Examples of restraint tubes used in this study. On the left, a rat is shown in the restraint tube used in previous studies which holds the head almost completely immobile within a plug at the rostral end of the tube. On the right, a rat is shown in the restraint tube with a yoke that constrained body movements but allowed relatively free movement of the head and neck.
