News Finding: Then the team ran the experiment again - but only after training the rats to sometimes associate a particular spot in the environment with a large food reward.That training seemingly altered the firing pattern of the rats' grid cells: The neurons fired closer to the reward location, shrinking the spacing of the navigational grid around that position like water swirling down a drain.
Paper Finding: One-sided t test regression analysis: MEC, r = 0.1181, P < 0.00001; CA1, r = -0.00227, P = 1.
News Context: There, for instance, they might use information from previous experiences to guide their search. Then the team ran the experiment again - but only after training the rats to sometimes associate a particular spot in the environment with a large food reward.That training seemingly altered the firing pattern of the rats' grid cells: The neurons fired closer to the reward location, shrinking the spacing of the navigational grid around that position like water swirling down a drain. The overall orientation, or tilt, of the grid also rotated, as if responding to an entirely different spatial context.
Paper Context: Finally, we showed that assembly expression of different goal-related context rapidly alternated in MEC during learning, similar to CA1 flickering (19, 20) . One-sided t test regression analysis: MEC, r = 0.1181, P < 0.00001; CA1, r = -0.00227, P = 1. Spearman correlation analysis: MEC, r = 0.10415, P < 0.00001; CA1, r = -0.02331, P = 0.02369.
