So, consider a high amplitude dimension of the data that, once normalized, no longer fits in the top PCs. SVD would rank it highly, while PCA would not.

So, SVD does not throw away the amplitude of each orthogonal contribution to the space.

PCA does.

There are times SVD will be much more useful than PCA for this reason.

I am not even sure it is a hypothesis.

I mean, it is a certainty that neural activity coding for a behavior is not using the full subspace of coding available.

It is interesting how many dimensions are in use.

But these are almost mathematically guaranteed.

Can you state the hypothesis?

On the other hand, googling "Brain Command Center" returns this

"... the prefrontal cortex acting as its "CEO" for higher-level thinking, and the hypothalamus serving as the "smart control center" for automatic bodily functions."

It is inevitable that such controversies emerge from neuroscience. We are discovering less and less new each decade about how the brain works, and those working on questions central to understanding higher cognition (a noble task) sometimes form increasingly dubious hypotheses about what is new.

They really underestimate the man-hours needed to renegotiate aims on 10-15k projects per year. Hours will need to be spent on each proposal by highly specialized experts.

What folly.

I do not believe the text of the proposition supports that statement. The prop was motivated by Texas, but does not depend on it.

I guess for some people, junior scientists are like eggs. If you have a dozen, you can break most of them because you only need a couple to produce an omelet.

So sorry!

And on top of all that, there is one nation that is throwing everything they have at NHP research, and doing so at a SMALL fraction of the cost of doing the work in the USA.

We are not there yet, but it is inevitable that labs in the USA will not be able to stay competitive in this arena.

And with the NIH administration, it would not be so far fetched for them to do something terminal, like, for example, withdraw core support from the 7 National Primate centers (more than one of which is already under attack from state/local government). Of course, there used to be more than 7.

The list of institutions supporting NHP research has been notably shrinking over the last 10 years. Including UCSF, for example!

The costs have skyrocketed.

And NHP grant proposals are getting irrational animal welfare concerns from non-NHP users who are unfamiliar with processes.

The ice is so thin right now....and could so easily be broken irreparably.

The term I heard was "least publishable unit", which in the lab in which it wad used was often the acronym LPU.

The LPU was central to that lab's approach.

It was a Novo Nordisk executive, representing a company that offers weight loss drugs. His name is Gordon Findlay, and I really hope he feels better!
