What are emotions and why are they needed? For centuries of studying this question, scientists have not found an answer to it. Moreover, they can't even agree on what this answer should look like. Neuroscientist David Anderson is convinced that neuroscience can offer an objective and empirical approach to the study of emotions. It allows you to search for answers to those questions about emotions that were previously considered unsolvable. For many years, Anderson has been studying the neural systems that control emotional behavior in animals in order to understand similar brain mechanisms in humans. The results obtained by the scientist are of great scientific importance. They allow us to draw crucial conclusions about the emotional behavior of animals and humans and promise a real breakthrough in the treatment of mental illness. Unfortunately, not a single fundamentally new drug for the treatment of mental illness has been approved in the last 50 years. All the so-called new drugs are of the same type. Talking about his approach to the study of emotions, Anderson acts not only as a theorist, but also as a practitioner, offering useful strategies for improving emotional intelligence and reducing stress associated with emotions. Unlike fading away, which usually reflects a state of fear, aggressiveness can be associated with different motivations: for example, it can be a response to a threat or a desire to establish dominance. The book is aimed at psychologists, neuroscientists, as well as anyone who wants to learn how to manage the emotional sphere. For example, if you drink several cups of coffee, then due to the stimulating effect of caffeine, you will jump in response to an unexpected sound, to which you would have previously only turned your head or not reacted at all.
