abstract：:Intracellular recording techniques were used to test for cross-modality and topographic convergence among inputs to area 3a of cerebral cortex. Recordings were made within the projection area of group I afferent fibers of the deep radial nerve in barbiturate-anesthetized cats. Epsps were evoked in 90% of neurons (81/9...
