ABSTRACT

A brain-machine interface is a communication system that does not depend on the brains normal output pathways of peripheral nerves and muscles. It is a new communication link between a functioning human brain and the outside world. These are electronic interfaces with the brain, which has the ability to send and receive signals from the brain. BMI uses brain activity to command, control, actuate and communicate with the world directly through brain integration with peripheral devices and systems. The signals from the brain are taken to the computer via the implants for data entry without any direct brain intervention. BMI transforms mental decisions and/or reactions into control signals by analyzing the bioelectrical brain activity.

WHAT IS BRAIN FINGERPRINTING?-KNOWLEDGE NOTES

Brain fingerprinting is based on finding that the brain generates a unique brain wave pattern when a person encounters a familiar stimulus Use of functional magnetic resonance imaging in lie detection derives from studies suggesting that persons asked to lie show different patterns of brain activity than they do when being truthful. Issues related to the use of such evidence in courts are discussed. The author concludes that neither approach is currently supported by enough data regarding its accuracy in detecting deception to warrant use in court.

Biomedical science 'rising in prominence'-MEDIPLACEMENTS

The prominence of biomedical science is rising in the UK, it has been suggested.

Writing in the Independent, Steve Connor claimed that over recent decades, biology has become an increasing priority.

This follows a time during the early half of the 20th century during which physicists “ruled the roosts”, he said.

He pointed to the government’s pledge to build a £500 million “cathedral of science” dedicated to biomedical science in London.

The UK Centre for Medical Research and Innovation will develop new treatments for the illnesses such as cancers, heart disease and strokes, flu and other infections. It is due to be completed by 2015 and will employ around 1,200 scientists.

Switchable Nanostructures Made with DNA-BIOMEDICAL NEWS

Opens possibility of responsive ‘nanomachines’ for applications in energy and data storage

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles — this time resulting in switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage. The work is described in Nature Nanotechnology, published online December 20, 2009.

Head massaging hat has been made

Head massaging hat certifies your dorkiness

Head massaging hat certifies your dorkiness

Massages are great, but I generally prefer the touch of another human over a machine.

Now Osim, the folks who brought us the massaging MP3 player, have one upped their earlier efforts with the uCrown 2 head massager. Combining air pressure technology, vibration massage, magnetic therapy, gentle heat, and even some built in speakers so you can play some relaxing Yanni music, the uCrown 2 is designed to relieve stress while relaxing your muscles. My only concern is that the benefits will be outweighed by the embarrassment of your family pointing and laughing at you.
