Subject : Adaptive processing of time intervals in the brain

A 18 month postdoctoral position in computational neurosciences is available
at the Institute of movement Sciences (http://www.laps.univ-mrs.fr/) and
Institute of Cognitive Neurosciences (http://www.incm.cnrs-mrs.fr/) in
Marseille, France. It will be founded by the french ANR (NOAT
(ANR-07-NEURO-033-03) and MAPS (ANR-07-BLAN-0335-02) http://maps.loria.fr/).


Accurate processing of time intervals is necessary for precise sensori-motor
control. Time intervals from tenths of milliseconds to approximately 1-2
seconds are to be calculated by populations of neurons, considering the
typical time constant of a neuron is only of 10-20 ms. Two main hypotheses
on the underlying mechanisms are currently found in the litterature, namely
:
- "line attractors" approach proposed by Robinson (1989) and Seung (1996)
- "cascade of bistable units" approach, as proposed by Koulakov et al
(2002).
Both need a precise and somewhat tricky tuning of the synaptic weights in
order to obtain the expected behavior. The candidate will study the
conditions under which simple networks with loosely settings adapt their
weights to the constraint in order to approach the best "neuronal
integrator". This work will be carried out in close interaction with
experimental labs of Marseille. The candidate will have the opportunity to
develop further directions with the project members (models of time
perception, models of saccadic adaptation, ...).

The applicant should have a doctoral degree in computer sciences or applied
mathematics, with a good knowledge on computational approaches applied to
the biology of neuronal systems and neuronal modelling. Skills in
programming (Matlab, C/C++/ Python) are expected. Knowledge in dynamical
systems and/or control theory is a plus.

The position will be funded from 09/2009 to 02/2011 with possible
extensions. Salary will be based on experience.
