FIGURE 8.
(A) KO rats committed a significantly larger overall number of win-stay errors compared with WT rats but this was primarily due to a difference between the male KO and WT rats during the last testing block (days 21–25). (B) KO rats also committed a significantly larger overall number of lose-stay errors compared with WT rats. (C) The SHRs had significantly more win-stay errors overall, primarily due to a difference from WKY rats during the last testing block (days 21–25). (D) The SHRs committed more lose-stay errors overall and during both the first and last testing block, with the difference from the WKY rats being larger during the latter (days 21–25). DSA, delayed spatial alternation; SHR, spontaneously hypertensive rat; SEM, standard error of the mean; WKY, Wistar-Kyoto
