alt Hacker NewsRight, my point is sort of that both the BOLD response and fMRI sampling rates are far too "slow" (not nearly approaching the Nyquist frequency, I guess) a priori to deeply investigate something as fast as cognition.

Depends on what you mean by cognition, but as you yourself said, BOLD may be correlated with certain kinds of long(er)-term activity, and that in itself is very useful if interpreted carefully. No one claims to detect single "thoughts" or anything of the sort, at least I haven't seen anything so shameless.

Funny, because these exact measures [0] were brought up in response to a similar claim I made over a year ago [1] about the resolution of our instrumentation.
There would appear to be a worrying trend of faith in scientism, or the belief that we already have all the answers squirreled away in a journal somewhere.
Yeah I agree mostly. Cognition happens in multiple timescales, as such I don't think that fmri's sampling rate is a problem if we understand which cognitive phenomena it can actually address and which not. But there is definitely a tendency to not understand such limits of our tools.
