As a computational neuroscientist who has used ANNs to model brain data for 20 years, I want to suggest another way to think about these sorts of brain-ML/ANN comparisons: successful language comprehension requires representing the und

Yes!!! 1) Before the 19th century science was the domain of the landed gentry or those who could find sponsorship from someone of means. Things have been different since then, but positions have always depended on academic pedigree. It has

Oh my this article is painful to read on so many levels. It treats as important many phenomena that are either inevitable or uninteresting. (1) The fact that engaging in one task distracts attention from another task is obvious. People deri

It wasn't designed to be the best one, it was just the first one. So every great scientist who wanted to live in a nice area with nice weather and great state support (which UCB had in the old days) went to UCB. Then when the other UCs

Yes! In 1980 the state of California paid about 80% of the cost of an undergraduate student's education. Today it is about 8%. The state has dis-invested from higher education to fund other things (like prisons).

As far as I can tell the UCB administration is not happy about increasing enrollment. But they don't really have control over this. The UC system decides how many students each campus must accept, and the campuses have to go along with

Sorry I should have clarified this comment was addressed at the claims in the article that most of the brain is activated even for trivial tasks...

Please note that merely seeing some place in the brain activate in a functional MRI task does NOT necessarily mean that that location is either necessary, sufficient or even involved in representing information relevant to that task. Functi

To quantify the value of a method it is useful to consider the amount of information that the method recovers from the data stream, the prediction accuracy of the resulting models, generalization ability outside of the conditions used to fi

As an fMRI practitioner, I just want to point out that this problem has nothing to do with fMRI. It has to do with the weaknesses inherent in the most common methods for designing fMRI experiments, and for analyzing and modeling the data. T

The most sensitive fMRI methods don't do alignment at all, they do all data processing in the individual subject's brain space.

Much of the day-to-day variation concerns uncontrolled variability in blood pressure, arousal and attention. Those factors have enormous influence on the blood-oxygen-level-dependent signal.

The movie reconstruction from brain activity work was from my lab, thanks for the shout out! The problem with many methods of analyzing and modeling functional MRI data is that the signal-to-noise varies hugely across time, across individua
