SP injections in preBötC-surface slices. (A) Lesioned preBötC-surface slice without SP injection. (B) Unlesioned preBötC-surface slice injected with a bolus of SP. (C) Lesioned preBötC-surface slice shown in the acquisition phase (Left) and 3.5 h later during the postlesion epoch (Right). (D) Rn binned in 0.5-min increments for unlesioned preBötC-surface slices (Left; n = 4) and lesioned preBötC-surface slices (Right; n = 5) after SP injection at t = 0. Values approaching one are increasing in regularity whereas values greater than or less than unity are becoming more irregular.
