Hippocampal lesions disrupt navigation based on cognitive maps but not heading vectors
We show that hippocampally damaged rats are able to navigate by means of heading vectors but not cognitive maps. Expand

Double dissociation between hippocampal and prefrontal lesions on an operant delayed matching task and a water maze reference memory task
The hippocampus and prefrontal cortex have both been implicated in various aspects of the acquisition, retention and performance of delayed matching to position (DMTP) tasks in the rat, althoughExpand

Conditioning and contextual retrieval in hippocampal rats.
The role of the hippocampus in associative learning was investigated in 3 experiments with rats as subjects. Hippocampal rats were impaired in the acquisition of conditioned responding both when foodExpand

Interaction between piloting and beacon homing by rats in a swimming pool.
In three experiments, rats in a swimming pool were trained to find a submerged platform with a beacon attached to it. For some rats this beacon unambiguously identified the location of the platform;Expand

Acquired equivalence and distinctiveness of cues: II. Neural manipulations and their implications.
Neural manipulations were used to examine the mechanisms that underlie the acquired equivalence and distinctiveness of cues in rats. Control rats and those with excitotoxic lesions of either theExpand

Identifying cortical inputs to the rat hippocampus that subserve allocentric spatial processes: A simple problem with a complex answer
A consideration of the cortical projections to the hippocampus provides a number of candidate regions that might provide distal sensory information needed for allocentric processing. Prominent amongExpand

Selective cytotoxic lesions of the retrohippocampal region produce a mild deficit in social recognition memory
Abstract. Although a number of studies have implicated the hippocampal formation in social recognition memory in the rat, a recent study in this laboratory has demonstrated that selective cytotoxicExpand

The effects of combined lesions of the subicular complex and the entorhinal cortex on two forms of spatial navigation in the water maze.
The role of the subicular complex and entorhinal cortex (SUB-EC) in spatial learning was examined in 2 water maze experiments. In Experiment 1, rats had to locate a hidden platform that was always aExpand

The role of the hippocampus in mnemonic integration and retrieval: complementary evidence from lesion and inactivation studies
Two forms of account have been proposed for how animals form integrated memories for patterns of stimulation: the elemental account holds that the elements that make up the pattern become directlyExpand

The role of the entorhinal cortex in two forms of spatial learning and memory
Abstract. It is generally acknowledged that the rodent hippocampus plays an important role in spatial learning and memory. The importance of the entorhinal cortex (ERC), an area that is closelyExpand
