Head direction cells-neurons that fire only when an animal orients its head in a
certain direction-are found in several different brain areas, with different neurons
selective for different head orientations; they are influenced by landmarks as well as
motor and vestibular information concerning how the head moves through space. These
properties suggest that head direction cells play an important role in determining
orientation in space and in navigation. Moreover, the prominence, strength, and clarity
of head direction signals indicate their importance over the course of evolution and
suggest that they can serve as a vital key for understanding brain function.
This book presents the latest findings on head direction cells in a comprehensive
treatment that will be a valuable reference for students and researchers in the
cognitive sciences, neuroscience, computational science, and robotics.
