Mental navigation in the primate entorhinal cortex.

ABSTRACT: A cognitive map is a suitably structured representation that enables novel computations using previous experience; for example, planning a new route in a familiar space¹. Work in mammals has found direct evidence for such representations in the presence of exogenous sensory inputs in both spatial^2,3 and non-spatial domains^4-10. Here we tested a foundational postulate of the original cognitive map theory^1,11: that cognitive maps support endogenous computations without external input. We recorded from the entorhinal cortex of monkeys in a mental navigation task that required the monkeys to use a joystick to produce one-dimensional vectors between pairs of visual landmarks without seeing the intermediate landmarks. The ability of the monkeys to perf
