Internally Generated Cell Assembly Sequences in the Rat Hippocampus
(Summary) It was long thought that the hippocampus was the seat of spatial navigation. However, newer models suggest that other cognitive processes such as episodic memory and action planning depend on the hippocampus. Further, these models suggest that this activity might be internally organized cell assemblies. To unpack the role of the hippocampus, these neurons predict where and animal is coming from as well as its destination through bursts of activity that resides within theta oscillation. These burst of activity occur when the animal rest and sleep as well, which suggests that hippocampal neurons can be disengaged from external landmarks. However, behavioral experiments
