Episodic memory, amnesia, and the hippocampal–anterior thalamic axis
By utilizing new information from both clinical and experimental studies with animals, the anatomy underlying anterograde amnesia has been reformulated and places critical importance on the efferents from the hippocampus via the fornix to the diencephalon.
Recognition memory: What are the roles of the perirhinal cortex and hippocampus?
This work focuses on the central issue in this dispute — the relative contributions of the hippocampus and the perirhinal cortex to recognition memory.
What does the retrosplenial cortex do?
Advances on multiple fronts that have highlighted the importance of the retrosplenial cortex for cognition are reviewed, and why specifying its precise functions remains problematic are considered.
Extending the spontaneous preference test of recognition: evidence of object-location and object-context recognition
The results showed that rats were sensitive to the changes made in all of the test conditions and that the level of discrimination varied within the 3 min test phase, and the first 2 min were found to be the most sensitive period.
Spontaneous object recognition and object location memory in rats: the effects of lesions in the cingulate cortices, the medial prefrontal cortex, the cingulum bundle and the fornix
Comparisons with sham-operated control rats showed that none of the four groups (Cg, Fx, CB, Pfc) was impaired on the object recognition task, adding further weight to the view that these structures are not necessary for assessing stimulus familiarity.
Hippocampal–anterior thalamic pathways for memory: uncovering a network of direct and indirect actions
This review charts recent advances from a variety of disciplines that create a new perspective on why the multiple hippocampal–anterior thalamic interconnections are together vital for human episodic
Impaired auditory recognition of fear and anger following bilateral amygdala lesions
A further investigation is reported of one of these rare cases, a woman who has impaired perception of the intonation patterns that are essential to the perception of vocal affect, despite normal hearing, which shows that the amygdala's role in the recognition of certain emotions is not confined to vision, which is consistent with its being involved in the appraisal of danger and the emotion of fear.
Different Contributions of the Hippocampus and Perirhinal Cortex to Recognition Memory
The results establish that the regions of the rat brain associated with discriminating the novelty or familiarity of an individual item differ from those responding to a spatial array of items (such as a scene).

Interleaving brain systems for episodic and recognition memory
New findings that have resulted from improved resolution of functional brain imaging, together with recent studies of amnesia and developments in animal testing, reinforce the view that recognition memory comprises at least two independent processes: one recollective and the other using familiarity detection.
