What are we, humans? This simple question of my youth has been driving my life-long scientific interests and career. Initially this led me to tackle lower vertebrates such as toads, salmons and lampreys. Through my first 10 years of struggle, seeking what we used to be during the last 500 million years, I recognized that CNS of humans (Primate) and lampreys (Agnatha) are composed of same set of molecules constructed on identical design. These are same but definitely different. I therefore redirected myself to birds, as birds constitute the other taxonomic branch toward high faculties, the other way than primates. During my bird era up to today, I have been fascinated by the fashion, in which the newly hatched domestics chicks show human-like rational/irrational behaviours in economical decision making and social challenges. Most recently, I am working on the seemingly classical issues of imprinting, because its impairment shares many features with ASD (autism spectrum disorder) in humans. I am tracking this by using pharmacology, electrophysiology, with some aids of molecular biology of developmental biology. The next step will be the number sense, math logics, and their fundamentals.
