The image shows that proteins are created at connections between brain cells when a long-term memory is formed. Neuroscientists had suspected as much, but hadn't been able to see it happening until now.
Scientists still want to understand more about how our brains translate memories made on the go into long-term storage. Since synapses are connections between cells, experts think that fortifying these connections, or perhaps even making new ones, helps our minds associate different ideas and form memories of connected events.
Speaking of memories, you remember the time we snuck off and made out in that house that was being built? Yeah, that was really, um -- that wasn't you, was it? Oh synapse!
