Please check out the second paper of the lab, published in the Journal of Neurophysiology. The study, led by Dr. Amelie Reynaud, shows an interesting phenomenon: human subjects tend to sacrifice their decisions when the movement they have to produce to report these choices are demanding in terms of accuracy. Data also suggest that there is no one single invigoration signal coordinating decision and action durations, but instead independent, yet interacting, urgency and vigor signals.

Please check out the latest paper published in the Journal of Neurophysiology describing an ICMS experiment performed in Montreal with Paul Cisek. We show that stimulation of monkey PMd and, to lesser extend, M1 delays the commitment to an action choice:

Thank you very much to Dr. Karen Reilly (CRNL-Impact) for letting me her IM and surface EMG recording system (Grass QP511) ! Great tool to accurately measure reaching movement onset and vigor.
Also, by looking at old material in the unit, I came across this beautiful Grass S88 2 channel stimulator!

The setup for the human experiments is ready !
A few software-related issues to fix, the ethical protocol to submit and wait for approval and experiments will begin. Expected date: January 2019

Lab setup in progress:
The office is almost complete, including brand new desk and computers !
The monkey ephy room is here, only needs some cleaning and then we'll start setting equipment up.
At the same time I'm working on an experimental setup dedicated to human subjects. Objective: cross-species comparison and fine-tuning of task parameters for monkey experiments
Please check out this book chapter in which Paul Cisek and I summarize our recent work on the role of the PMd/M1-BG circuit during decision between actions, propose a way to map neural circuits and decision types and finally speculate on the respective functions of cortex and BG during goal oriented behavior.

Great speakers and attendees, cool conversations and beautiful weather at the "Probabilities and Optimal Inference to Understand the Brain" workshop in Marseille.
Thanks to the organizers for putting together this great event !
