Summary: A new study identifies neurons in the hippocampus that store food-specific memories, directly influencing overeating and body weight. These neurons, which encode memories for sugar and fat, act as “memory traces” that drive dietary behavior and metabolism. Silencing these neurons in mice disrupted sugar-related memories, reduced intake, and prevented...

Summary: Researchers have developed a model explaining how place cells in the hippocampus anchor both spatial and episodic memories. Grid cells in the entorhinal cortex interact with hippocampal cells to create a scaffold, linking memories to specific neural patterns.This model mirrors biological memory systems, addressing phenomena like gradual memory degradation...
