This introduction to neuroscience is unique in its emphasis on how we know what we know about the structure and function of the nervous system. What are the observations and experiments that have taught us about the brain and spinal cord? The book traces our current neuroscientific knowledge to many and varied sources, including ancient observations on the role of the spinal cord in posture and movement, nineteenth-century neuroanatomists' descriptions of the nature of nerve cells, physicians' attempts throughout history to correlate the site of a brain injury with its symptoms, and experiments on the brains of invertebrates. ukryj opis
