Raw fMRI Data for 40 Subjects in Object Identification Study

Raw fMRI data from 40 subjects for a study on brain-behavior relationships during object identification. Each subject contributed one MPRAGE anatomical scan and two multi-echo, slow event-related fMRI overt picture naming runs, formatted in BIDS. The data supports trial-level analysis as published in Frontiers in Human Neuroscience (2024).

Use Cases

• Analyze trial-level brain-behavior correlations using multi-echo fMRI data from overt picture naming runs.
• Process BIDS-formatted MPRAGE anatomical scans for subject-specific brain structure mapping.
• Investigate slow event-related fMRI signals during object identification tasks across 40 subjects.

Strengths

• Data from 40 human subjects provides a substantial sample for neuroimaging analysis.
• Includes both anatomical (MPRAGE) and functional (multi-echo fMRI) data for each participant.
• Data is structured in the standardized BIDS format, facilitating reproducible analysis.

Limitations

• The dataset is raw, requiring significant preprocessing (e.g., motion correction, normalization) before analysis.
• Specific sample demographics, clinical characteristics, or behavioral performance metrics are not described in the provided input.
• The data size (9.6 GB) indicates a medium-scale study, which may limit power for detecting subtle neural effects.
