Effect of cooling motor cortex on PPCr stimulation-evoked movements in case 13–39. Arm movements evoked by stimulating a site in PPCr (orange circle) were videotaped before, during, and after cooling deactivation of the forelimb lift representation in M1/3a. This figure demonstrates homotopic interactions between M1 and PPCr in which a similar movement evoked in PPCr is abolished. When cortex was returned to normal temperature, the movement returned, the amplitude of the movement was greater, and the end position of the movement was higher than baseline. Conventions are as in previous figures.
