Abstract
En 中文
The entorhinal cortex–hippocampal circuit constructs spatial maps from the activity of place and grid cells, which can spontaneously change their tuning even in stable environments. Such map changes are often correlated with shifts in behavior. Spatial maps may inherit biases toward behaviorally relevant stimuli from upstream sensory and velocity circuits, which exhibit behavioral state-dependent activity. Spatial maps dynamically amplify behaviorally relevant spatial features, such as the locations of rewards or conspecifics. Behavioral state-dependent spatial maps might facilitate adaptive, goal-directed behavior.
