“…It is a branch of the maxillary artery stemming from the external carotid, commonly entering the endocranium through the foramen spinosum (see Saban 1995;Grimaud-Hervé 1997). The phylogenetic origin of these vessels is still debated (Diamond 1991(Diamond , 1992Falk & Nicholls 1992;Falk 1993), as it could not be homologous within the anthropoids variability.…”

“…Draws of the MMV from fossil specimens were collected from the literature (Saban 1995;GrimaudHervé 1997) and checked directly on the endocast collections at the Istituto Italiano di Paleontologia Umana (Roma), at the Museo di Antropologia G. Sergi, Università La Sapienza (Roma), and at the Institut de Paleontologie Humaine (Paris). The sample includes 54 hemispheres from 29 individuals (Table I), grouped into three operational taxonomic units: Asian Homo erectus (N ¼ 22), Neanderthals (N ¼ 15), and early modern humans (N ¼ 17).…”

The middle meningeal vascular network leaves its traces on the endocranial surface because of the tight relationship between neurocranial development and brain growth. Analysing the endocast of fossil specimens, it is therefore possible to describe the morphology of these structures, leading inferences on the cerebral physiology and metabolism in extinct human groups. In this paper, general features of the meningeal vascular traces are described for specimens included in the Homo erectus, Homo neanderthalensis, and Homo sapiens hypodigms. The complexity of the arterial network is quantified by its fractal dimension, calculated through the box-counting method. Modern humans show significant differences from the other two taxa because of the anterior vascular dominance and the larger fractal dimension. Neither the fractal dimension nor the anterior development are merely associated with cranial size increase. Considering the differences between Neanderthals and modern humans, these results may be interpreted in terms of phylogeny, cerebral functions, or cranial structural network.

“…In anthropology, paleontology, and bioarchaeology, endocranial vessels can be analyzed by studying the traces they leave on the endocranial surface or in the bone. Two neurocranial vascular systems can be observed on osteological or fossil remains: the middle meningeal and the diploic system (e.g., Saban, 1995;Hershkovitz et al, 1999;Bruner et al, 2005Bruner et al, , 2009Bruner et al, , 2011bBruner and Sherkat, 2008;Bruner, 2015). The neurocranial formation is mainly based on a secondary bone deposition which is related to the expansion of the brain (Moss and Young, 1960;Enlow, 1968).…”

4 Katedra antropologie a genetiky člov eka, Univerzita Karlova, Czech Republic 5 Antropologick e odd elen ı P r ırodov edeck eho muzea, Narodnı Muzeum, Prague, Czech Republic ABSTRACT Cranial bone thickness varies among modern humans, and many factors influencing this variability remain unclear. Growth hormones and physical activity are thought to influence the vault thickness. Considering that both systemic factors and energy supply influence the vascular system, and taking into account the structural and biomechanical interaction between endocranial vessels and vault bones, in this study we evaluate the correlation between vascular and bone diameters. In particular, we tested the relationship between the thickness of the parietal bone (which is characterized, in modern humans, by a complex vascular network) and the lumen size of the middle meningeal and diploic vessels, in adult modern humans. Our results show no patent correlation between the thickness of parietal bone and the size of the main vascular channels. Values and distributions of the branching patterns, as well as anatomical relationships between vessels and bones, are also described in order to provide information concerning the arrangement of the endocranial vascular morphology. This information is relevant in both evolutionary and medical contexts. Anat Rec,
