Liminar Investigations of Memory and Brain Organization

M-GATE training network opening


Memory research: Ground-breaking, Applied, and Technological Exchange is an ITN funded by the EU and coordinated by Francesco P Battaglia which will open the gates to research in memory at Radboud-Nijmegen, Univ Coll London, INSERM & AMU Marseille, NTNU-Trondheim, the Weizmann, SISSA and Janssen Pharma to 15 PhD students, to be recruited in the coming months. Dedicated website to be online soon.

Talking Potts, the new Human Frontier

limbo pilotFrom October, 2016, we have been latching on with analyses of cortical dynamics and language processes, after those by Eleonora, Sahar, Ritwik and Sand, in a new HFSP collaboration with linguist Naama Friedmann (TAU) and physicist Remi Monasson (ENS), which also focuses on understanding the phoneme manifold(s), with insights from grid-like neural  representations.

Thanks to Yuqiao's expertise, the first glimpse has been obtained of Yair's mind.

GRIDMAP project sailed homehyperbolic grid

Eugenio Urdapilleta has splashed heptagonal grids on the pseudosphere, while Federico has suspended dodecagonal ones in mid-air. Download the preprints below.

Their research has been part of a collaboration coordinated by Edvard Moser in Trondheim, including also Richard Morris in Edinburgh and Jorg Conradt in Munich and funded by the EU.
