Liminar Investigations of Memory and Brain Organization

TRIPs, also without Ayahuasca

Transitions in Retrieval-Induced Productive Sequences is a PRIN-funded collaboration with Elisa Ciaramelli, from the University of Bologna, to explore the mechanics of mind wandering, in its cognitive and neuronal dynamics. Check the trilogy of Kwang Il Ryom papers below.

Finally for Danteday, with help from Ariosto

Just in time for Dantedì, March 25, and two years after submission, our study of the memory enhancing effects of meter in Dante (and in Ariosto) has been upgraded from preprint to paper; having received favourable reviews by Lev Blumenfeld and Johann-Mattis List - many thanks! Visible on Open Research Europe

M-GATE training network running

Memory research: Ground-breaking, Applied, and Technological Exchange is an ITN funded by the EU and coordinated by Francesco P Battaglia which is not waiting for stone gates to open, to research memory at Radboud-Nijmegen, Univ Coll London, INSERM & AMU Marseille, NTNU-Trondheim, the Weizmann, SISSA and Janssen Pharma.

Talking Potts, the new Human Frontier

From 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 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 home

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.
