Sleep not only consolidates memories but also resets the brain’s memory storage mechanism. This process, governed by specific regions in the hippocampus, allows neurons to prepare for new learning without being overwhelmed, opening potential pathways for enhancing memory and treating neurological disorders.
A new study reveals the role of the molecule KIBRA in forming long-term memories. Researchers found that KIBRA acts as a “glue,” binding with the enzyme PKMzeta to strengthen and stabilize synapses, crucial for memory retention.
A detailed map of the cells and synapses in a segment of a human brain sample has been created through a collaboration between Harvard and Google. The ultimate goal is to create a full map of a human brain like this, with each synapse and other structures detailed.
