Download Knowledge Directly to Your Brain
For the first time,researchers have been able to hack into the process of learning in the biain,using
induced brain patterns to create a learned behavior. It's not quite as advanced as an instant Kung-fu down-
load,and it's not as sleek as cognitive inception,but it's still an important finding that could lead to new
teaching and rehabilitation techniques.
Future therapies could decode the brain activity patterns of an athlete or a musician,and use them as a
benchmark for teaching another person a new activity,according to the researchers.
Scientists from Boston University and ATR Computational Neuroscience Laboratories in Kyoto used
functional magnetic resonance imaging,or fMRI,to study the learning process.They were examining the
adult brain's aptitude for visual perceptual learning,or VPL,in which repetitive training improves a per-
son's performance on a particular task.Whether adults can do this as well as young people has been an on-
going debate in neuroscience.
Led by BU neuroscientist Takeo Watanabe,researchers used a method called decoded fMRI neurofeed-
back to stimulate the visual cortex.First they showed participants circles at different orientations.Then they
used fMRI to watch the participants'brain activity.The researchers were then able to train the participants to
recreate this visual cortex activity.
The volunteers were again placed in MRI machines and asked to visualize shapes of certain colors.The
participants were asked to"somehow regulate activity in the posterior part of the brain"to make a solid green
disc as large as they could.They were told they would get a paid bonus proportional to the size of this disc,
but they weren't told anything about what the disc meant.The researchers watched the participants'brain
activity and monitored the activation patterns in their visual cortices.
"Participants can be trained to control the overall mean activation of an entire brain region,"the study
authors write,"or the adtivation in one region relative to that in another region."
This worked even when test subjects were not aware of what they were learning,the researchers said.
"The most surprising thing in this study is that mere inductions of neural activation patterns corresponding to
a specific visual feature led to visual performance improvement on the visual feature,without presenting the fea-
ture or subjects' awareness of what was to be learned,"Watanabe said in a statement.
Watanabe and colleagues said this method can be a powerful tool.
"It can'incept' a person to acquire new learning, skills,or memory,or possibly to restore skills or
knowledge that has been damaged through accident,disease,or aging,without a person's awareness of what
is learned or memorized,"they write.
What have researchers been able to do with the help of the study?
A.Discover a person's learning process in the brain.
B.Make a person know how to do something without learning.
C.Set up different learning patterns for different people.
D.Enable people to learn Kung fu instantly.

[单选题]What is the price of anarchy?Technically,in transportation engineering,the price of anarchy describes the difference between what happens when every driver selfishly picks the fastest route and what the socially optimal traffic outcome would be.In the pre-mobile-app days,drivers'selfishness was limited by their knowledge of the road network.In those conditions,both simulation and real-world experience showed that most people stuck to the freeways and arterial roads.Sure,there were always people who knew the crazy,back-road route but the bulk of people just stuck to the routes that transportation planners had designated as the preferred way to get from a to B But a new body of research at the University of California's Institute of Transportation Studies suggests that the reality is far more complicated.In some scenarios,traffic-beating apps might work for an individual,but make congestion worse overall.And autonomous vehicles,touted as an answer to traffic streets,could deepen the problem This problem has been vastly overlooked,"Alexandre Bayen,the director of UC Berkeley,'s Institute of Transportation Studies,told me.It is just the beginning of something that is gonna be much worse.The situation then gets much worse because hundreds of people just like you want to go on the side streets,which were never designed to handle the traffic,Bayen says."So,now,in addition to congesting the freeway,you've also congested the side streets and the intersections While it's clear that these apps can put stress on local side streets,we still don't know what effect they may have on highways,or for traffic systems as a whole.This is an open problem,said Bayen Hence,we need to be very cautious in our conclusions They re building on pioneering work by researchers like Hani Mahmassani into the role of real-time information in shaping traffic conditions.In 1991,Mahmassani challenged what he took to be"possible misconceptions that information will automatically lead to improvements in traffic conditions.He was not alone.That same year,other researchers noted that information can cause drivers to change their departure times in such a way as to exacerbate congestion Nonetheless,most of this early work showed that when the percentage of drivers with access to in formation was low there was a major benefit for better-informed drivers.So,in the early days of Waze and Google Maps and automated routing at UPS,many individuals did experience substantial benefits rom these applications.The roads,as a whole,were probably also flowing better.Bayen does,in fact,have a suggestion for improving these apps,but the companies might not like it.He thinks the apps should spread out drivers on different routes intentionally,which would require collaboration among the mapping apps.Given the cutthroat nature of competition in Silicon valley thats a tough sell but it might help bring down the price of anarchy
Which of the following is true about the mapping apps?
A.It helps people avoid congestion and keep traffic flowing
B.It considers the conditions of the whole traffic system
C.It eases the traffic pressure of the main roads
D.It increases traffic congestion in general
