Early Experiments on Motor Cortex
This chapter discusses the emergence of dominant ideas about motor cortex. It traces motor cortex research from its beginning to motor maps of Penfield and Boldrey (1937) and Woolsey et al. (1952). This segment of the history is mainly about electrical stimulation applied to the surface of the cortex. Using this technique, researchers drew motor maps of greater and greater elaboration. After Penfield and Woolsey, more fine-grained techniques such as microstimulation and single-neuron recording were used to probe the details and reopened all the same questions and debates.
