Project title: MCH neurons in chick embryos
Project description (50-100 words suggested): Melanin-concentrating hormone (MCH) is a neuropeptide found in the lateral and posterior hypothalamus in mammals and birds, and is involved in modulating several physiological and behavioural functions, including the sleep-waking cycle. MCH neurons are silent during wakefulness, and are active during slow wave sleep (SWS) and even more during rapid eye movement sleep (REMS). EEG recording of chick embryos showed the appearance of SWS and REMS before hatching. The development of MCH neurons has been studied in rats, where they appear as early as the 13th day of embryonic life. No information is available on the MCH system development in birds. In this project, the development of MCH neurons will be studied in chick embryos with the goal of correlating their development with the appearance of EEG activity. MCH-producing neurons will be visualized in brain sections obtained from embryos of different ages by using standard immunohistochemical protocols. The total number of labelled neurons will be estimated using a Leica microscope and the optical fractionator method of stereology.
