title: Research advances made in the avian brain and their relevance to poultry scientists.
abstract: The year 2014 marked the tenth anniversary since the sequence of the chicken genome was published. Two other publications occurred during that time frame in different disciplines, and all 3 have affected poultry scientists. The purpose of this paper is to briefly review 2 publications that are better known to those in animal agriculture. The third paper will be addressed in more detail because it is one that many in poultry science probably have not read. The subject matter involves the avian brain and its future impact and is related to an announcement made by the president of the United States in April 2013. Due to the recent, rapid advances in the understanding of the vertebrate brain and behavior, a national goal was announced by President Obama to map the human brain in more detail than ever before to accelerate the understanding of brain function in health and disease. The main objective is to review the third paper published a decade ago to show that it laid the foundation for the chicken and other avian species to serve as relevant animal models to advance the understanding of the human brain. Emphasis will be placed on the forebrain. The overall goal is to show that the brain of birds is not that different from the mammalian brain and therefore can serve as an excellent comparative biomodel to understand fundamental principles of brain structure and function.
