Human Perceptual Decision Making fMRI Data from Face/House Task

2020 fMRI data from a study dissociating evidence accumulation and choice maintenance in human perceptual decision making. The dataset contains brain activation patterns from participants performing a face/house discrimination task under delayed and self-paced response conditions. It was created by Mads Lund Pedersen and published under a CC0 license.

Use Cases

• Analyze fMRI activation patterns in dorsomedial prefrontal cortex and right inferior frontal gyrus for evidence accumulation processes.
• Model decision maintenance signals using activation data from frontal pole, temporal gyri, and precuneus regions.
• Compare brain activity between delayed and self-paced response conditions in the face/house discrimination task.

Strengths

• Data is associated with a peer-reviewed scientific study published in 2020.
• Includes results from a quantitative reverse inference meta-analysis to differentiate regional functions.
• Explicitly models and compares two dissociated cognitive processes: evidence accumulation and decision maintenance.

Limitations

• Sample size (number of participants or scans) is not specified in the provided metadata.
• The specific file formats, data size, and structure (rows/columns) are unknown.
• Data is from a single, specific experimental task (face/house discrimination), limiting generalizability.
