To explore the effect ofthe soybean milk, as complement of the diet on the loss of neurons in the central nervous system and oyer spacial memory. Material and methods: From the weaning and to the 15 months of age male Wistar rat were assigned to two diets: A) balanced food and water (control); B) balanced food and soybean milk. For the histological studies, eyery three months, the animals were sacrified their brains extracted, fixed and paraffin included. Sections of 10¡.tm were dyed with Blue of Toluidina. The neurons of the hippocam­pus were counted under optical microscope. For spacial memory a water maze was used. Results: The animals, whose diet was complemented with soybean milk, lost less neuron than the controls in layers CA2 and CA3. However, there were not significant differences in the retention of the maze between the studied groups. Conclusions The antioxidant capacity ofthe soybean could explain, the results presented here.
