Using immersive virtual reality to test allocentric spatial memory impairment following unilateral temporal lobectomy
نویسندگان
چکیده
Immersive virtual reality was used to investigate spatial memory in 17 right and 19 left unilateral temporal lobectomy patients and 18 control subjects. The subjects were administered a task consisting of a virtual room and table with radially arranged ‘shells’ on top. The subjects moved around the table and had to find a blue cube, which was under one of the shells. On subsequent searches, the cube moved to a new location and the subject had to find it whilst avoiding the previous location, and so on until all locations had been used. A selective deficit was observed in the right temporal lobectomy group only, linking allocentric memory to the function of the right hippocampal formation.

Egocentric and allocentric memory as assessed by virtual reality in individuals with amnestic mild cognitive impairment.
Present evidence suggests that medial temporal cortices subserve allocentric representation and memory, whereas egocentric representation and memory also depends on parietal association cortices and the striatum. Virtual reality environments have a major advantage for the assessment of spatial navigation and memory formation, as computer-simulated first-person environments can simulate navigati...

متن کاملUsing virtual reality to characterize episodic memory profiles in amnestic mild cognitive impairment and Alzheimer's disease: influence of active and passive encoding.
Most neuropsychological assessments of episodic memory bear little similarity to the events that patients actually experience as memories in daily life. The first aim of this study was to use a virtual environment to characterize episodic memory profiles in an ecological fashion, which includes memory for central and perceptual details, spatiotemporal contextual elements, and binding. This stud...

The aim of this study was to explore the effects of preoperative and postoperative lateralized mesial temporal damage on three measures of spatial learning: navigation, object location and plan drawing, and to determine the relationship between volumetry of the hippocampus and memory performance. Fifteen patients with well-characterized unilateral hippocampal sclerosis, 15 patients who had unde...
