cases

• Modeling brain activation differences for concrete vs. abstract words based on high-frequency signatures.
• Analyzing directed information flow in cortical cascades based on intercortical communication metrics.
• Studying the causal role of specific brain regions like ventrotemporal cortex using cortical stimulation results.
• Investigating semantic representation invariance for mid-range concreteness words based on participant judgement data.

Strengths

• Data is derived from intracranial recordings in 19 patients, offering high spatiotemporal resolution.
• Includes results from cortical stimulation, providing causal evidence for region involvement.
• Released under a permissive CC-BY-4.0 license.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
