article_snippet: Scientists made Scientists discovery in the brains of mice .
article_snippet: For the first time, conscious memories have been implanted into the minds of mice while conscious memories slept.
article_snippet: Scientists from the Industrial Physics and Chemistry Higher Educational Institution in Paris, France, used the brain's replay process - that of replaying the day's events - to create new memories in the brains of mice, while they slept.
article_snippet: While the mice slept, the mice monitored the creature’s brain activity and when the specific place cell fired, an electrode stimulated the brain areas linked to reward.
article_snippet: When the mice woke up, the mice immediately scurried to the location that was linked to the rewarding feeling, showing that a new pleasant memory of the place had been formed by the scientists.
article_snippet: The feat offers hope that the same technique could one day be used to change human memories, which could help people who replay traumatic events over and over in their minds.
article_snippet: researchers focused on the antero-dorsal thalmic nucleus and postsibiculum regions of the brain.
article_snippet: The recordings were then compared with similar readings made in the same mice while The recordings were awake and navigating in various environments.
article_snippet: The next step will be to monitor other parts of the mouse brain involved in more complex forms of behaviours to see if similar neural activity patterns are at work.
