One traditional and long-held view of medial temporal lobe (MTL) function is that it contains a system of structures that are exclusively involved in memory, and that the extent of memory loss following MTL damage is simply related to the amount of MTL damage sustained. Indeed, human patients with extensive MTL damage are typically profoundly amnesic whereas patients with less extensive brain lesions centred upon the hippocampus typically exhibit only moderately severe anterograde amnesia…

TLDR
Evidence is provided that despite the strong connectivity between these cortical regions and the hippocampus, the hippocampus has a distinct function of its own—combining information about objects, positions, and contexts.
The Contribution of the Human Medial Temporal Lobe to Perception: Bridging the Gap between Animal and Human Studies
TLDR
The current article reviews the human neuropsychological literature to determine whether there is any evidence to suggest that the medial temporal lobe may be critical to higher order perceptual processes, with the hippocampus and perirhinal cortex being involved in scene and object perception, respectively.

TLDR
A new view of perirhinal cortex function is proposed, one that does not assume strict modularity of function in the occipito-temporal visual stream, but replaces this idea with the notion of a hierarchical representational continuum.
Recognition memory: Material, processes, and substrates
TLDR
Overall, it is concluded that most, though not all, of the recent findings are in support of the proposal that a system centering on the perirhinal cortex is responsible for familiarity discrimination, particularly for single items, although there remain examples of the independent operation of the hippocampal and perIRhinal systems.
Episodic memory in aspects of large-scale brain networks
TLDR
This review focuses on the functional organization of the MTL and other neocortical areas in episodic memory and shows that brain stimulation may impact memory through modulating functional networks, carrying future implications of a novel interventional therapy for memory impairment.

Selective hippocampal lesions yield nonspatial memory impairments in rhesus monkeys
TLDR
The effects of excitotoxic lesions of one of the MTL structures, the hippocampus, on the rate of learning of discrimination problems embedded within unique contexts strongly support the idea that the difference in the effect on object memory of MTL damage in human and nonhuman primates is due to a difference to the opportunity to employ contextual cues rather than to a change in the organization of memory.
Severity of memory impairment in monkeys as a function of locus and extent of damage within the medial temporal lobe memory system
TLDR
It is suggested that, whereas damage to the hippocampal region produces measurable memory impairment, a substantial part of the severe memory impairment produced by large medial temporal lobe lesions in humans and monkeys can be attributed to damage to entorhinal, perirHinal, and parahippocampal cortices adjacent to the hippocampusal region.

Memory in monkeys severely impaired by combined but not by separate removal of amygdala and hippocampus
TLDR
A discrepancy between the clinical and animal literature could indicate a true evolutionary shift in the functions of the hippocampus, or, at the other extreme, it could simply reflect the use of incommensurate measures across species.
The human perirhinal cortex and recognition memory
TLDR
The findings suggest that the perirhinal cortex is not important for visual perception or immediate memory, and resemble the findings for other medial temporal lobe structures, including the hippocampus.
Hippocampal formation lesions produce memory impairment in the rhesus monkey
TLDR
It is demonstrated that selective damage to the HF is sufficient to produce impairments on tasks involving delayed recognition and memory load, illustrating the importance of the HF in the acquisition and retention of new information.
Lesions of the perirhinal and parahippocampal cortices in the monkey produce long-lasting memory impairment in the visual and tactual modalities
Compared to normal animals, monkeys with bilateral lesions of the perirhinal and parahippocampal cortices (PRPH lesion) were impaired on both a visual and a tactual version of the delayed nonmatching
Human amnesia and the medial temporal region: enduring memory impairment following a bilateral lesion limited to field CA1 of the hippocampus
TLDR
This is the first reported case of amnesia following a lesion limited to the hippocampus in which extensive neuropsychological and neuropathological analyses have been carried out.

TLDR
The discovery that medial temporal lobe lesions produce amnesia in humans if the lesion extends sufficiently far posteriorly to include the hippocampus forms the keystone of the hippocampal memory hypothesis, which concludes that the animal model is a poor one.
