How the Brain Uses Place Cells to Anchor Episodic Memories

Researchers have developed a model explaining how place cells in the hippocampus anchor both spatial and episodic memories. Grid cells in the entorhinal cortex interact with hippocampal cells to create a scaffold, linking memories to specific neural patterns.

How Sleep Shapes Our Brain’s Mental Navigational Maps

A new study reveals how the brain forms cohesive mental maps of spaces and highlights the critical role of sleep in this process. While "place cells" in the hippocampus mark specific locations, weaker spatial cells stitch these points into a comprehensive cognitive map.

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.

First Glimpse of Brains Retrieving Mistaken Memories Observed

Rat study reveals place cells in the hippocampus have the same patterns of activity whether they correctly, or incorrectly recall a memory. However, when the memory is incorrect, the activity begins later and is slower.
