Figure 5. Spatial learning in WT and TgF344-AD rats. Female and male wild type (WT) and Tg433-AD (Tg) rats on a control diet (CD) were trained in the Barnes maze test at 8 or 12 (A–D, n = 14–15/group) months of age and latency to escape over trials reported. Spatial learning (latency to escape over trials) was determined in TgF344-AD rats fed a control (CD), intermittent ketogenic (IKD) and ketogenic (KD) at 8 or 12 (E–H, n = 14–15/group) months of age.
