  • Concentrations are expressed as mean percentage ± SEM of the 0 hr − (100%) control mean values. Groups of animals were fully trained (+), entered the training apparatus without receiving foot shock (−), or received the shock without exposure to the apparatus [shock only (SO)] and killed at assigned time points.
