Simultaneous EEG-fMRI Recordings of 16 Participants During Visuospatial Tasks

Encompassing simultaneous EEG and fMRI recordings from 16 participants performing a visuospatial attention task involving faces and landscapes. Created by Johanna M. Zumer and published in 2020, the data captures alpha band (8–13 Hz) oscillations and BOLD signals to map information gating from the visual cortex to the ventral stream.

Use Cases

• Modeling the correlation between alpha band power and BOLD signal intensity in ventral object-selective regions
• Analyzing the top-down control of visual alpha activity by the dorsal attention network
• Investigating neural gating mechanisms by comparing contralateral and ipsilateral alpha power

Strengths

• Simultaneous EEG and fMRI recording providing multimodal temporal and spatial resolution
• 16-participant sample size for specialized neuroimaging research
• Includes representationally specific BOLD signals for faces and landscapes

Limitations

• Small sample size of 16 participants limits statistical power for population-level inferences
• Task-specific focus on visuospatial hemifields may not generalize to other forms of attention
• Potential for signal noise inherent in simultaneous EEG-fMRI acquisition
