Our #sEEG study is now published in Nature Communications: rdcu.be/eIkoG! 🧠
Key finding: We discovered neural evidence accumulation for visual perception that's independent of report preparation—recorded from >3000 channels across 3 experiments!

We tackle a decades-old Q: does faster detection of bimodal targets come from a race or co-activation between modalities? And also a vital, orthogonal Q: is it one decision process or two?
A1: co-activation
A2: two!
