Preview

Rats may use at least two navigational strategies that aid in the recovery of resources and protection from predation: allothetic and idiothetic. Allothetic navigation involves the use of external cues (visual, auditory, or olfactory cues). Idiothetic navigation involves the use of uses cues generated by self-movement (proprioceptive and vestibular cues, sensory flow, or efferent copies of movement commands). A prominent form of idiothetic navigation is dead reckoning, in which a rat locates its present position in relation to a starting position, to which it can return. This chapter presents behavioral techniques used to investigate dead reckoning and describes a theoretical framework for dead reckoning.
