Anterograde and retrograde labeling in M1 after BDA injections into PMd (monkey H). (A) Upper, Representative coronal section (a) through the injection site (right). SPS, superior precentral sulcus. Lower, Result of ICMS mapping. In the somatotopic map, the body parts of which movements were evoked by ICMS are indicated as follows: E (e), elbow; L (l), leg; S (s), shoulder; T; trunk; W (w), wrist. The uppercase and lowercase letters represent evoked movements by ICMS with a train of 11 or 44 current pulses, respectively. –, no movement elicited. CS, central sulcus. (B) Representative coronal section showing the laminar organization of anterograde and retrograde labeling in M1. A corresponding Nissl-stained section is shown on the right. (C) Higher-magnification photomicrograph taken from the rectangular area in B. Other conventions and abbreviations are as in Fig. 1.
