摘要: A novel somatotopic map of primary cutaneous afferents projecting to the cuneate nucleus in rat was determined by transganglionic transport wheat-germ agglutinin conjugated horseradish peroxidase and free peroxidase. Intracutaneous injections tracer into different limited regions forelimb resulted discrete areas label for each injection site, with little or no overlap other projection areas. The projections onto revealed our anatomical tracing provided much more detail than any previous study rat, demonstrated some significant differences from earlier maps based on electrophysiological recordings.
