BREAKING: This is huge news, the EU's equivalent of the 🇺🇸Supreme Court's 2015 Obergefell v. Hodges ruling.
🇪🇺Court of Justice just ruled all 🇪🇺countries must recognise same-sex marriages granted in other member states.
This effectively legalises gay marriage across 🇪🇺

Congrats to those who were successful and commiserations to those who were not. You're excellent and the system is flawed - we need more funding for Australian science.
DECRA success rate is the lowest in 14 years, since 2012 (1st year the scheme ran).

This kind of stuff is why I say that I worry that the tools of neuroscience are not properly vetted
“Our findings challenge the conventional focus on low-dimensional coding subspaces as a sufficient framework for understanding neural computations, demonstrating that dimensions previously considered task-irrelevant and accounting for little variance can have a critical role in driving behavior.”
Neural dynamics outside task-coding dimensions drive decision trajectories through transient amplification
Most behaviors involve neural dynamics in high-dimensional activity spaces. A common approach is to extract dimensions that capture task-related variability, such as those separating stimuli or choice...

Another nail in the coffin for PCA?
- doesn’t linearize, distorting similarity metrics
- is biased by temporal jitter across epochs
- may miss important dimensions for transient amplification
If you think there is a state space, use a state space model!

new paper by Sean Westwood:
With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

We tested whether brief striatal dopamine release events influence the vigor of skilled movements. Despite popular belief, we did not find any evidence linking rapid dopamine dynamics to motor vigor on a moment-by-moment basis.
