| When lab rats sleep, their brains revisit the maze they navigated during the day, according to a new study {{U}} (1) {{/U}} yesterday, offering some of the strongest evidence {{U}} (2) {{/U}} that animals do indeed dream.Experiments with sleeping rats found that cells in the animals’ brains fire in a distinctive pattern {{U}} (3) {{/U}} the pattern that occurs when they are {{U}} (4) {{/U}} and trying to learn their way around a maze. Based on the results, the researchers concluded the rats were dreaming about the maze, {{U}} (5) {{/U}} reviewing what they had learned while awake to {{U}} (6) {{/U}} the memories. Researchers have long known that animals go {{U}} (7) {{/U}} the same types of sleep phases that people do, including rapid-eye-movement (REM) sleep, which is when people dream.But {{U}} (8) {{/U}} the occasional twitching, growling or barking that any dog owner has {{U}} (9) {{/U}} in his or her sleeping pet, there’s been {{U}} (10) {{/U}} direct evidence that animals {{U}} (11) {{/U}}. If animals dream, it suggests they might have more {{U}} (12) {{/U}} mental functions than had been {{U}} (13) {{/U}}. "We have as humans felt that this {{U}} (14) {{/U}} of memory—our ability to recall sequences of experiences—was something that was {{U}} (15) {{/U}} human," Wilson saiD、"The fact that we see this in rodents {{U}} (16) {{/U}} suggest they can evaluate their experience in a significant way.Animals may be {{U}} (17) {{/U}} about more than we had previously considereD、" The findings also provide new support for a leading theory for {{U}} (18) {{/U}} humans sleep—to solidify new learning. "People are now really nailing down the fact that the brain during sleep is {{U}} (19) {{/U}} its activity at least for the time immediately before sleep and almost undoubtedly using that review to {{U}} (20) {{/U}} or integrate those memories into more usable forms," said an assistant professor of psychiatry at Harvard Medical School. |
