“…We have only begun to empirically investigate this question.We suspect that spatial pattern learning involves movement-generated information as the rat travels among the locations (poles) in the apparatus. Information about the spatial relations among visited poles could be generated by the process of dead reckoning (or path integration; see Biegler, 2000, andGallistel, 1990, for reviews). Information about the spatial relations among baited poles (possibly also between baited and unbaited poles; see DiGello et al, in press) could then result in the development of a representation of the spatial pattern.…”

Two experiments were conducted to examine the effects of redundant and relevant visual cues on spatial pattern learning. Rats searched for hidden food items on the tops of poles that formed a square (Experiment 1) or a checkerboard (Experiment 2) pattern. The experimental groups were trained with visual cues that specified the locations of the baited poles. All groups were tested without visual cues so that any overshadowing or facilitation of spatial pattern learning by visual cues could be detected. Spatial choices were controlled by the spatial pattern and by the visual cues in both experiments. However, there was no evidence of overshadowing or facilitation of spatial pattern learning by visual cues in either experiment. The results are consistent with the idea that the representation of the spatial pattern that guides choices is not controlled by the same learning processes as those that produce associations between visual cues and food locations.

“…Experiments in compartmentalized mazes suggest that grid maps anchor at many locations and often near salient environmental features 32 . Frequent anchoring may prevent drift due to accumulation of path-integration error 39 . The frequency at which grid maps are updated is not known, however.…”

One of the grand challenges in neuroscience is to comprehend neural computation in the association cortices, the parts of the cortex that have shown the largest expansion and differentiation during mammalian evolution and that are thought to contribute so profoundly to the emergence of advanced cognition in humans. In this review, we will use grid cells in the medial entorhinal cortex as a gateway to understanding network computation at a stage of cortical processing where firing patterns are shaped not primarily by incoming sensory signals but to a large extent by intrinsic properties of the local circuit.

“…This navigational feat is accomplished with remarkable precision by a path integrator, which allows for an approximate form of dead reckoning (Wehner and Wehner, 1986;Wehner and Wehner, 1990;Müller and Wehner, 1988;Wehner and Labhart, 2006). To perform path integration the animals need two types of essential information, that is, directional information (with reference to an external compass cue), and information about the distances travelled in a particular direction [(Müller and Wehner, 1988;Wehner, 1994); for a discussion of the necessity of distance information, however (see Biegler, 2000)]. It is well established that ants as well as other insects rely on polarizational (and, to a lesser degree, on intensity and spectral) sky-light cues, for determining their travelling direction (e.g.…”

maze was covered by orange Perspex that did not transmit the UV part of the spectrum, and thus precluded the perception of polarization patterns. Changes of the ant's processing of odometric information within this channel segment directly translate into a change in homing direction on the test field. The results indicate that the odometric information about travelling distance is largely ignored for path integration if there is no simultaneous input from the sky-view-based compass. They further show that idiothetic information cannot adequately substitute for the polarization compass to infer travelling directions.
