The book progresses logically from the fundamentals of sound and echolocation to the anatomy and physiology of bats' vocal and auditory systems. It then examines the diverse types of echolocation calls and the neural processing that allows bats to interpret echoes. A key focus is the complex neural computations involved in echo processing, offering a deeper understanding of the bat's sensory world compared to simple behavioral descriptions. This unique approach provides new perspectives on sensory processing and could inspire advancements in fields like robotics and assistive technologies.
