High-density electroencephalogram (EEG) was used in a longitudinal study in infants at 4-5 months and later at 9-10 months to study brain electrical activity as the participants were presented with simulated forward and backward motion from optic flow at two different speeds, with a static inter-stimulus between each motion condition. The aim of the research was to investigate the evoked and oscillatory brain responses to the motion stimuli in infants, with particular attention directed at the N2 component, as well as to the oscillatory activity recorded in the occipital and parietal regions of the brain. The results showed a main effect of direction, indicating that infants had faster processing times for forward than the backward optic flow, as shown by longer latencies for the latter condition. Further, low speed was more easily processed than high speed, for both directions, but only by the older infants. Lower amplitudes were recorded for the older infants, and it was found that speed affected amplitude for backward motion only, with high speed displaying higher amplitudes, regardless of age. Additionally, direction affected amplitude for low speed only, with forward motion displaying higher amplitudes. Finally, observation of the oscillatory activity revealed theta- and alpha- desynchronizations at both ages when the TSEs for the motion conditions were compared to the static condition, with synchronizations being recorded for the static condition. However, no decrease in low-frequency activity was registered at the second testing, contrary to the expectations. It was concluded that the infant brain specializes and becomes more sensitive to visual motion stimuli as it matures.

The archaeological excavations in Vico III Lanusei, within the urban area of Cagliari, were carried out between 1996 and 1997. The work was supervised by Donatella Mureddu of the Archaeological Authorities for the Provinces of Cagliari and Oristano. The stratigraphic excavation of the site has brought to light various inhabited and funerary areas, testifying to their use from the late republican period through to the Middle Ages. Differing types of burial have been discovered in the area. In particular, one was dug directly into the rock, three were in coffins and two were Capuchin type burials. In this paper a description is provided of the results of the anthropological study of the human skeletal remains found in the burial dug directly into the rock. In the grave there were four infants in a supine position, placed on a later dates.
