Beside this, what are Engram cells?

Combining this activity-dependent cell labelling with optogenetics led to the discovery of engram cells in the hippocampus; engram cells are defined as neurons that are activated during an experience, that have undergone enduring physical or chemical changes and that can subsequently be selectively reactivated to

Beside above, what is the elusive Engram?

The Elusive Engram: An Experiment in Memory Implantation. In this experiment, Tonegawa's team of neuroscientists were able to implant artificial memories into the brains of mice using optogenetics, a technology in which the activity of specific neurons can be modulated by exposure to certain wavelengths of light.
