Research summary

My PhD is about spatio-temporal interactions of stimuli-induced activity in neural networks during sensori-motor transformation. Those interactions can be an integral part of a decision making system, but they can also shape the motor execution. The saccadic eye movement system came as the obvious sensori-motor system to focus on during my PhD due to the substantial quantity of studies from which it benefits, from psychophysics, neurophysiology and modelling.

Employment

2012: University of Provence, Marseille (France), 7 month:
Spiking neurons modelling of oculomotor saccadic system, focused on Superior Colliculus and its lateral connections. The aim was to test hypothesises explaining behavioural data recently found in our laboratory. The work tried to deal with complex spatial interaction between stimuli leading to the saccade selection.

2011: Charles de Gaulle University, Lille (France), over the year:
Firing rate neurons modelling of oculomotor saccadic system. The model controlled an eye in a virtual 3D world. It was based on an adaptation of Trappenberg et al.’s model (2001) and implemented eye muscle model. The work focused on information transformation required from Superior Colliculus to eyes muscles.

2010: INRIA, ETIS and URECA Laboratory, Lille and Paris (France), 3 month and half:
Theme 1: Kinematics analysis of human and robot movement during imitation tasks in order to compare two robot arm technology.
Theme 2: implementation and adaptation of a clustering algorithm based on mathematics distance invented by Daniil Ryabko (INRIA, Lille).

2010: Charles de Gaulle Universitée, Lille (France):
Fitts's law study on object grasping according to its size and mass as well as according to the sequencing and lateralization of movements.
