뇌가 사고하는 순간 Remarkable video reveals 'why we say things before we think'


Watch a fleeting thought race across the surface of the brain in less than a second: Remarkable video reveals 'why we say things before we think' 




왜 우리는 생각하기도 전에 말을 하는가라는 

의문을 풀어줄 뇌 반응의 메커니즘이 공개됐다


1초도 안걸리는 찰라에 뇌표면을 지나가는 

사고하는 순간의 영상을 볼 수 있다.


1.노란색: 자극

2.적색 :언어

3.청색: 반응 순으로

Experts at the University of California, Berkeley, tracked the path of singular thoughts through people's minds as they underwent open brain surgery. Electrodes were hooked directly to the surface of each patient's brain, taking readings while they completed a simple call-and-response task. The scans show clearly how the brain acts in response to sight and sounds, which scientists say could explain 'why we say things before we think'. The researchers said the recordings could help us better understand how the brain's frontal lobe - known as the prefrontal cortex - coordinates activity like a conductor. Experts asked people to repeat the word 'humid'. The brain's language centre is shown lighting up (yellow in lett image) as it received the word, while a bit of cortex (blue in left image) then fires as the brain plans a response. The prefrontal cortex (red in left image) informed the response (right image) before it was given.
