The total or absolute representation of the larynx is indicated by dotting, the depth of the same showing the degree of representation. R. Fissure of .Rolando. Pc. Prsecentral sulcus. F. Focus of highest development of laryngeal representation, i.e., pure intrinsic movement of adduction. v. The small secondary sulcus indicated by that letter. Sy. Fissure of Sylvius. PLATE 32. Fig. 2. Three-quarters view of Cat’s brain, half natural size. c.s. Crucial sulcus. d. Krause’s centre of adduction. d'. Centre of adduction also noted by the authors. b. Focus of abduction. Fig. 3. Base of Cat’s brain, half natural size Fig. 4. Side view of Cat’s brain, natural size ^Lettering as above, fig. 2. Fig, 5. „ ,, half natural size I Fig. G. View of Cat’s brain from above. The right hemisphere has been sliced horizontally, as described in the text, to show the internal capsule. olf Olfactory lobe. p.f. P reef rental fibres. Ca. Caudate nucleus. g. Genu. o.th. Optic thalamus. n.l. Lenticular nucleus (putamen). F.S. Fissure of Sylvius. 1. Anterior limit of fibres excitation of which produces acceleration of respiration. 2.
