Creates a hippocampus-specific atlas from the Olsen MTL atlas, with optional
anterior-posterior subdivisions.
Usage
get_hipp_atlas(outspace = NULL, apsections = 1)
Arguments
- outspace
Optional NeuroSpace object for resampling
- apsections
Integer specifying number of anterior-posterior divisions.
Default: 1 (no subdivision)
Value
A list with class c("hippocampus", "atlas") containing:
- name
Character string "hippocampus"
- atlas
NeuroVol object with hippocampal parcellation
- ids
Integer vector of region IDs
- labels
Character vector of region labels
- hemi
Character vector of hemisphere designations
- cmap
Matrix of RGB colors for visualization
- orig_labels
Full labels including hemisphere information
Details
This function extracts hippocampal regions from the full MTL atlas and can
subdivide them into anterior-posterior segments. The resulting atlas maintains
bilateral organization and can be used for targeted hippocampal analyses.
Examples
if (FALSE) { # \dontrun{
# Basic hippocampal atlas
hipp <- get_hipp_atlas()
# With anterior-posterior subdivisions
hipp_ap <- get_hipp_atlas(apsections = 3)
} # }
