Brains, Computers, And The Future

Scientists are getting closer and closer to creating an interface between the human brain and a computer that can translate what people are thinking. This is especially helpful for people who are unable to communicate, such as those with complete locked-in syndrome.

Some researchers have tried to see if an interface that uses functional near-infrared spectroscopy, or NIRS, would work. Essentially, this method would measure brain hemodynamic responses that are usually associated with neuronal activity.

Scientists have tried to use brain-computer interfaces that depended on neuroelectrical tech, like an electroencephalogram, or EEG. The endeavor ultimately failed in its goal of helping completely locked-in syndrome patients communicate.

This latest technique though seemed to give hope to the study. It is a non-invasive brain-computer interface that combines the NIRS and EEG tech. This technique measures frontocentral blood oxygen levels, as well as electrical changes that occur in the brain. Although brain-computer interfaces in the past have helped patients communicate, the NIRS is the only technique that works on people with complete lock-in syndrome.

This also comes as great news for people who are unable to communicate, such as those with amyotrophic lateral sclerosis, or ALS, which can lead to paralysis later on, or those paralyzed because of a stroke or a spinal cord injury.

Another encouraging fact to note is that this is merely the beginning, as such studies are projected to have broader applications in the future.

Bioengineering: A Fascinating Timeline

When one mentions the term bioengineering, people usually think of advanced technology that could have only existed in the late 20th century. That, however, is rather inaccurate. The fact of the matter is bioengineering has been around for hundreds of years. But it was in the 19th century that bioengineering made a turn and became more prevalent. Here is a fascinating look at the important events that led to the development of bioengineering.

From 1791 to 1896

In a span of 105 years, a number of inventors and innovators came out with influential and then-state-of-the-art medical equipment. For example, in 1791, Luigi Galvani built the very first frog galvanoscope used to detect electricity using frog’s legs. In 1881, Samuel von Basch built the first sphygmomanometer, which was the tool used to measure blood pressure. The first X-ray machine was built in Germany in 1895, by Conrad Roentgen. He received the Nobel Prize for his efforts in 1901.

From 1903 to 1940s

The first half of the 20th century saw numerous leaps in bioengineering technology. Willem Einthoven began with the invention of the electrocardiogram, otherwise known as the ECG machine. Twenty-six years later, Hans Berger built the first electroencephalogram or EEG. In the two decades that followed, antibiotics, sulfanilamide, and penicillin were all invented.

From the 1950s to 1980

The technological revolution continued well into the second half of the 20th century starting with the invention of the electron microscope in 1950. Other notable inventions in this era were computer tomography (CT) and magnetic resonance imaging (MRI) machines. The gamma camera and SPECT came into existence in the 1980s.

Improving The Brain Processing Skills With Brainyarcade®

There are reports that say around 15 to 20 percent of Americans are affected by a form of learning disabilities or disorders. With cognitive brain dysfunctions impacting a great deal of individuals, treatments that go beyond conventional, largely ineffective remedies are needed.

An innovative program, which uses the most advanced brain-based technologies, helps re-train and develop the brain processing skills of the (eliminate) children and young adults. NTLgroup® calls it the BrainyArcade® program (not treatment – medical professionals get a little testy with the use of the word treatment).

It employs individualized programs that collect cognitive data through documentation and imaging, which are then summarized and analyzed. Wit these With this information, a development program is designed for the individual, in which his IQ development, learning, cognitive progress, social maturity skills, and behaviors are given focus.

The BrainyArcade® program allows the individual to undergo various exercises, such as electroencephalogram-based video games, computer-based exercises, and physical development tests. During these workouts, brain activity is observed continuously and stimulates his progress during the process.

Determining and addressing the cause of brain problems, the child will see an improvement in his ability to perform not just academically, but also in day-to-day life. The program is supported by concrete results, with patients’ average IQ scores being raised 15 to 25 points, as well as one to two functional grade levels.
