Allocortex |
Three-layered cortex (hippocampus and piriform cortex) which exhibits peculiar characteristics prenatally and was labelled as allogenetic (Vogt 1910, Sanides 1969) |
Cortical confluence |
Mergence of cortical types (iso- and allo-cortex) in the mesiotemporal lobe (Paquola et al., 2020) |
Cytoarchitecture |
Organisation of cells |
Equivolumetric |
Intracortical surfaces constructed in such a way that preserves the volume of each strata (Waehnert et al., 2014; Wagstyl et al., 2019) |
fsaverage |
Standard surface in FreeSurfer |
fs_LR |
Standard surface in HCP (Van Essen et al. 2012) |
Gradients |
Graded spatial variations in a neurobiological feature |
Isocortex |
Majority of the cortex, which exhibits six layers prenatally. Short for isogenetic cortex (Vogt 1910, Sanides 1969) |
Microstructure profile |
A sequence of intracortical intensity values (staining or MRI) running from the pial to white matter, ie: in the direction of cortical column (Paquola et al., 2019) |
Moments |
Quantitative measures related to the shape of a microstructure profile |
Parcellated |
Aggregation (usually averaging) of a neurobiological feature within a pre-defined cortical area |
Sensory-fugal |
A functional characterisation of the cortical gradient that runs from externally-focused primary sensory areas to limbic areas that are relatively decoupled from environmental input (Mesulam 2000). The term fugal is related to a fugue-state; a mental state that is decoupled from external reality. |
Vertex |
A point on a cortical mesh. In standard practice, the organisation of vertices is preserved across different depths (ie: grey and white matter boundaries), when the meshes come from the same reconstruction procedure. |
