- W4387459712 abstract "Classic findings of impaired allocentric (observer-independent) spatial learning and memory in individuals with lesions to the hippocampus provide strong support for the long-held view that the hippocampus is necessary for supporting a cognitive map of one’s environment. Most of these studies assess navigation in vista-space virtual reality (VR) environments and compare the performance of amnesic individuals to that of small control samples, potentially stifling the ability to detect areas of preserved and impaired performance. Using the mobile app Sea Hero Quest, the current study examines navigation in diverse complex environments in two well-characterized individuals with bilateral hippocampal lesions in comparison to age-, gender-, and geographic-matched control participants (N = 17,734, subsampled from 4 million participants). We found surprisingly accurate navigation in several environments tested, particularly those environments that contained few sub-goals or that could be solved by holding in mind a set of turns along a constrained set of paths. These findings are consistent with the view that the hippocampus plays a critical role in supporting spatial memory and navigation when flexible, detailed representations are concerned and there is a greater demand on memory abilities. Study results emphasize the value of combining single case and big data approaches, helping to refine theories of hippocampal function and predict areas of preservation and deficit in the many individuals afflicted with hippocampal compromise." @default.
