Beijing time on September 8, United Kingdom daily mail reported that humans as a species may have made a lot of achievements, but part of the human brain has only tracked four objects at a time. This is based on the United States, a new study, it found that we work smart surprisingly limited memory. This study also reveals our event and spatial working memory can borrow in times of need extraordinary Visual and auditory processing network.
• Part of the human brain has only tracked four objects
”Will you buy a RAM only 4 per cent of computers?” United States senior author Professor at Boston University, articles Dawei·suomosi (David Somers) said. “Not 4MB or GB or 4k, only 4. So how on Earth is the human brain deal with all things? “
”There is too much information around, and our brain’s ability to deal with and very limited,” study lead author, postdoctoral researcher samansha·mihaerka (Samantha Michalka) said. “We urgently need attention functioning in this world. ” 20 billion didn t play burn games Baidu technology
Working memory is a system that is responsible for the temporary retention of and processing of information. Although it is used sometimes as a synonym for short-term memory, but these two concepts are not identical. In short-term memory we can retain much more memory, because it is not be liable for material handling or organization. Have a very limited capacity of working memory, researchers believe it can only hold 7 “chunks” of information. Or it could be numbers, words, letters, or other cells, but once you get beyond this capacity, memory cannot afford. Now, this number was reduced to 4, “one in two” humans are not good at such things.
• Eyes get access to Visual information and the ear’s auditory information can be merged into a
In this study, scientists believe eye of Visual information and ear, auditory information from access into a. They will then reach the vestibule of the brain, which is where abstract thought. Boston University’s team, including Director of the auditory neuroscience laboratory babala·Xien-Cunningham (Barbara Shinn-Cunningham), functional magnetic resonance imaging experiments were conducted to test the conventional wisdom.
Experiment reveals brain vestibule before one thinks the attention note is actually two staggered the network network support Visual support another hearing.
Scientists are curious about when and how to close collaboration both networks. “Our vision system is very good at dealing with space, but ability to process time generally,” Soames said. “But our auditory system, by contrast, processing time is incredible, but it is not good at dealing with space. In other words, when one is trying to locate something in the space, such as the acceleration of the ambulance, vision is more than hearing, but if you try to remember a time interval, the hearing is superior. ”
But if you want to use when the system is slightly less, what happens then? for example, if you have to remember the location of several noise, but at this time there are no visual cues. And that is what the scientists want to investigate problems. This led to another series of experiments, the researchers asked participants to complete space mission with the hearing and visually completing a scheduled task.
Experiments show that two networks cooperate closely, Visual network helps us to understand what’s going on in the space, and auditory networks to help our understanding of the events that occurred on the timeline.
”In a sense, we see the space, even if space is not Visual, we hear the timing and rhythm, even if the timing was not hearing. “This way, scientists say auditory and Visual help each other improve their capabilities. Precise adjustment of the brain map or may eventually lead to deeper understanding of attention disorder, and better tools to predict the consequences of brain injury.
