fMRI adaptation

Functional magnetic resonance imaging adaptation (FMRIa) is a method of functional magnetic resonance imaging that reads the brain changes occurring in response to long exposure to evocative stimulus[1]. If Stimulus 1 (S1) excites a certain neuronal population, repeated exposure to S1 will result in subsequently attenuated responses. This adaptation may be due to neural fatigue or coupled hemodynamic processes. However, when S1 is followed by a unique stimulus, S2, the response amplitudes should not be attenuated as a fresh sub-population of neurons is excited. Using this technique can allow researchers to determine if the same or unique neuronal groups are involved in processing two stimuli.[2]

Usage

This technique has been used successfully in examination of the visual system, particularly orientation, motion, and face recognition.[2]

gollark: I generate my bluffs via RNG now to avoid the terribleness of human random number generation (heavpoot has data on this), unless I don't and am trying to trick you into not making inferences from them.
gollark: Unless I didn't but am *not* trying to fool you all.
gollark: Unless I didn't and am trying to fool you all, of course.
gollark: I attempted to completely leave any chat here in the guessing phase out of my decision-making.
gollark: I'm probably going to do [REDACTED], having leaned more [DATA EXPUNGED] and [DATA FILLED WITH BISMUTH] this round, maybe something more [<:bees:724389994663247974>].
