Imaging More Advanced Than MRI

The MRI was the most advanced way of diagnosing what patients were suffering from. It was cutting edge technology that gave very detailed images of the human body. Technology moves forward and advances are made.

Macquarie University with CSIC and the Institute of Photonic Sciences (ICFO) have found a way of producing images even clearer than MRI. It is done by using artificial atoms and nitrogen doped diamond nanoparticles. Extremely weak magnetic fields in the human body can now be detected. MRI resolution is millimetric. The new system "sees" down to a millionth of a millimeter.

This technique is not invasive. It will provide an understanding of intracellular processes. The problem with the new diagnostic system is that very temperatures are required to make it work. Artificial atoms are encapsulated in a diamond crystal. They can be manipulated by lasers, dragging atoms above the surface for medical diagnosis.

Depression Treatment from Magic Mushrooms

Doctors do not know how "recreational" drugs work. Police forces worldwide fight drug abuse, but the battle is being lost. Until medications can be developed to stop the euphoric effects almost immediately the battle will rage on.

There are possible benefits from some of these drugs. For example, magic mushrooms are being tested for treating mental conditions by psychiatrists. Neural circuits in the brain are altered by the use of the drug. What actually happens though was unknown, until now.

It was thought that dormant brain cells were being activated, the ones that are used during sleep. It has been discovered, however, that blood flow to the brain is decreased when psilocybin is used. MRIs showed blood flow reductions to the thalamus and cortical regions. The front and back of the brain are separated when the drug is taken. Primary sensory areas still retained good blood flow, while higher association regions became "starved" of blood.

Previous theories in regard to brain stimulation are now completely undermined. With brain separation taking place there are possibilities for medical uses. Depression is believed to be caused to a person's brain being too rigid. Such drugs as psilicybin from magic mushrooms could help by making the brain more "flexible".

Subliminal Advertising Actually Works

For years we have been told that subliminal messages on television and in films has no affect on us. Now we are informed that they do indeed work very well.

It is known that people pick up signals by intuition from other people. For example, poker players seem to know when their opponent has a good or bad hand. They don't know how - they just do.

A study sandwiched a subliminal picture for less than 50 milliseconds between two "normal" images. The subjects could then choose between two symbols, one being the sandwiched picture, to win money. The result was, subjects actually made money. MRI scans done at the time identified the ventral striatum region of the brain being the most active during the intuitive tests.

The research shows that subliminal advertising having a reward system attached can increase sales of a product. We can anticipate an increase in subliminal advertising.
