Mouse hibernation triggers major synapse loss but memories stay intact

New research has found that inducing a hibernation-like state in mice leads to a significant reduction in synaptic connections in the brain. Scientists studied the neurological effects of torpor, a deep sleep state similar to hibernation, on the rodents. Despite the substantial loss of synapses, the mice appeared to retain their memories after emerging from the state. The findings raise intriguing questions about how the brain preserves memory even when its physical connections are dramatically reduced. Researchers believe this could have implications for understanding memory storage and potentially treating neurological conditions.
