Neurobiology: A Functional Approach, by Georg F. Striedter, is a seminal work published by Oxford University Press on October 2, 2015. This 1st edition delves into the fundamental questions of neurobiology by examining the problems that brains help organisms solve, exploring not just *how* the nervous system functions but also *why* it operates as it does. The text adopts an evolutionary, organismal, and experimental perspective, offering readers a comprehensive introduction to the field. With a significant focus on neural circuits and systems, Striedter masterfully connects the cellular and molecular aspects of neuroscience with its cognitive dimensions, providing a holistic understanding of the subject. Beyond presenting established facts and theories, Neurobiology: A Functional Approach illuminates the scientific process by highlighting the key experiments that have shaped our knowledge of the brain.
