Human Brain Activity and Connectivity During Response Inhibition

A collection of brain activity and functional connectivity measurements from a study investigating the role of the intraparietal sulcus in response inhibition. The study employed a stop-signal task and transcranial magnetic stimulation, with behavioral data including stop-signal reaction time (SSRT). The dataset was published by Takahiro Osada in 2020.

Use Cases

• Analyze the relationship between intraparietal sulcus activation and stop-signal reaction time (SSRT) during response inhibition tasks.
• Examine resting-state functional connectivity between the intraparietal sulcus and frontal regions like the inferior frontal cortex.
• Model the temporal effect of transcranial magnetic stimulation on SSRT when applied 0-30 ms before stopping.
• Compare brain activity patterns between the intraparietal sulcus and temporoparietal junction during response inhibition.

Strengths

• Data is associated with a published neuroscience study examining a specific executive function.
• Includes multiple measurement modalities: brain activity, functional connectivity, and behavioral performance (SSRT).
• Dataset is openly available under the CC0 1.0 public domain license.

Limitations

• The specific number of subjects, rows of data, and file structure are unknown.
• Data is from a single study, limiting generalizability to broader populations or conditions.
• The dataset is from 2020 and may not reflect the latest methodologies in the field.
