Students in the physical and life sciences, and in engineering, need to know about the physics and biology of light. Recently, it has become increasingly clear that an understanding of the quantum nature of light is essential, both for the latest imaging technologies and to advance our knowledge of fundamental life processes, such as photosynthesis and human vision. From Photon to Neuron provides undergraduates with an accessible introduction to the physics of light and offers a unified view of a broad range of optical and biological phenomena. Along the way, this richly illustrated textbook builds the necessary background in neuroscience, photochemistry, and other disciplines, bringing students to the latest work in optogenetics, superresolution microscopy, the single-photon response of individual photoreceptor cells, and more.With its integrated approach, From Photon to Neuron can be used as the basis for interdisciplinary courses in physics, biophysics, sensory neuroscience, biophotonics, bioengineering, or nanotechnology. The goal is always for students to gain the fluency needed to derive every result for themselves, so the book includes a wealth of exercises, including many that guide students through computer-based solutions. Supplementary online materials include real experimental data to use with the exercises.Requires only first-year undergraduate physics and the corresponding mathAdvanced chapters also make the book suitable for graduate coursesAn electronic solutions manual is available to adoptersStrong overlap with the goals of the new MCAT2015
