The fifth edition of From Neuron & Brain has been thoroughly rewritten with new chapters added to provide a readable up-to-date book for use in undergraduate graduate & medical school courses in neuroscience As in previous editions the emphasis is on experiments made by electrical recordings molecular & cellular biological techniques & behavioral studies on the nervous system from simple reflexes to cognitive functions Lines of research are followed from the inception of an idea to new findings being made in laboratories & clinics today A major change is that this edition begins with the anatomy & physiology of the visual system from light receptors in the retina to the perception of images This allows the reader to appreciate right away how nerve cells act as the building blocks for perception Detailed mechanisms of signaling are then described in later chapters
