title: [Quantitative observations of non-neuronal and neuronal cells of the mammillary bodies during postnatal development].
abstract: The mammillary bodies are already shaped in the last stages of the fetal development, and you can differentiate clearly in them the medial mammillary nucleus (MMN) and lateral mammillary nucleus (LMN). All this allow to study the variations in cellular density, the relation between neuronal and glial cells, so as the number of nucleoli present in the neuronal cells and the nucleolar area variations through the postnatal development (0N, 2N, 4N, 8N, 16N and adult). The results show, demonstrate a different behaviour in the cellular stabilization and migration of the MMN and LMN, so as a cellular differentiation after 4N in both nucleus. All this is discussed with the data obtained from the nucleolar activity, as an index of synthesis and reflection of the neuronal maturing.
