    ABC: Avian models for studying xenoestrogens action on brain and behavior

    Date: 26th August AM
    The disturbance of hormonal systems by xenoestrogens, particularly during the sensitive periods of organogenesis and sexual differentiation of the brain, can alter the functionality of the reproductive organs and the neurochemistry and organization of the cerebral circuits, and thus, the behavioral responses of the individuals exposed to these substances. Several researches performed in recent years have investigated subtle modifications of the animal behaviors (reproductive, aggressive) induced by xenoestrogens that are probably related to alterations of specific neural pathways. The aim of this workshop is to focus on the behavioral studies and on the avian brain as one of the more powerful tools to investigate xenoestrogens effects.

    Keywords: neuroscience, birds, xenoestrogens
