Figure 5. VTE behaviours.

When rats come to difficult choices, they sometimes pause and re-orient back and forth before making their decision. This behaviour, termed VTE, is indicative of indecision and the flexible decision-processes necessary to accommodate it⁵⁰. VTE can be quantitatively measured with the Z-scored integrated absolute angular velocity through the choice point (zIdPhi, see Methods). (a) VTE is significantly increased after the forced strategy-switch on the MT-LRA task. (b) VTE is significantly increased around the moment of behavioural change on the MT-LRA task. (c) VTE is significantly increased before the moment of behavioural change on the DD task.
