The Role of Cells in Encoding and Storing Information: A Narrative Review of Cellular Memory.
Cureus November 1, 2024 Ana I Flores, Mitchell B Liester 2 citations
Memory involves encoding, storing, and retrieving information, and recent research suggests it extends beyond the brain to include body-based and cellular mechanisms. Synaptic changes in the hippocampus are crucial for memory consolidation, but somatic memory shows how sensory and traumatic experiences are stored implicitly. Studies indicate that memories can be encoded and stored in cells and may be transferred between individuals through organ transplantation. Observations in organisms without nervous systems, such as bacteria, fungi, and plants, expand traditional memory concepts. This review compiles findings across disciplines to build a framework explaining cellular processes in memory retention and transfer, though critical gaps remain in understanding how cellular memory interfaces with neural systems.
