摘要: Abstract The motor activity of mice in tests “exploration” is organized. Mice establish home bases, operationally defined as places where they spend long periods time, near physical objects and nesting material from which make excursions. This organization raises the question extent to mouse motoric modulated by innate predispositions versus environmental influences. Here influence contextual cues (visual tactile) on C57BL/6 was examined: (1) an open field that had no walls, a partial wall, or complete (2) presence distinct visual cues, room absence (infrared light), (3) configurations tactile cues. were generally less active salient formed bases those In addition, movement speed, path distribution, number length stops With repeated tests, favored over their base locations. Although responses robust test days, conditioning context weak. That exploratory behavior affected experience provides insights into performance variability may prove useful investigating genetic neural influences behavior.
