Cover picture: Place selectivity of rat hippocampal pyramidal cells during performance of an eight-item spatial sequence task containing a nested repeating segment. A rat was trained to run continuously to a sequence of goals located around the perimeter of a circular table. Gray lines show trajectories for ~100 traversals of the sequence. Multitetrode recording was used to monitor the activity of 57 dorsal CA1 cells. Data shown are from seven pyramidal cells with well defined place fields. Locations where spikes were recorded are shown as colored dots, where each color corresponds to a different cell. Rats learned the sequence task easily, but CA1 cells did not discriminate sequential context when the rat traversed the repeated segments. For details, see the article by Bower et al. in this issue (pages 1313–1323).
