Pyramidal and non-pyramidal projection from cortical areas 4 and 6 to the red nucleus in the cat.
The pyramidal tract (PT) and the red nucleus (RN) of cats were stimulated electrically to identify by antidromic invasion PT and non-PT neurons projecting from cortical areas 4 and 6 to the RN. A main result was that the input to RN is much stronger from PT neurons than that of non-PT neurons in area 4, and vice versa in area 6.
