A living creature’s brain, human consciousness… Despite all the scientific discoveries in this field, there remains a vast number of mysteries—even when it comes to animals. And when it’s about humans, the space for further research is unimaginably wide. Neurobiology is one of the youngest and fastest-developing sciences. In just a few decades, thanks to it, people began to understand how hormones and neurotransmitters work, how to regulate their state and mood through simple body movements and thoughts. Even religious feelings, as it turned out, can be broken down into understandable details. This book is about the brain—mysterious yet knowable—the brains of animals and humans; simple and complex, created by nature and shaped by human hands.
