Assessing spatial learning and memory in rodents.
Maneuvering safely through the environment is central to survival of almost all species. The ability to do this depends on learning and remembering locations. This capacity is encoded in the brain by two systems: one using cues outside the organism (distal cues), allocentric navigation, and one using self-movement, internal cues and nearby proximal cues, egocentric navigation. Allocentric navig...
متن کاملMelatonin improves spatial navigation memory in male diabetic rats
The aim of the present study was to evaluate the effect of melatonin as an antioxidant on spatial navigation memory in male diabetic rats. Thirty-two male white Wistar rats weighing 200 ± 20 g were divided into four groups, randomly: control, melatonin, diabetic and melatonin-treated diabetic. Experimental diabetes was induced by intraperitoneal injection of 50 mg kg-1 streptozotocin. Melatonin...
متن کاملLatent inhibition in a navigation task: Evidence for the use of associative processes in spatial memory
Rats were trained to find an invisible platform in a Morris water maze. One group was preexposed to the landmarks that subsequently defined the location of the platform while the control group was preexposed to the apparatus, without landmarks. Preexposed rats showed a retarded learning when swimming to the platform. These results provide little support for the notion of a cognitive map and are...

متن کاملSpatial Memory in Insect Navigation
A wide variety of insects use spatial memories in behaviours like holding a position in air or flowing water, in returning to a place of safety, and in foraging. The Hymenoptera, in particular, have evolved life-histories requiring reliable spatial memories to support the task of provisioning their young. Behavioural experiments, primarily on social bees and ants, reveal the mechanisms by which...
