Researchers from ISTA and Max Planck Institute have uncovered new details about molecular mechanisms driving memory processing at mossy fiber synapses in the hippocampus, crucial for memory formation.
The hippocampus is known to convert short-term memory into long-term memory. The study sheds light on how structural and functional changes in mossy fiber synapses may facilitate the encoding and storage of memories in the hippocampus.
The new research focuses on the mossy fiber synapse, a key connection point between neurons in the hippocampus. The scientists used a novel technique called "Flash and Freeze" combined with freeze fracture labeling to study the dynamic changes in proteins Cav2.1 calcium channels and Munc13 during signal processing. They found that upon stimulation, these proteins rearranged and moved closer together, enhancing neurotransmitter release and potentially contributing to memory formation.

A unique resource for hippocampus researchers and learners, offering tools to build and explore models of the hippocampus and its components using powerful modeling workflows.
