How Memories Are Chosen for Preservation

Researchers uncovered how the brain chooses which daily experiences to convert into long-term memories during sleep, pinpointing "sharp wave-ripples" in the hippocampus as the crucial mechanism. This phenomenon suggests that events followed by sharp wave-ripples are more likely to be consolidated into permanent memories.

Endocannabinoids Play Role in Spatial Navigation

Researchers made a new discovery about how we navigate our environments, pinpointing a brain cell mechanism crucial for spatial orientation. This research reveals that place cells in the hippocampus, essential for creating mental maps of our surroundings, activate and release endocannabinoids to communicate position information.
