UPenn study rejects hypothesis that the hippocampus exclusively supports the recollection component of recognition memory and, instead, indicates that this structure is functionally relevant to both processes thought to support recognition.

& RECOGNITION
MEMORY
PRESENTATION BY RAGHAV MATTAY
BASED ON RESEARCH BY

2. Hippocampus
the center of emotion as well as integral part of
memory and spatial navigation

3. The Question?
Which of the two processes of recognition memory -
recollection and familiarity - does the hippocampus
support?

4. •
The Study
66 subjects
2 Tests:
participants shown a series of
words, asked to recollect them
participants shown another
series of words (old & new),
asked to decide whether or not
each word was one they were
shown before
•

5. Less high frequency when the participants failed to recognize
a word they had been shown before, or whenever they saw a
new word - whether or not they correctly identified it as new
Results
Noticeably higher frequencies of activity when participants
correctly identified a word they had seen before

6. "Our findings reject the
hypothesis that the hippocampus
exclusively supports the
recollection component of
recognition memory and, instead,
indicate that this structure is
functionally relevant to both
processes thought to support
recognition."
