these results indicate that (1) short-term memory for spatial information is independent of nmda receptors; (2) the rapid consolidation of spatial information into long-term memory requires activation of hippocampal nmda receptors; (3) nmda receptors are not involved in memory retrieval; and (4) the delay-related effects of nmda receptor antagonists on performance of this task cannot be explained in terms of sensorimotor disturbances. |

accumulating empirical findings about place-memory in humans, nonhuman mammals, and birds suggest it might be productive to reevaluate this theoretical issue with respect to present knowledge about the roles of the hippocampus and other brain structures in declarative memory and in procedural or implicit memory, while considering the hypothesis that some forms of information may exploit long-term memory in parallel with working memory. |

analysis of dissociated states induced by pharmacological influences has led us to the following conclusions: 1) the reversible failures of the retrieval processes are usual for the attention-dependent form of long-term memory, 2) hippocampus is the key structure in brain mechanisms that realize the engram selection during memory retrieval, 3) the central cholinergic and gabaergic systems regulate the retrieval of information, 4) steady disturbances of retrieval of the long-term attention-dependent memory are accompanied by strongly pronounced changes in hippocampal cells including those at the membrane and genomic levels. |
