Brain Computer Interface Turns Mental Handwriting Into Text on Screen, Could Help People With Paralysis

A team of researchers at Stanford University have, for the first time, decoded brain activity related to writing by hand. The researchers collaborated with a participant with paralysis(inability to act or function properly) who had sensors implanted in his brain. The team then used an algorithm that identified the letters the participant imagined and attempted to write.
The system then displayed the same text on-screen in real time, meaning as and when the participant imagined them. Krishna Shenoy, the study co-author and a Howard Hughes Medical Institute Investigator at the university, said the innovation, with more development, could well help people with paralysis rapidly type without using their hands.

In the experiment, the participant could type 90 characters per minute, which was more than double the typing record set by the previous “brain-computer interface".
An injury or a disease may take away a person's ability to move but the brain's neural activity connected with walking, holding a cup of coffee or tea, or even speaking a sentence remains. And this activity is exactly what the scientific community can tap into to enable people with paralysis or amputations to express their thoughts or even carry out an activity.

The Oldest Phone In The World

  The first cellular telephones are called Dyna Tac. It is manufactured from 1983-1994. It received approval from the U.S. FCC on September 21, 1983. Martin Cooper of Motorola made the first publicized handheld mobile phone call on a prototype DynaTAC model on April 3, 1973. This is a reenactment in 2007.    The dimensions of this phone are 3300 x 898 x 445 mm, vol. 1318710 cm³.This cellular phone is available at the minimum weight of 2 pounds. It is used in the ALOHAnet system, including metal–oxide–semiconductor (MOS) transceiver and modem technology. It has nine additional key.They are Rcl (recall),Clr (clear),Snd (send),Sto (store),Fn (function),EndPwr (power),Lock and Vol (volume).Minimum sim is used in this phone. In 1983, The market price for this phone is $3,995.   In 1930, Travelers could place phone calls from and to ocean liners in the middle of the Atlantic Ocean. The process was driven by Marine VHF Radio and cost $7 a minute. In 1984 Motoro...

LEECH THERAPY

  Early Egyptian, used leeches to treat the nervous system, abnormalities, dental problems, skin disease and infections. Nowadays mostly used in plastic surgery and microsurgery. The saliva of leech secretes peptides and proteins which prevent blood clot.     These secretions also called anticoagulant to keep blood flowing will help to heal the wounds. This therapy is seeing a revival or renewal due to its simple and inexpensive means of preventing complications.     These medicinal leeches most often come from Hungary or Sweden. Leech has 3jaws in them two tiny rows of teeth. They make a hole in a person skin and insert the anticoagulant through their saliva. Each leech allows extracting (up to 15ml of blood) for 30 to 45 minutes.    Chemical derive from the saliva of leech made into pharmaceutical drugs that can treat hypertension, haemorrhoids, skin problems, arthritic appreciate treatment for common joint disease osteoarthritis, ci...
