Excited to announce that my PhD research is now out in @Nature. We characterise a medial-frontal network for novel choice in primates involving a grid representation of value https://t.co/6hxFp4xhMw W/ Matthew Rushworth @MKFlugge@davidefolloni@LennartVerhagen @jerome_sallet 1/8
@LIGNEL_sncf Du coup les personnes qui marchent lentement ou avec des bagages ont raté le train et ils doivent avoir attendu 30 minutes le suivant. Ce n'est pas correct
@LIGNEL_sncf Gros n'importe quoi, j'attendais la L à la Defense vers minuit et au moment même que le train est entré en gare ils ont annoncé qu'en fait ça s'arrêterait sur un autre quai !! Du coup tout le monde a dû courir dans le sous passage et le train n'a même pas attendu plus longtemps
We still need many more native English volunteers for our simple test of math vocabulary -- click on this link:

Please pass the word around! it only takes 15 minutes.
Presenting my work on neural circuits for speed and accuracy changes in primates at #NVP2023 today in the session on "Deciding how to decide" at 2:30pm, w/ @HannekedenOuden@lauraabusta William Hopper @renee_cabbage Come if you're around!
Our review on Medial and orbital frontal cortex in decision-making and flexible behavior with @MKFlugge and Matthew Rushworth is out in @NeuroCellPress We survey this exciting research field, disentangling the complementary roles of several frontal regions https://t.co/h0b1b7DKby
Have you ever had to take a decision in an unfamiliar situation? How did your brain do it? Is the human brain special? I have written a post for the @UniofOxford science blog, talking in lay terms about our recent @Nature paper on novel choices in monkeys https://t.co/eWwzCNcEhL
@RyanPaulBadman1@nature@MKFlugge@davidefolloni@LennartVerhagen @jerome_sallet Thanks, and good point. Our model comparison suggests that instead of non-linear basis functions, the choices are better explained by non-multiplicative integration, which does not affect the map axes (Extended Data Fig.6)

@Niloy_Maity_ It does not mean "ablated" because in separate tests we observed no tissue damage. Activity may be inhibited or just altered, causing a transient functional disconnection of the area.
Together, these results suggest the existence of a medial frontal circuit in the primate brain causally involved in making novel choices – choices based on attribute integration rather than previous direct reinforcement – and grid-like encoding of such multi-attribute spaces. 8/8
Finally, we transiently disrupted MFC with a new focused ultrasound method. This caused choice behaviour to rely more on the two attributes considered separately, and less on their interaction, proving MFC’s key role in the value integration process underlying novel choice. 7/8
