Researchers have long known that memory is represented by changes in the part of the brain called the hippocampus.
One of the well-established changes in the hippocampus that has been associated with memory is the presence of so-called sharp wave ripples (SWR). These are brief, high-frequency electrical events generated in the hippocampus, and they are believed to represent a major event occurring in the brain in the so-called episodic memory. This type of memory refers to episodes that took place in the life of an individual, such as childhood memories, recollection of the first date with a partner or memory of an old cell phone number.
However, what happens in the famous seahorse-shaped structures of the brain – the hippocampus – when SRWs are generated has not been well understood.
Now a new study sheds light on the existence of a neuron type in the mouse hippocampus that might be…
