Information about the title group: Thematic volume on Neurobiology. Neurobiology balances established neurobiological foundations, such as the structure of the brain or fundamental functions, with current, ever-expanding insights from this relatively young science. The selection of topics is relevant for biology education at the qualification level. Topics include: nervous system and nerve cells, from stimulus to response, behavior and cognition. Information about the series: The Biosphere concept serves as both a textbook and a workbook. Following the 3+1 concept, the topics covered form self-contained units. The structure is easy for students to follow: three pages of information are followed by a page with material-related tasks or experiments. Selected examples accompany the content of the textbook pages in the spirit of exemplary learning.
