text: **Figure 2.**A depiction of the T-maze. (**A**) The full layout of the T-maze task, with the centre location, 
  the cue location and the two reward conditions. (**B**) A three-step example of a T-maze trial. The agent 
  (in this case, a mouse) starts at the centre location. In order to reduce the uncertainty regarding which 
  arm the reward is located in, the agent moves to the cue location. The cue location reveals the right 
  arm to be the reward location, and in the subsequent time step, it goes to the right arm and observes 
  the reward with some probability.
