It’s not a fix for APCs, but it does challenge the gatekeeping model. And regardless of whether it’s perfect, I think it’s important that a high-profile journal is willing to take that kind of risk. eLife is one of the first high-profile journals to sacrifice its impact factor over principles.

However, despite achieving correlations higher than other ML-based models, there’s still room for improvement. Stay tuned to see how far we can push EEG-based decoding of striatal reward signals in future work!

If oscillations are modulated in amplitude from trial to trial, and those oscillations have a non-zero mean, they "create" an evoked response. It is a baseline-shift mechanism for ERP/ERF generation. Here is a simulated example of how alpha oscillations may generate readiness potential. #brainmovies

I have been trying to simulate event-related alpha amplitude decrease with the Jansen-Rit model. Turns out adding external inhibitory input abolishes alpha. Pretty obvious. But how does it agree with more alpha = more inhibition? #brainmovies

The Max Planck Society has begun an exploratory round table for open science. We are drafting some recommendations to leadership. Still a long way to go! But here are my notes on the most recent draft, just so you all know how I am trying to steer things.
Richard McElreath: It must not be overlooked that junior researchers DO NOT TRUST US. We, the directors, are a big part of the problem. We made this system, we remake it every year, and we benefit from it. What can we do to credibly signal our commitment to reform a corrupt research culture? My conversations with junior scientists in the society has taught me that directors are too often either indifferent or hostile to science reform. We cannot hope to convince our prize winning colleagues. Their egos are immune. But we can replace retirements with researchers who care more about integrity than their own prestige. This is important both for earning the trust of the junior researchers who really do the research in the MPG and for attracting excellent future directors and starting to earn the trust of the public. So I suggest two strong signals to our junior researchers (and the public): (1) we will reform recruitment and promotion at all levels to eliminate proxies like citation counts and journal brands in favor of reliability and sustainability; (2) we will make open science skills a core part of scientific training, through the graduate schools at a minimum, as conditions for the central funding. The most ambitious thing we could do, as hinted at in item 5 above, is to meaningfully invest in metascientific research. As the largest basic research organization in the world, the MPG is uniquely suited to studying research and its products from a broad perspective that includes the humanities, the sciences, and policy. Governments are already involved in science reform. Someone should study it in an organized and sustained way.

Big shake-up for dopamine theory? This new @NatureComms paper argues that VTA dopamine isn’t signaling reward prediction error but instead modulates force and performance. If true, it decouples learning from motivation and puts pressure on decades of RPE-based models. www.nature.com/articles/s41...

Functional connectivity (FC) is driven by 1/f. The approach: compute FC as usual, compute FC only with ROI where oscillations are 'present', then compare. Alpha lives, but not other bands.

Just finished reading this *excellent* article by Gabriel et al. which discusses which effects can be identified in randomized controlled trials. With DAGs!> link.springer.com/article/10.1...
Elucidating some common biases in randomized controlled trials
using directed acyclic graphs

Although the ideal randomized clinical trial is the gold standard for causal inference, real randomized trials often suffer
from imperfections that may hamper causal effect estimation. Stating the estimand of interest can help reduce confusion
about what is being estimated, but it is often difficult to determine what is and is not identifiable given a trial’s specific
imperfections. We demonstrate how directed acyclic graphs can be used to elucidate the consequences of common imperfections,
such as noncompliance, unblinding, and drop-out, for the identification of the intention-to-treat effect, the total
treatment effect and the physiological treatment effect. We assert that the physiological treatment effect is not identifiable
outside a trial with perfect compliance and no dropout, where blinding is perfectly maintainedTable 1 showing the Identifiability of target estimands depending on whether there is blinding, full compliance, and no drop-outAn example DAG from the paper.
Fig. 4: A blinded trial with noncompliance.

U are unobserved confounders, Z is treatment assignment, C is compliance, X is the realized treatment, S is the subject's physical and mental health status, Xself and Xcln are the treatment that the participant and the clinician believed the participant received, Y is the outcome.
