Cortical dynamics of motion integration

A position is open for a bright and energetic post-doc for a project on the 
cortical dynamics of motion integration. This  project is part of a 
large-scale European Research Project, named FACETS, and financed for 3 
years. FACETS is a collaborative program linking neurobiological 
experiments, computational neuroscience and physics in order to implement 
functional cortical dynamics in novel computing paradigms using VLSI. ( 
The proposed project is to investigate the role of visual cortex in motion 
integration of elementary scenes in behaving monkeys. This study will be 
done at the visual cortex (V1, V2 and MT) using optical imaging of voltage 
sensitive dyes, combined with extracellular recordings and perturbation of 
neuronal activity (pharmacological or electrical stimulation). One main 
objective is to tackle the role of lateral interactions in integrating 
motion information distributed across visual space in the context of 
different spatial configurations of motion stimuli (Jancke et al 2004). 
Such dynamics will be compared with indirect measurements of the global 
motion percept, using induced eye movements as the relevant behavioural 
output (Masson et al. 2000, 2002). The possible involvement of cortical 
feedback loops will be studied by quantifying the impact of pharmacological 
inactivation or low-frequency stimulation of area V5/MT upon population 
activity at the level of V1 during the same visual protocols. A strong 
interaction with modelling studies is expected within the FACETS project. 
The applicant must have a PhD in Neuroscience with a strong experience in 
electrophysiology and good computer skills (Matlab, C/C++). Position is 
available immediately. Salary will be based on a CNRS scale.

The Team DyVA  belongs to the Institut de Neurosciences Cognitives de la 
Méditerranée, a CNRS laboratory conducting research in cognitive and 
integrative neurosciences. The Team is located on the CNRS Campus, 
Marseille which provides excellent research facilities. In particular, a 
new set-up for optical imaging in awake  monkey is now 
fully  operative  for this project.
