Consolidating memories

Rated 3.96/5 based on 630 customer reviews

Consolidation represents the processes by which a memory becomes stable.

Recall refers to the ability to access the information (whether consciously or unconsciously) after it has been stored.

Lesions in the medial temporal lobe typically produce amnesia characterized by the disproportionate loss of recently acquired memories.“Episodic learning” — memories that are stored after only one occurrence — might be mainly stored in the hippocampus.This may help explain the persistence of some vivid memories in the hippocampus. My own feeling is that, no, memories don't reach this fabled "cast in stone" state.It has been assumed that once this occurs, the memory is "fixed" — a permanent, unchanging, representation.With new techniques, it has indeed become possible to observe these changes (you can see videos here).
