New Advances in Hippocampal Spatiotemporal Coding—Multiplexed Theta Phase Coding and the Regulation by External vs. Self-Motion Cues —Review of the latest Nature Neuroscience paper: “allothetic and idiothetic spatial cues control the multiplexed theta phase coding of place cells” 1. Academic Background & Motivations Spatial navigation and memory ha...

Academic Background The hippocampus is a critical region in the brain responsible for spatial navigation and episodic memory. Pyramidal neurons in the CA1 region of the hippocampus (CA1 pyramidal neurons, CA1PNs) encode an animal’s position in the environment by forming “place fields” (PFs). The formation of place fields relies on behavioral timesc...
