Dynamic and Integrated Synaptic Processing ... 137control suitable for the display of social behaviors, for which the MePD is a
relevant component in differently integrated brain circuits...” (Quagliotto et al.,
2008).
In conclusion, the MePD is part of the neural network for the elaboration
of social behaviors with the important property of being modulated
dynamically by the levels of gonadal hormones in circulation (expanding data
from Newman, 1999). The data reviewed here provide new insights for the
comprehension of sexually dimorphisms and the feminine specialization of
neural circuits, neuroendocrine secretion, and cyclic behavioral display in a
current animal model. They provide additional insights about the important
role of the rat MePD as a model for the study of the link between sex steroids,
the cellular specializations for synaptic processing, and the functional
organization of the nervous tissue in female rats.
