This line of research on human paleoneurology studies brain evolution in fossil species, combining functional craniology and evolutionary neuroanatomy. The line includes studies on the morphology of the skull and brain in extinct and present species, and the analysis of the vascular features of the neurocranium. Cranium and brain are analyzed with digital anatomy techniques, using geometric models and multivariate statistics. Finally, lines of research into cognitive archaeology combine human evolution and psychometric methods.
