Maternal Chronic Stress Induces Premature Telencephalic Vesicles Development

Exposure to physical or psychological stress causes brain damage ranging from minimal behavioural alterations to different neurodegeneration degrees implying the overproduction of oxidative-nitrosative compounds, apoptosis and cell proliferation. In the present investigation, we have analysed the ef...
