From fine-scale foraging to broad-scale migration, animal movement is shaped by the distribution of resources. There is mounting evidence, however, that learning and memory also guide movement. Although migratory mammals commonly track resource waves, how resource tracking and memory guide long-distance migration has not been reconciled. We examined these hypotheses using movement data from four populations of migratory mule deer (n = 91). Spatial memory had an extraordinary influence on migration, affecting movement 2-28 times more strongly than tracking spring green-up or autumn snow depth. Importantly, with only an ability to track resources, simulated deer were unable to recreate empirical migratory routes. In contrast, simulated deer with memory of empirical routes used those routes and obtained higher foraging benefits. For migratory terrestrial mammals, spatial memory provides knowledge of where seasonal ranges and migratory routes exist, whereas resource tracking determines when to beneficially move within those areas.

According to some theoretical models, information contained in visual short-term memory (VSTM) consists of two main memory stages/storages: sensory memory, a system wherein information is stored for a...
Ample evidence suggests that there is overlap between the eye-movement system and spatial working memory. Such overlapping structures or capacities may result in interference on the one hand and benef...
Visual attention, visual working memory, and gaze control are basic functions that all select a subset of visual input to guide immediate or subsequent behavior. In this review, we focus on the relati...
Acute stress leads to a rapid release of noradrenaline and glucocorticoids, which in turn influence cognitive functions such as spatial learning and memory. However, few studies have investigated nora...

Memory related to spatial information.
Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.
Measures of spatial cognition and memory.
Type of declarative memory, consisting of personal memory in contrast to general knowledge.
Neurons in the ENTORHINAL CORTEX that project to the HIPPOCAMPUS. Grid cells and PLACE CELLS play a role in cognitive representation of spatial memory and navigation.
