Struct CorticalArea 

pub struct CorticalArea {
    pub cortical_id: CorticalID,
    pub cortical_idx: u32,
    pub name: String,
    pub dimensions: CorticalAreaDimensions,
    pub position: GenomeCoordinate3D,

Cortical area metadata (genome representation)

Pure data structure containing static genome metadata. Runtime operations and transformations are implemented in feagi-bdu.

Fields

cortical_id: CorticalID

Unique typed cortical identifier

cortical_idx: u32

Integer index assigned by ConnectomeManager

name: String

Human-readable name

dimensions: CorticalAreaDimensions

3D dimensions (width, height, depth in voxels)

position: GenomeCoordinate3D

3D position in genome space

cortical_type: CorticalAreaType

Cortical area type (encoding method and functional classification)

properties: HashMap<String, Value>

Additional user-defined properties Note: See PROPERTIES_STRUCT_MIGRATION_PROPOSAL.md for future struct-based design
