III. An experimental investigation into the arrangement of the excitable fibres of the internal capsule of the bonnet monkey (macacus sinicus)

In the following paper we propose to give the results of a research on which we have been engaged nearly three years, and by which we hoped to elucidate the arrangement of the motor fibres in the internal capsule. The fibres which connect the excitable areas in the cortex cerebri with the bulbospinal grey matter in the medulla oblongata and spinal cord are commonly spoken of as forming the pyramidal tract.
