Il Cervello in Relazione con i Fenomeni Psichici. Studio sulla morfologia degli emisferi cerebrali dell'uomo, Torino, 1895. P. 89.
This is a work of great merit, in which the author compares the structure of the brain of man with that of other primates; he then treats of the morphology of the brain in different races, in criminals, in the insane, in deaf mutes, and in microcephales. An extremely interesting chapter is that devoted to the assumed difference of the cerebral hemispheres in the two sexes, containing statistical tables constructed by Dr. Mingazzini himself and others. Although he mentions certain minor differences that have been noticed by different observers, he summarises his own opinion by the statement that, "from the numerous but incomplete observations upon this subject, it may be concluded with certainty that essential differences do not exist" (si può inferire quasi con certezza che differenze essenziali non esistono).
