Your brain can perform better after a brief exercise

A study by Heath shows that people can cycle or walk briskly for a short duration, even once, and find immediate benefits.

  • Even cycling or a walk for a short duration could help
  • A task was performed to examine the study

Toronto, Dec 22, 2017: Students may please take note that exercising for a brief period before writing a test or going for an interview may improve performance. Researchers have found that just 10 minutes of exercise can prime the parts of the brain that help us focus and solve problems.

“Some people can’t commit to a long-term exercise regime because of time or physical capacity,” said study co-author Matthew Heath, Professor at the University of Western Ontario in Canada.

“This (study) shows that people can cycle or walk briskly for a short duration, even once, and find immediate benefits,” Heath said.

The findings, published in the journal Neuropsychologia, have implications for older people in the early stages of dementia who may be less mobile, and for anyone else looking to gain a quick mental edge in their work.

During the study, the research participants either sat and read a magazine or did 10 minutes of moderate-to-vigorous exercise on a stationary bicycle.

Following the reading and exercise session, the researchers used eye-tracking equipment to examine participants’ reaction times to a cognitively demanding eye movement task.

The task was designed to challenge areas of the brain responsible for executive function such as decision-making and inhibition.

“Those who had exercised showed immediate improvement. Their responses were more accurate and their reaction times were up to 50 milliseconds shorter than their pre-exercise values,” said Heath.

“That may seem minuscule but it represented a 14 percent gain in cognitive performance in some instances,” Heath explained, adding that he is conducting a study now to determine how long the benefits may last following exercise. (IANS)

Is New Google Glass-Based Solution a Blessing for Autistic people?

According to Dr Ned Sahin, Founder and CEO of Brain Power, a US-based science-driven company, Augmented Reality (AR)-powered wearable computers can help those with ASD gain confidence, clarity, understanding, social integration and self-sufficiency.

Google Glass — an eye-wearable device that made headlines in 2015 but failed in the consumer technology space — has now rekindled the hopes of millions of people with autism spectrum disorder (ASD) globally, including in India. Although no official numbers are available, at least 70 million people have autism worldwide, including over 10 million in India.

According to Dr Ned Sahin, Founder and CEO of Brain Power, a US-based science-driven company, Augmented Reality (AR)-powered wearable computers can help those with ASD gain confidence, clarity, understanding, social integration and self-sufficiency.

There is no cure for autism but early diagnosis and intervention with therapies does improve the long-term outcome.

“We need help. We need families and schools to support the first wave of technology for autism and special school communities.

“I am open to collaboration if there is an interest from schools, organisations and families from India. We can customise our Google Glass-based applications for autistic people in India,” Dr Sahin told IANS.

Brain Power is currently working with several schools in the US. The “Empower Me” wearable system has been used by hundreds of children and adults on the autism spectrum.

“The apps also encourage them to make eye contact and control repetitive behaviours — both of which are big challenges related to autism,” said Dr Sahin, a famed neuroscientist who studied at Harvard and MIT.

According to Dr Sahin, contrary to what most of the people think, kids actually treat wearable devices as fun and are facing no problem using them.

“We have discovered scientifically that people with autism enjoy using wearable devices and embedded software for socio-emotional learning,” Dr Sahin told IANS.

Each software module connects to Brain Power’s Cloud-hosted portal where Artificial Intelligence (AI) algorithms produce insights and predictions in real time.

The game-like apps collect numerical behavioural data — scientifically and rigorously — and present the child, family, school or clinic with insights and answers they can readily understand.

At AWS Public Sector Summit in Washington DC last month, Dr Sahin announced a couple of new products.

“We now have a package for schools consisting multiple AR devices. The devices and the software add more functionalities than we had before. It generates very good data about how kids are learning, their progress and whether young adults have the right skill-sets to get a job,” Dr Sahin explained.

Another new product is called “Learning Eye”.

In this technology, a camera is placed in the classroom which is connected to a computer that runs Machine Learning (ML) algorithms.

“AWS gave us access to its new product called Deeplens months before releasing it to the public. ‘Learning Eye’ uses Deeplens’ capabilities to run ML in the classroom in order to assist teachers as well as kids,” noted Dr Sahin.

The technology can detect if a student is paying attention or not. It can also detect if a student is writing a message on his smartphone in the classroom, giving a warning to the student while alerting the teacher.

“The teacher can also assess when the student is bored and initiate an immediate feedback to improve the student’s mood. She can get entire data about what is happening in the classroom,” Dr Sahin informed.

AWS Deeplens helps the Brain Power team run deep learning models locally on the camera to analyse and take action on what it sees.

DeepLens is easy to customise and is programmable using AWS Lambda — a serverless compute service that makes it easy to build applications that respond quickly to new information.

“We are very serious about maintaining privacy. Video footage stays in the classroom and is never sent to Cloud. Video processing is done at the edge of the Cloud to maintain complete privacy,” Dr Sahin told IANS.

The company has also developed a method known as “Fidgetology” which rapidly quantifies body language to assess mental health or to estimate enjoyment of ads or other media.

“Fidgetology” was developed in collaboration with AWS, using the company’s Cloud-based AI, ML and computer visions tools.

Dr Sahin is positive that Indian schools and organisations working in the field of autism will come forward to a life-changing experience.

“We would like to expand our capabilities to India. It all depends on the desire of the people to have the new technology and empower children and adults all along the autism spectrum to teach them practical life skills,” the neurotechnology entrepreneur hoped. (IANS)
