Really good to be studying guppy and a robofish. We need to get down to basics.

@MolemanPeter
The trouble is Musk doesn’t publish. He presents demonstrations as if was trying to sell a new Iphone.

@biorxivpreprint

John Duncan would be pleased with these results given his views on a multiple-demand system The difference is that it looks to be a general principle of brain function.

@hugospiers

And SWR can be found in humans.

@DMN

Eleanor Maguire has used optical pumpted magnetometers to show that when we recall events from our life or imagine future events the medial prefrontal cortex is activated before the hippocampus, and so ''drives' it. It is connected via the retrosplenial cortex (which then connects with the hippocampus).

@smfleming

Hasn't Hakwan Lau been saying fpr a long time that the prefrontal cortex acts as a reality monitor? And used signal detection theory to model it? Doesn't take way from an empirical demonstration that indeed signal strength is the critical variable.

@maxpool

Patients with schizophrenia who hear voices have strong activation in the superior temporal auditory areas. What is not clear is whether these are driven by a top-down effect or not.

Generative AI is transforming tokenism and "cosmetic diversity" in new ways. Levi's is planning to use AI-generated models so it doesn't have to hire people of color in the role.

@Andrew_Hardaway

This is dreadful. It is clear that the managers are risk averse. But students are of an age when they take risks. Clearly the result is a disaster.

@hugospiers

Why use fNIRS rather than OPMs. I understand the advantages of fNIRS over fMRI. But surely the aim is to understand HOW the brain works and that requires a msec resolution.

@ProfSimonFisher

But will it tell you why he was a genius? Einstein's brain doesn't.

@deevybee

At 8 I went 240 miles from home to learn Latin and Greek. One of of the masters left because he was feeling boys up. No doubt he got a good reference and moved to another school (like Captain Grimes in Evelyn Waugh's Decline and Fall.

@smfleming

Stunning result!

@manuela_piazza @hugospiers

This is using eye movements ax evidence, not a verbal report. TOM is not developed until 4 and it continues to develop throughout the teenage years.

@deevybee

At boarding school (aged 8 to 18) we had a lesson at 7.30am followed by chapel on all weekdays. Taught us to run the Empire, in combination with rifle training and parade ground mauling. Made us what we are, damaged souls.

The EU is requiring Musk to take on more staff to moderate the site. Good for the EU!

The FDA has not agreed to Musk’s request to try electrode assemblies on people. Nor should they, given the very bad record he has of treating the macaque monkeys he has been using in preliminary studies.

Exciting work by Wu, Mitchel et al (arXiv >cs>arXiv: 2302.04449.

Deep Mind can learn Atari games, but it takes very many trials. By using an AI language model to read the manual for the game, Wu et al were able to demonstrate that the game could be. learned in many fewer trials.

The relevance is that it take many trials for a macaque monkey to learn a cognitive task for reward. But a person can do the task immediately by simply following the verbal instruction given by the experimenter.

@ekmiller

Accepted.
