Medial temporal lobe

The hippocampus is also useful in the familiarity vs. recollection distinction in recognition as mentioned above. A familiar memory is a context-free memory in which the person has a feeling of "know", as in, "I know I put my car keys here somewhere". It can sometimes be likened to a tip of the tongue feeling. Recollection, on the other hand, is a much more specific, deliberate, and conscious process. The hippocampus is believed heavily involved in recollection, whereas familiarity is attributed to the perirhinal cortex and broader temporal cortex in general; however, there is debate over the validity of these neural substrates and even the familiarity/recollection separation itself.
