In the 25 years since From Neuron to Brain was first published, the authors' aim has remained constant: to describe how nerve cells go about their business of transmitting signals, how the signals are put together, and how, out of this integration, higher functions emerge. The new Fourth Edition, while maintaining this focus, has been completely reformatted and updated. - Intended for use in upper-level undergraduate, graduate, psychology and medical school Neuroscience courses, From Neuron to Brain will be of interest to anyone, with or without a specialized background in biological sciences, who is curious about the workings of the nervous system. It presents a readable and coherent account of how cellular and molecular approaches can provide insights into the workings of the brain.
