Abstract
Brain integration and modularity studies aim to analyse the covariation and interaction of this organ with different bony structures that make up the cranium. The brain morphology of Hominidae is largely variable and presents a series of integration patterns that may be due to both intraspecific and interspecific factors [1]. One of the keys to understanding the evolutionary mechanisms of our genus is to identify and quantify which integration patterns are shared and whether these can be applied to fossil species [2]. In the past decades, thanks to the application of new techniques and digital tools (mainly 3D), it has been possible to approach this problem from new perspectives. However, delving into studies about brain integration and modularity is crucial because of the complex interaction of brain lobes in the integration of the whole system [3]. The aim of this work is to quantify the covariation patterns of the different brain areas of the two phylogenetically closest extant Hominidae species: Homo sapiens and Pan troglodytes. The main goal is to detect shared or species-specific integration patterns that can later be applied to extinct hominin species.
