Data and code for: Between-species variation in neocortical sulcal anatomy of the carnivoran brain

This repository contains the data and code for the study "Between-species variation in neocortical sulcal anatomy of the carnivoran brain" by Boch et al 2026, eLife, https://doi.org/10.7554/eLife.100851.3. It includes cortical surface reconstructions of 32 carnivorans, generated using precon_all; Benn et al 2025), along with digital sulcal masks produced with Connectome Workbench (Marcus et al., 2011) and behavioural characteristics of the described species.

Codemerge_sulci.py combines individual sulcal masks (border files) into a joint atlas file. sulci-measurements.ipynb measures the length of each sulcus on the individual cortical surfaces and saves the output in the derivatives subfolder (applied in Boch et al, 2026, eLife). Both scripts require Connectome Workbench to be installed. carnivoran_sulcal-anatomy_length.Rmd performs the statistical analysis described in the Methods section of the eLife article; all necessary R libraries are listed within the script.
