Figure 5. Sudden changes in behavior.

(A) An example of a long uninterrupted path through 11 junctions to the water port (drop icon). Blue circles mark control nodes related by symmetry to the water port to assess the frequency of long paths occurring by chance. (B) For one animal (named C1) the cumulative number of rewards (green); of long paths (>6 junctions) to the water port (red); and of similar paths to the three control nodes (blue, divided by 3). All are plotted against the time spent in the maze. Arrowheads indicate the time of sudden changes, obtained from fitting a step function to the rates. (C) Same as B for animal B1. (D) Same as B for animal C9, an example of more continuous learning.

Statistics of sudden changes in behavior. Summary of the steps in the rate of long paths to water detected in 5 of the 10 rewarded animals. Mean and standard deviation of the step time are derived from maximum likelihood fits of a step model to the data.

Figure 5—figure supplement 1.

Sudden changes in behavior for all rewarded animals. For each of the 10 water-deprived animals this shows the cumulative rate of rewards, of long direct paths (>6 steps) to the water port, and of similar paths to three control nodes. Display as in Figure 5; panels B-D of that figure are included again here. Dots are data, lines are fits using a four-parameter sigmoid function for the rate of occurrence of the events.
