Resumen
This investigation was undertaken in order to quantify the effects of early polysensorial enrichment on the
development of cortical pyramids, located in the parietal cortex of rats simultaneously submitted to protein-energy undernutrition. A
short period of stimulation during suckling significantly decreases the cellular density in the cortical plate (phylogenetic-ontogenetic
evolutionary index). Results suggest that the cerebral cortex develops according to a sophisticated neuronal network, which exhibits a
notable degree of structural specificity, regulated by genetic and environmental clues. The most obvious prediction is that environmental
influences are probably transduced as a structural expression in the developing parietal cortical plate.
