… scientist Richard Semon introduced the concept of the “engram” 115 years ago to posit a neural basis for memory, … with others in other regions, such as the cortex, into an “engram complex.” Crucial to this process of linking engram cells is the ability of neurons to forge new circuit …

… Memory pioneer Richard Semon had predicted such a “unified engram complex” more than a century ago, but achieving the … provides the first rank-ordered list for high-probability engram regions. This list should lead to many future studies, … The team was able to map regions participating in an engram complex by conducting an unbiased analysis of more …

… is stored in a specific pattern of connectivity between engram cell ensembles that lie along an anatomical pathway. … the prefrontal cortex became active, while the hippocampal engram slowly became silent. In their new  PNAS  study, the … in the specific pattern of connections formed between engram cell ensembles. These connections, which form very …

… available, is a change in the electrical excitability of “engram cells,” or the ensemble of neurons that together … showed that after mice formed a memory in a context, the engram cells encoding that memory in a brain region called … a little shock in a specific context one day, then the engram cells would be much more excitable for about an hour …

… brain forms a memory of a new experience, neurons called engram cells encode the details of the memory and are later … formation and recall, and are thus considered to be the engram neurons. Epigenomic control Engram cells are found in the hippocampus as well as other …

… 2012, Tonegawa’s lab developed a way to label cells called engram cells, which  contain specific memories . This allows … found that memories of the event were being stored in engram cells in both the hippocampus and the prefrontal cortex. However, the engram cells in the prefrontal cortex were “silent” — they …
