Emma M. Karlsson is a postdoctoral researcher at Ghent University, Belgium, whose work focuses on the structure and function of the brain.Sebastian Ocklenburg is Professor of Research Methods at MSH Medical School Hamburg, Germany, where he conducts research on several topics within psychobiology.

"An accessible, well-researched and captivating introduction to how biology informs human behaviour. Methodology is explained well, enabling students to understand a range of biological measures and, crucially, their significance. This thoughtful, focused and quirky approach, making clever use of diagrams and vivid examples, will help students navigate this vast area confidently and with understanding.”Lynn Wright, C.Psychol, AFBPsS and Scott Hardie C.Psychol, AFBPsS, Faculty of Applied and Social Sciences, Abertay University, Scotland, UK“In this book, Karlsson and Ocklenburg present a succinct yet incredibly broad and accessible guided tour of psychobiology. The slim volume covers historical people and perspectives that were key to establishing the field, through to modern societal factors impacting behavioural and brain function and methods for measurement. This book is an essential resource for all psychology students and an enticing read for anyone with a passing interest in psychobiology.”Gillian S. Forrester, Professor of Comparative Cognition and Academic Lead for Public Engagement, University of Sussex, England, UK“By distilling a wide-ranging literature into crisp explanations with clear, real-world relevance, this book makes a complex domain highly accessible. It is an indispensable guide to neurodiversity, stress biology, climate psychobiology, and intelligence – either biological and artificial – delivered with clarity and insight.”Silvia Paracchini, PhD, FRSB, FRSE, Professor of Neurogenetics and Genomics, University of St Andrews, Scotland, UK, and Professor of Neurodevelopment Genomics, University of Bonn, Germany"This book offers an elegant and accessible roadmap to psychobiology, combining foundational neuroscience, core theories, and contemporary applications – such as climate psychobiology and artificial intelligence integration in psychobiology – in a way that is both rigorous and highly readable. It is ideally suited for undergraduate students looking for a first, inspiring encounter with the biological bases of behaviour.”Marietta Papadatou-Pastou, DPhil, Associate Professor of Neuropsychology, National and Kapodistrian University of Athens, Greece
