Get cortical brain surface mesh — get_cortical

Retrieves a cortical brain surface mesh for the specified hemisphere and surface type. All surfaces are fsaverage5 resolution (10,242 vertices, 20,480 faces per hemisphere).

Usage

get_cortical_mesh(hemisphere = c("lh", "rh"), surface = .cortical_surfaces)

Arguments

hemisphere: "lh" or "rh"
surface: Surface type: "pial", "white", "midthickness", "semi-inflated", "sphere", "smoothwm", or "orig"

Value

A list with vertices (data.frame with x, y, z) and faces (data.frame with i, j, k, 1-based indices). Has attribute face_index_base = 1L.

Examples

mesh <- get_cortical_mesh("lh", "pial")
nrow(mesh$vertices)
#> [1] 10242
