Memory may not work how we thought, study of mice in artificial hibernation finds

The study revealed that mice can retain memories even after losing more than half of their hippocampal synapses. This discovery contradicts the prevailing theory that memories are stored in the brain through synaptic connections. The study was conducted by inducing artificial hibernation in mice, during which a significant portion of their hippocampal synapses were lost.

Despite this loss, the mice were able to recall memories, suggesting that memory storage may not rely solely on synaptic connections. This finding has sparked interest in the scientific community, with outlets like New Scientist describing the discovery as 'remarkable'. The research indicates that memory storage mechanisms in the brain may be more complex than previously understood.

The study's implications extend beyond mice, raising questions about how human memory functions. Researchers are now exploring whether similar mechanisms exist in humans, and if so, how they might be harnessed to improve memory retention and treatment of memory-related disorders.
