In doing so, they identified a molecular mechanism mediated by a specific protein located in the synapse that is involved in regulating the connectivity between engram cells. FromScience Daily Word of the Day March 24, 2025 Start each day with the Word of the Day in your inbox!
Engram cells are often conceived as neurons that (a) are active during initial learning, (b) display some persistent physical change in response to learning, and (c) are reactivated during (and required for) memory retrieval [1,2,8]. According to this strict definition, no new neurons are ...

1. any group of neurons that conduct impulses in a coordinated manner, as the assemblages of brain cells that record a visual stimulus. 2. Also called neu′ral net′. a computer model designed to simulate the behavior of biological neural networks, as in pattern recognition, language processi...
The brain stores and recalls memories through a set of neurons, termed engram cells. However, it is unclear how these cells are organized to constitute a corresponding memory trace. We established a unique imaging system that combines Ca2+ imaging and en
One must demonstrate that these cells are activated by learning, that they undergo enduring physical or chemical changes, and that their reactivation results in recall of the originally formed memory. To design and conduct an experiment that will satisfy all the criteria of the definition at once ...
The set of cells with facilitated synapses is now the anatomical correlate of the memory and is called a memory engram. Once the engram is formed, anything that activates it will revive the original perception as a memory. Now where did I put those keys? Aligned with central theory is the...
Gerber and co-workers83asked whether it is possible to localize a memory trace to a subset of cells in the brain. According to them, it needs to be shown that (1)neuronal plasticityoccurs in the respective cells, (2) neuronal plasticity in these cells is sufficient for memory recall, (3...
