Thorough, rich of examples, and well planned, which makes it an excellent textbook. It is also written in a plain and engaging way and should appeal easily to undergraduate and master students. Perhaps even more importantly, it pushes the reader to rethink our typical approach to sensory systems, making it an excellent read for anybody interested in Perception. Functions take the lead over receptors, and processing of information takes the lead over neural signals somehow turning over the habitual approach to perception. Underscoring these aspects is not only fun but is also crucial to understand how our mind works. The book makes great strides in this direction.
