Example from one session of changes in the pattern of hippocampal activity within a trial. The top row of graphs show the 1st, 3rd and 5th events on trial 15 of this session. Because the rat alternated sides of the testing enclosure, these events all occurred on the left side of the enclosure. The bottom row shows the 1st, 3rd, and 5th events on trial 16 of the same session. These events all occurred on the right side of the enclosure, and the difference in pattern of activity between the top row and bottom row illustrates the influence of location on the hippocampal ensemble response. The difference between events within a trial illustrates the effect of temporal context on the hippocampal ensemble, and the numbers above the double arrows show the Distance Indices for the indicated comparison.
