Containing an astonishing 100 billion nerve cells and transmitting information in just a thousandth of a second, the human brain is the most powerful and mysterious organ in the body. Yet despite decades of research and experimentation, only recently have we been able to unlock the secrets of its complex inner workings and how it governs our thoughts, actions, memories - even our sense of self. In this fascinating exploration of the brain, neurobiologist Moheb Costandi examines both its biology and its influence on our behaviour. Through 50 clear and concise chapters, he draws on many of the most intriguing findings at the forefront of neuroscience: Are male and female brains really different? Does emotion have a biological basis? Can we ever see what people are thinking? And can our life experiences affect our brain physically? From the development of the brain as we grow and age, to the building blocks of consciousness; and from mental disorders such as dementia and schizophrenia to how neural tissue can adapt and reconfigure itself in response to trauma, this is a comprehensive introduction to the incredible science of the human brain.
