Sreenivasan Data: Neuroimaging of Subcortical Connectivity for Attention Bias

Neuroimaging data from 22 subjects includes structural images, superior colliculus volumes, and tractography files connecting it to 68 cortical and subcortical regions. The dataset is associated with a research paper by Varsha Sreenivasan on attention's effects on spatial choice bias. It is shared on paperswithcode under an Open Access license.

Use Cases

• Analyze structural brain connectivity based on tract files between the superior colliculus and cortical/subcortical regions.
• Visualize 3D renderings of the superior colliculus and other regions using the provided .vtk files.
• Reproduce correlation analyses from the associated research paper using the included analysis scripts.
• Study the relationship between specific subcortical nuclei (e.g., subthalamic nucleus, substantia nigra) and attention-related brain function.

Strengths

• Includes data from 22 distinct subjects, providing a basis for group-level analysis.
• Contains multiple data modalities per subject: structural MRI, region-of-interest volumes, and tractography files.
• Provides analysis scripts for reproducing the figures and results of the associated research paper.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
