Reference and workingmemory of ratsfollowing hippocampal damage induced by transientforebrain ischemia. PHYSIOL BEHAV 37(3) 387-392, 1986.--Acquisition of reference and working memory was evaluated in an animal model of cerebral ischemia. Rats were subjected to 30 minutes of transient forebrain ischemia, allowed to recover, and then tested for 95 trials on an 8-arm maze with 5 arms baited. During the 95 trials post ischemic (PI) rats made significantly more working and reference errors than controls (.o0.8). P1 rats tended to have a persistent working memory deficit compared to controls (p 0 . 5 , and noncriterion shams showed no hippocampal pathology. The mean number of reference errors and working errors in blocks of 5 trials are shown in Fig. 3 and Fig. 4, respectively. Control rats (combined control and noncriterion shams, N = 19) and PI rats ( N = 10) demonstrated improved reference performance over trials, F(14,378)=17.70, p
