In the past decades, researchers have proposed several hypotheses to explain this finding, but none is definitive and some are possibly not mutually exclusive. Certain species diverge markedly (positively or negatively) from the mean of the ratio BM/BS expected for a particular taxonomic group. It is possible to define encephalization quotient (EQ) as the ratio between the actual BS and the expected brain size. Several cetacean species show higher EQs compared to all primates, except modern humans. The process that led to big brains in primates and cetaceans produced different trajectories, as shown by the organizational differences observed in every encephalic district (e.g., the cortex). However, these two groups both convergently developed complex cognitive abilities. The comparative study on the trajectories through which the encephalization process has independently evolved in primates and cetaceans allows a critical appraisal of the causes, the time and the mode of quantitative and qualitative development of the brain in our species and in the hominid evolutionary lineage.

Teodoro presso Acquedolci (Messina, Italia) è uno dei più importanti siti paleolitici del Mediterraneo. Dalle numerose campagne di scavo sono emersi i resti scheletrici umani di sette individui a differente grado di completezza e conservazione. Fin dai primi scavi ...

Neural correlates for the processing of face identity, expression, gaze direction and attractiven... more Neural correlates for the processing of face identity, expression, gaze direction and attractiveness are well described, but neurophysiological correlates for the perception of face gender are less understood. Here, we used morphing techniques to produce synthetic faces with graded perceivable gender and independent component analysis (ICA) of multifocal EEG to unravel neural signals correlated to processing and perception of face gender. We investigate possible neural correlates of face perception using scalp event-related potentials (ERPs) and dipole source analysis in a group of health observers. We isolated one signal source localised to the right parieto-temporal region with a latency of about 170 ms, whose latency correlates with perceived facial masculinity. In conclusion, our data prove that the right parieto-temporal regions play a fundamental role in face gender masculinity processing and perception in humans.
