Expanding our view of vision
Every time you open your eyes, visual information flows into your brain, which interprets what you’re seeing. Now, for the first time, MIT neuroscientists have noninvasively mapped this flow of information in the human brain with unique accuracy, using a novel brain-scanning technique.
This technique, which combines two existing technologies, allows researchers to identify precisely both the location and timing of human brain activity. Using this new approach, the MIT researchers scanned individuals’ brains as they looked at different images and were able to pinpoint, to the millisecond, when the brain recognizes and categorizes an object, and where these processes occur.
“This method gives you a visualization of ‘when’ and ‘where’ at the same time. It’s a window into processes happening at the millisecond and millimeter scale,” says Aude Oliva, a principal research scientist in MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL).
Oliva is the senior author of a paper describing the findings in the Jan. 26 issue of Nature Neuroscience. Lead author of the paper is CSAIL postdoc Radoslaw Cichy. Dimitrios Pantazis, a research scientist at MIT’s McGovern Institute for Brain Research, is also an author of the paper.
Aaaaaaahhhhhh!!!!! So cool!
How is it that so many roads converge to the same destination?
If I began my life in a different place or moved myself now, would I end up somewhere else? Or would I still come to the same home at the end of it all?
Is there some kind of seed in me that it doesn’t care where I am planted, but will spill the same branches and the same fruit regardless?
Are my limbs but weathervanes to a much subtler master?
Who is running to the gate when my will gets weak, and who is at the door to answer him?
A drug that mimics some effects of alcohol but lacks its harmful properties would have real benefit for public health, a leading scientist has argued.
Professor David Nutt, the Edmond J. Safra Professor of Neuropsychopharmacology at Imperial College London, has identified candidate…
Why is it we think about the past as being less real? Is each second that passes by you less real than this current moment? Why would that be? Imagine, for a second, that ALL of those moments are just as real as this current moment. All the moments in what your life has been and all the moments in what it will be, ALL just as real and living as this current moment. Now imagine that you are like a kite soaring through each of those moments sequentially, and THAT is what time is. That is your soul traveling through time. All those moments already exist, they are what make up the fabric of this universe, we are just entities soaring through this pre-existing web of interconnected moments of all beings and all things. There are things outside of time that we will never get to experience because we are these kites flying through this web on the cusp of our individual time-winds. Things above the web, who knows what they are. . . . . . .
GENIUS! I had conceived of a similar idea but I didn’t know how feasible it was. Researchers at Michigan Tech are testing methods of communicating with disabled patients in varying states of consciousness and awareness (e.g. coma, paralysis, brain injury, etc.) by reading their brain activity after being given specific instructions. “The patients can be asked questions and given two things to think about for answers: playing tennis for Yes, walking around in their house for No. And different parts of their brain will light up. People can be conscious while appearing outwardly unconscious.”
