Can someone help me out with the practical about neural basis of decision making? I have read Spronk et al., but I cannot make sense of these silly screenshots!
1. On the top left it is written either "Peak correct" or "Peak incorrect " in red. For instance, in Step 15 in the practical instructions it is written ". The ‘peak correct’ average is now overlaid as a red line on top of
the ‘peak incorrect’ average". This means that we are comparing the grand average of correct trials to the average of incorrect trials. The Spronk study is comparing correct and incorrect responses in placebo, cannabis and cocaine conditions (look at figure 2 of the article). However, I do not have a placebo condition of correct and incorrect trials... how can I than compare the graphs to a baseline?
2. I don´t have any amplitude values. When I look at my Y axis on the graphs of both the cannabis and the cocaine condition (so on 2 different screenshots), I read something close to -3,4 mV for both! Spronk reported for Cocaine ERN = -9.63 Pe= 8.32 ; for Placebo: ERN = -8.21 Pe= 6.68 and for Cannabis ERN = -6.51 Pe= 5.34 , which is absolutely not the case in any of my screenhsots!
Help is highly appreciated!
thank you! not yet, but I will upload them once I made them

I can only second what the "credit card" said. :D If you have any other summaries you could upload, I'd be more than grateful! :)

hey! can someone maybe post an overview of which brain region is meant by what? there were some articles using different names for the same area but I do not know that anymore and my tutor also did not get the differences... the only thing I know is :
Lateral PFC = inferior frontal junction (Task 2)
It was said like this in my tutorial, we made a distinction between conflict monitoring and response selection and said the first is a role of the dACC and the second of the SFG... maybe it would make sense to write Peter or ask it on the discussion board?
I used the study drive summaries and lectures :-) I don't know which articles specifically but I recommend first reading/learning the summaries (Hannah Klee, Lorenzo whatever) and then reading the main articles to grasp the whole concept. Good Luck
