Patterns of intersection among climbing fiber receptive fields.
Peripheral receptive fields of climbing fiber responses from the anterior lobe of the cat display large intersections and distinct organizations. Receptive fields of the extremities and face have boundaries that follow the lines of a grid. Receptive fields of the tail and ventral trunk and some of the receptive fields on the extremities form concentric sets, which can be completely ordered by inclusion. Receptive fields along the spine form a chain, which indicates rostrocaudal position. Such regularities among the intersections, especially in the grid organization, allow the receptive fields to encode combinations and alternative combinations of skin locations as a pianist might distinguish chords rather than notes.
