Topic: Macaca genus

Leveraging ethological studies on the Macaca genus, 23 species have been ordered on a 4-grade social tolerance scale based on 18 behavioural traits, including counter-aggression and reconciliation rates (Grade 1, e.g., M. mulatta, to Grade 4, e.g., M. tonkeana). However, the neuroanatomical correlates of interspecific differences in macaques’ social behaviours remain unknown. To address this, we fostered a unique collection of 34 post-mortem samples from 11 macaque species, combining Strasbourg-based 7T MRI scans with data from existing databases (PRIMate Data Exchange, Japan Monkey Centre, Ox
