Ventral striatal plasticity and spatial memory
|

Pascal Roullet |
Deep structures of the brain are responsible for our memories indicates a study recently published on PNAS, fruit of collaboration between the Sapienza University of Rome and the University Paul Sabatier in Toulouse.
Until now it was thought that the cerebral cortex was only responsible for remembering facts, locations and faces.

Disentangling pedestrian movement in a crowd |
How do pedestrians move in the street? And how do they interact one with each other? |
Scientists from the Research Center for Animal Cognition (CRCA, Toulouse University 3/CNRS) and from the Swiss Federal Institute of Technology in Zürich have run a series of studies in order to further our understanding of human collective displacement in urban zones. |

Their realistic models of crowd movements, published on april 7th in PLoS ONE, may help to improve pedestrian traffic management in crowded situations.

Reorganization of a neural network associated
with long-term memory |
What are the structural consequences of the formation of memories in a brain able to learn and remember, and amenable to the structural analysis of its constituting networks ? Is long-term memory accompanied by volume changes of certain brain regions and, if so, what are the links between possible changes in brain structure and those in neural activity after memory formation ?
|

|
In order to answer these questions, Benoît Hourcade and Emmanuel Perisse (PhD students at the CRCA), together with Jean-Christophe Sandoz (research associate, CNRS) and Jean-Marc Devaud (assistant professor, Paul Sabatier University) studied the formation of olfactory long-term memory in honeybees, and have analysed in parallel the volume changes in the antennal lobe (first odorant processing centre in the insect brain) that go along this memory formation. |
