The key to understand the rise of mind should be found in communicative behavior

Our research hypothesis is “Communication shaped our mind”. To experimentally validate this hypothesis, we study animal and human communicative behavior by biopsychological approaches. Our experimental animals include rats, birds (Bengalese finches, Zebra finches, and Java sparrows), and humans. We set up behavioral paradigms that require cognitive or communicative faculties, and simultaneously measure brain activities such as single unit response, cellular gene expressions, electroencephalograms, and functional MRI. We aim to investigate correlational and causal relations between neural activities and behavior. We hope to understand how mind arouse based on these research activities.
