Researchers implanted targeted electrical arrays in the brains of a few dozen volunteers — specifically in brain areas involved in memory. The effects and implications of these systems raise questions that are worth consideration.
The Burden of Perfect Memory Ina team led by Alcino Silva at the University of California, Los Angeles engineered a strain of mutant mice that looked and behaved like regular mice, but certain neurons in their brains fired more actively.
Mice with these active neurons learned about three times faster than normal mice.
Their memory was more accurate than that of any other mice on the planet. They used a very common form of learning experiment: They gave the mice a mild electrical shock in certain cages, but not in other ones.
Perfect memory, then, is a double-edged sword, and not just because of the risk of lifelong PTSD as a result of one painful experience, like the mice getting shocked in their cage. Take the famed case of Solomon Shereshevskya patient who participated in a wide range of studies in the s after researchers discovered his ability recall just about everything.
Toward the end of his life, he took to writing his memories on paper only to burn them. Where should we draw the line? As you attempt to build a mental map of local landmarks, your brain is also laboring to hold the list of errands in your working memory — both tasks suffer as a result.
But what if you had a brain implant that could grant you perfect recall of each task?
Ina team led by Harvard neuroscientists Edwin Robertson and Daniel Cohen used a technique known as transcranial magnetic stimulation TMS to take a step in that direction. They managed to prevent interference between competing forms of memory, enabling volunteers to memorize lists of items, and learn new motor tasks, in quick succession without either form of memory losing its sharpness.
Imagine having an implant that does this for you all the time. Instead of breaking in between tasks, you could learn a new set of driving directions, memorize a grocery list, and, just for fun, learn a dance routine, all without requiring any down time.
Every step would stay as sharp in your recall as it was at the moment you learned it. If you could essentially be in cram mode all the time, why ever stop?
But if you had the option to keep your memory turned on all the time, would you? Or are there some memories that are better to forget — or simply not necessary to remember?
They gradually built up a library of brain activation patterns that corresponded to specific colors, shapes, and angles of orientation.
Why not sign the whole family up? Your neighbors, and everyone else in the neighborhood, will probably want it for their kids, too.
In short, if supercharged memory comes within reach, is it a human right? If a few parents choose not to get memory implants for their children, is that child abuse? The field is in its infancy, but one day, strange as it might sound, your children — or their teachers or doctors — could come to you with pointed questions about memory implants.
What would you say if that time comes?In , researchers at McGill University in Montreal showed that reliance on GPS might reduce activity in the hippocampus, a part of the brain we use to get from A to B. Dec 22, · Scientists are in the early stages of developing devices that could theoretically give us perfect memory, raising some questions worth consideration.
Modern computer systems which can be primarily based on integrated circuits are small enough to fit into mobile gadgets, however, imagine having a computer a good way to suit into a ashio-midori.come a global wherein everybody can use modern IT without being a professional. But the revolution has been both a blessing and a curse, for it has had the unintended effect of raising expectations for technical progress.
We are assured that rapid progress will soon bring. Gizmos and Gadgets: A Blessing or a Curse? Is modern technology in general a blessing or a curse? As the youngest (at that time) professor at Moody Bible Institute in Chicago, I taught the first class ever in the use of electronic media to support Bible teaching.
- Modern society involves the transition of a new era: the transition is partly brought out through the use of cultural tradition, and through the production of new ideas and the invention of new techniques.
