Urgent decision-making between actions
NEWS (last update: Dec 31, 2020)
Very happy to find out that the team ATIP/Avenir label will be renewed and the research funded for two additional years (until August 2023).
Thank you to the Inserm and CNRS ATIP/Avenir committee for trusting my program.
Very grateful to Katja Heuer and Roberto Toro for making their beautiful poster free to download in high resolution. Aesthetic and educational decoration. Their paper on the evolution of neocortical folding across 34 primate species can be found here: 10.1016/j.cortex.2019.04.011
Very happy to see our latest paper discussed in the sensorimotor control and learning journal club. @Amelie_Reynaud showed how humans can flexibly adjust their decision and movement speed/accuracy trade-off depending on task constraints.
How do the cortex and the basal ganglia share labor during decision and action?
With Jean-Francois Cabana, Albert Feghaly and Paul Cisek we analyzed population activity from PMd, M1, dlPFC, GPe and GPi in two monkeys performing a decision task.
We show that decisions about actions involve a unified dynamical attractor system distributed across the cortex and basal ganglia.
Congratulations Clara Saleri for being awarded with a doctoral scholarship from the French Ministry of Research ! Very happy to welcome you onboard and I look forward to studying the neural bases of decision-making together !
Very happy to see the second paper of the lab accepted in one of my favorite journal, Journal of Neurophysiology ! Congratulations Amelie Reynaud and Clara Saleri on this important step toward a better understanding of the relationship between decision-making and motor control !
My Ph.D. research focused on the FEF, a major component of the cerebral network that is thought to contribute to decision making, as well as to visual and oculomotor processes. We used single-neuron recordings in monkeys to test the hypothesis that FEF neurons integrate signals from the hand to ensure adapted ocular exploration of peripersonal space.
My post-doctoral position in Paul Cisek’s lab provided me with the opportunity to pursue the exploration of complex integrative functions, i.e. decision making, in brain regions such as PMd, M1 and PFC. We investigated the neural correlates of dynamic decision-making in monkeys trained to perform a reach decision task. We showed that premotor and primary motor cortex activity reflects the competition between potential options and signals the commitment to a choice before movement initiation.
As a research associate in Paul Cisek's lab at University of Montreal, we explored the behavior and the neural bases of speed-accuracy trade-off adjustments during dynamic decisions and movement execution. We investigate this question under the affordance competition and the urgency-gating frameworks.
