Much evidence indicates that recognition memory involves two separable processes, recollection and familiarity discrimination: indeed it is not uncommon to recognize a person as familiar and not being able to recall identity of this person. It has been recently established that the familiarity discrimination is dependent on a small network of neurons located in a part of the brain called: perirhinal cortex. Our research investgates how this small cortical network underlies amazing capabilities of human recognition memory.
