over 200 papers and 14 books in one year is so obviously insane that it almost hides the problem. what scares me are labs that now publish 23 instead of 12 pre AI.

So… we just found out that GPT sol can complete a complex online behavioral/cognitive study producing nearly indistinguishable behavior and subjective reports… right as we are about to launch. Is this doomsday for online cognitive testing?

I enjoyed writing this piece for The Transmitter. AI is a seismic change for science. What we make of it is up to us, but it’s a decision we can only make collectively. I hope more labs, and the field at large, will engage in finding a shared view of how we want to use AI.

Online Now: What can we learn from studying replay in humans?
dlvr.it
What can we learn from studying replay in humans?
Noninvasive methods are making it possible to study neural replay in humans. Although focused on alignment with rodent findings, human research often tacitly assumes that replay is linked to conscious, deliberate thought. This assumption represents a missed opportunity to investigate the links between replay and consciousness, as well as cross-species differences more broadly.

Fun "fact" I've been trying to estimate for a course on brains and neural nets: the human brain eliminates/re-creates somewhere between 1 - 170 million synapses per second, totaling to a mind-boggling 2 to 380 quadrillion changes over a lifetime. More on my guess below. Curious to hear feedback!
