Sensory Perception: Use of a Musical Notation

Abstract

RECEPTOR units of the peripheral nervous system are distributed in space either compactly, as in the retina, or diffusely, as in the skin and musculature. From these units, afferent fibres enter, again more or less diffusely, a portion or portions of the central nervous system, and with their terminals define within the tissue a series of more-or-less sharply circumscribed volumes, with varying degrees of overlap, into each of which volumes the primary afferents of a sensory modulus come into contact with neurones of the second order. So far, then, we have a point-to-point or point-to-volume mapping of receptor units into a series of territories within the central nervous system¹.
