# brain: related noise in perception, like a type of "groupthink"

<< The findings, (..) offer new insights into the limits of perception and could aid in the design of so-called neuroprosthetics-devices that enable people to regain some lost sensory capabilities. >>

<< because neurons are highly interconnected, when one randomly responds incorrectly and misidentifies an image, it can influence other neurons to make the same mistake. >>

<< You can think of correlated noise like a type of 'groupthink,' in which neurons can act like lemmings, with one heedlessly following another into making a mistake, >> Surya Ganguli

<< Remarkably, the visual system is able to cut through about 90% of this neuronal noise, but the remaining 10% places a limit on how finely we can discern between two images that look very similar. >>

<< With this study, we've helped resolve a puzzle that's been around for over 30 years about what limits mammals-and by extension humans-when it comes to sensory perception, >> Mark Schnitzer
