Activity

Hormones are among the most important environmental factors for the development, differentiation and functioning of the nervous system. In particular, our research group is interested in the interactions between steroid hormones, neural circuits and behaviours dependent on steroids, such as sexual behaviour and the behavioural response to stress.

Explaining these interactions can be crucial to understand the causes that lead to some behavioral disorders (anorexia, depression) or neurodegenerative diseases (Parkinson's, multiple sclerosis) in which there are evident gender differences, such that one sex has a greater prevalence or severity of the disease than the other.

In addition, a minimum alteration of hormone balances - determined by exposure to chemical compounds able to interact with their receptors - can induce harmful effects on the behavior and physiology of animals and humans.

The experimental studies in this field are useful to understanding what threshold values ​​may be acceptable and if certain dysfunctions can be caused by exposure to these environmental factors.

Our main research lines currently include:

- The role of androgens and estrogens in the differentiation of the brain circuits involved in controlling the reproduction and social behavior.

- The role of neurosteroids and some neuropeptides in affective disorders, in order to understand whether gender differences that occur in these diseases may have a basis related to the effects of endogenous neurosteroids.

- Short- and long-term effects of neurosteroids on adult sexual neurogenesis.

- Effects of Endocrine disruptors (xenoestrogen and xenoandrogen) exposure on the differentiation of brain circuits that control reproduction and feeding behavior.
