Document Summary

The longer the memory has been consolidated for the stronger it is and the less susceptible to damage it is. Note: systems consolidation (years) is different than synaptic consolidation (hours: 15 years is long enough for systems consolidation** Still activation of the hippocampus when recalling early memories.

Traces determine the contents of our ltm: each reactivation of an experience (bringing up a memory), creates a new trace of that information in the brain and areas of the cortex mtl.
