When combined with global inhibition, this forms an attractor with coherent representations of position as stable states. When biased by local view information, this allows the animal to determine its position relative to the goal when it returns to the environment. We call this self-localization. <\/jats:p><jats:p> When an animal traces specific routes within an environment, the weights in the CA3 recurrent collaterals become asymmetric. We show that this stores these routes in the recurrent collaterals. When primed with noise in the absence of sensory input, a coherent representation of position still forms in the CA3 population, but then that representation drifts, retracing a route. <\/jats:p><jats:p> We show that these two mechanisms can coexist and form a basis for memory consolidation, explaining the anterograde and limited retrograde amnesia seen following hippocampal lesions. <\/jats:p>","DOI":"10.1162\/089976698300017908","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T11:57:52Z","timestamp":1027771072000},"page":"73-111","source":"Crossref","is-referenced-by-count":252,"title":["The Role of the Hippocampus in Solving the Morris Water Maze"],"prefix":"10.1162","volume":"10","author":[{"given":"A.
