Brain takes a 21st Century Look at the major concepts that will help the reader understand the complex structure and function of the brain, whether plants have brains and what the brains of small animals like flies and worms look like and if size matters. Brain looks at the structure of neural cells and what a synapse looks like and does as well as examine the chemical nature of how nerves work and how some molecules like dopamine work to influence the way our nervous systems work. It also looks at how the brain works and what parts of the brain might control what functions and how FMRI (functionalMagnetic Resonance Imaging) looks at the brain. This lavishly illustrated book examines how our brain works when we sleep, see things, perceive and remember things.
