Fishes have adaptively radiated to various aquatic environments while conserving the basic physiological and behavioral features seen in a wide range of vertebrate species. Recently, notable progress has been made in studies in relation to brain mechanisms that play roles in cognitive and emotional behaviors such as spatial learning, fear conditioning, aggression and appetitive behavior. Quantitative observations of selected behaviors in conjunction with modern neurobiological techniques have enabled comparative analysis of physiological, morphological and developmental basis of higher-order brain functions in fishes. Selection and assessment of behavioral repertoires in fishes which can be directly or indirectly compared with other vertebrates are also important for revealing brain mechanisms conserved through vertebrate evolution. This session aims to explore biological basis of cognition and emotion and the underlying neural mechanisms in vertebrates by focusing on fish behavior and brain function.
