How does the 20-hour observation of rat hippocampal neuron activity during sleep change our understanding of spatial memory consolidation?

Researchers observed hippocampal neuron activity in rats for 20 hours during sleep, revealing how spatial memory of food locations consolidated. Initially, neuron activity reflected learned patterns; however, this pattern evolved throughout sleep, with some neurons' activity waning while others increased, ultimately improving memory recall upon waking.
