<p>Because the primary source of activity of the EEG is in the cortical neural processes, the change in the EEG pattern in newborn infants during the feeding processes may be indicative of a shaping of a primitive protomental image, i.e. a sensory memory formation at the cortical level, that starts after birth and runs in parallel to the deep automatic brain functions regulating the reflexive and autonomous neural events of the nursing exchanges. This may be important, since the participation of the cortex in the effects of newborn feeding has not been recognized before and its plausible implications for the bodily self experience (the nascent body ego) is so far unknown, in contrast to the relatively well-known role of the brain stem and the diencephalic structures that regulate the sucking reflex, the homeostasis of vital biological func- tions and the basic affective processes (Damasio, 1996, 2000; Lehtonen, 2006; Watt, 2003).</p><p>In another study penetrating the same developmental phenomena, Paul et al. (1996) have shown in infants from the age of 2 to 26 weeks that feeding is connected with an amplitude increase and a growing degree of synchronization in the EEG, with an exception of the age of 10 weeks, when no significant EEG changes were recorded. These observations are quite in line with our findings. Chugani et al. (1987) have shown in PET recordings that during the first weeks of life there is an increase in blood flow in those brain structures (brain stem, cerebellum, striatum and the sensory areas of the cortex) that participate in nursing responses. These references, though short and selected, illu- minate the wide scope of physiological phenomena that are connected with nursing and the multiple changes in the psychophysiological state of the offspring that occur in infant care.</p>
