Summary:
- Researchers at MIT have discovered a new type of brain cell called a "star-shaped" cell that could be important for human memory.
- These star-shaped cells, also known as astrocytes, are found in the hippocampus, which is the part of the brain responsible for forming new memories.
- The researchers believe that these star-shaped cells may help to strengthen the connections between neurons, which is crucial for the formation and storage of memories.
