content: This book covers a lot of material. The quality varies from chapter to chapter. Figures are sprinkled here and there with very little explanation of what they mean. Additionally, there is not much consistency between figures. This book might be serve as a good companion to a course, but it's virtually useless for self study.My background is engineering and neuroscience, but I still found the math to be poorly explained. If you're trying to learn about biophysics and cellular neurophysiology, pick another book. If you're unfortunate enough to have this book assigned to you for a class, make sure you attend the lectures.The index is also terrible and virtually useless for anything that I've tried to look up. The only good thing about the book is that it references a lot of stuff, so you know where to look.One star is for the breadth of topics covered and one is for the references. The Matisse drawing on the cover is also a nice touch.
