Memory architecture: consolidation and the neurobiology of grief

The article analyzes the dynamic nature of memory, focusing on processes occurring during NREM sleep and quiet wakefulness. A key element is the phenomenon of replay and sharp-wave ripples, which enable the compressed reactivation of experiences in the hippocampus. These processes are not simple data copying, but a complex reorganization of neuronal relationships and communication between the hippocampus and the neocortex. The author emphasizes that memory is not a static warehouse, but a generative system that prioritizes relevant information, strengthens specific connections, and allows for the simulation of future events (preplay). Overall, this sheds new light on the neurobiological foundations of identity and the mechanisms of offline information processing.
