AAL90: Cortical and Subcortical Brain Region Parcellation Atlas

A list of 90 brain regions from the AAL90 parcellation atlas, comprising 45 cortical and subcortical areas per hemisphere. The dataset was authored by Carlos Coronel-Oliveros and last updated on May 13, 2026. It is available as a 9.5 KB XLS file under a CC-BY-4.0 license.

Use Cases

• Mapping fMRI data to specific brain regions based on the AAL90 parcellation scheme.
• Simulating fMRI activity across the listed cortical and subcortical areas.
• Comparing EEG and fMRI simulation setups by referencing the regions marked for exclusion from EEG.

Strengths

• The atlas provides a standardized list of 90 brain regions, enabling consistent referencing across studies.
• It explicitly distinguishes between regions used for fMRI simulations and those excluded for EEG, clarifying its intended application scope.
• The dataset is small (9.5 KB) and in a widely accessible XLS format, facilitating quick inspection and integration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analyses.
• The description metadata is limited; actual data quality and completeness require manual inspection.
