Piloting

摘要: Allothetic navigation involves the use of external cues (visual, auditory, or olfactory cues). The purpose of this chapter is to describe allothetic navigation and the methods for studying allothetic navigation in the laboratory. Because a remarkable array of tasks have been developed, this chapter reviews only those tasks that have received widespread use and are important for understanding the theoretical basis of allothetic navigation. These tasks include the T-maze, the cross-maze, the radial arm maze, the place preference task, the Morris water task, and the exploration task. The taxon system, based on stimulus-response associations, and the locale system, based on spatial relationships in the form of a cognitive map enable the rats to use different navigation strategies. These strategies include cue navigation, guidance, route, and place navigation strategies. The brain substrates of navigation in rats are also …
