Hello,<br>
<br>
Please see details below of an upcoming seminar which may be of<br>
interest. If anyone is interested in joining us for lunch or meeting<br>
with the speaker let me know.<br>

Title: Unveiling the neural code of wandering animal searches<br>
<br>
Abstract:<br>
It is well established that animal movement follows Lévy patterns.<br>
The underlying generating neuronal dynamics of such a behavior is<br>
unknown. In this paper we show that a novel discovery of multifractality<br>
in winnerless competition (WLC) systems reveals a potential encoding<br>
mechanism that is translatable into two dimensional super-diffusive Lévy<br>
movements. The validity of our approach is tested on a conductance based<br>
neuronal model showing WLC and through the extraction of Lévy flights<br>
inducing fractals from recordings of rat hippocampus during open field<br>
foraging. Further insights are gained analyzing mice motor cortex neurons<br>
and non-motor cells signals. The proposed mechanism provides a plausible<br>
explanation for the neuro-dynamical fundamentals of spatial searching<br>
patterns observed in animals (including humans) and illustrates an until<br>
now unknown way to encode information in neuronal temporal series.<br>
