Discusses the structures that make up the outer and middle ear and the processes by which mechanical vibrations from incoming sound are decoded in the inner ear and understood in the brain. Pines, M., ed. Seeing, Hearing, and Smelling the World . Howard Hughes Medical Institute, 1995. This HHMI report focuses on how the senses work and on current research to extend the frontiers of our understanding of the neurosciences that underlie the senses.
Visual awareness involves more than just what our retinas register.
Just how the brain selects and alters visual signals is a momentous issue in neuroscience being addressed through study of the visual systems of man and monkeys. Scientists have identified a gene that is somehow responsible for higher mental processes, particularly the ability to break a problem into pieces and then reassemble it. Carr, C., and M. Konishi. Axonal delay lines for tTime measurement in the owl's brainstem. Determining the source of sound is based on anatomical and physiological evidence of unequal delays to a stimulus being transmitted from each ear to the sound-detection portion of the brain.
