“…Later, the recognition of the same place allows to set the PI activity to the previously learned values and thus limits cumulative errors. The proposed mechanism is quite similar to the one proposed by Strosslin et al ( 2005 ). It mainly differs by the way PI PI is taken into account.…”

From grid cells and visual place cells to multimodal place cell: a new robotic architecture

In the present study, a new architecture for the generation of grid cells (GC) was implemented on a real robot. In order to test this model a simple place cell (PC) model merging visual PC activity and GC was developed. GC were first built from a simple “several to one” projection (similar to a modulo operation) performed on a neural field coding for path integration (PI). Robotics experiments raised several practical and theoretical issues. To limit the important angular drift of PI, head direction information was introduced in addition to the robot proprioceptive signal coming from the wheel rotation. Next, a simple associative learning between visual place cells and the neural field coding for the PI has been used to recalibrate the PI and to limit its drift. Finally, the parameters controlling the shape of the PC built from the GC have been studied. Increasing the number of GC obviously improves the shape of the resulting place field. Yet, other parameters such as the discretization factor of PI or the lateral interactions between GC can have an important impact on the place field quality and avoid the need of a very large number of GC. In conclusion, our results show our GC model based on the compression of PI is congruent with neurobiological studies made on rodent. GC firing patterns can be the result of a modulo transformation of PI information. We argue that such a transformation may be a general property of the connectivity from the cortex to the entorhinal cortex. Our model predicts that the effect of similar transformations on other kinds of sensory information (visual, tactile, auditory, etc…) in the entorhinal cortex should be observed. Consequently, a given EC cell should react to non-contiguous input configurations in non-spatial conditions according to the projection from its different inputs.

“…This cognitive map creation most likely maximized the ray's survival in the tank's spatially limited environment. Location sensitivity and spatial map formation is a typical hippocampal function in mammals [Bingman et al, 2003;Stro¨sslin et al, 2005]. These trials, therefore, suggest conducting spatial orientation experiments on rays from this taxon.…”

This study reports on the first experimental research designed specifically for Manta birostris behavior. The authors attempted to learn about the feeding behavior and environmental cues influencing this behavior, as well as general cognitive ability. The preconditioned Manta's ability to identify food, on the basis of a fraction of the ordinary food signal complex, was tested. The opening of cephalic fins was considered a good indicator of feeding motivation level. The study subject animal used its biological clock to predict time and also associated a specific location with food, suggesting an ability to build up a cognitive map of its environment. Both underwater visual stimuli and olfactory stimuli had a very intense effect on food searching behavior over a 30 m distance, in contrast to visual signs from above the water surface. In addition, although an underwater visual signal resulted in a more intense response than from an olfactory signal, the specimen did not discriminate between different objects tested on the basis of visual sensation. It could therefore be suggested that food searching behavior of Mantas are governed by triggering stimuli, including smell or visual recognition, and modulated by the cognitive spatial map stored in their long-term memory. These findings will hopefully prove useful while devising protecting policies in the natural environment and/or while keeping these animals in captivity. Zoo Biol 27:294-304, 2008.
