Complementary Roles of Hippocampus and Medial Entorhinal Cortex in Episodic Memory

Figure 4

Firing patterns of two representative medial entorhinal neurons that reflect both trial disambiguation and a low degree of spatial specificity. (a). This unit was significantly more active on right-turn trials: significant main effect of segment (𝐹_6,392=11.73; 𝑃<.00001), trial type (𝐹_1,392=7.32; 𝑃<.00071) and interaction (𝐹_6,392=2.22; 𝑃<.04); log-likelihood ratio = 4.62; 𝑝_correct=0.67; 𝑝_chance=0.006. (b). This unit was significantly more active on left-turn trials: significant main effect of segment (𝐹_6,280=3.83; 𝑃<.0011), trial type (𝐹_1,280=4.87; 𝑃<.03) and interaction (𝐹_6,280=1.83; 𝑃<.09); log-likelihood ratio = 1.29; 𝑝_correct=0.71; 𝑝_chance=0.004. Color bars indicate firing rate in Hz.
