Recent Study On Rats May Lead To Future Robotics

... For the study researchers used tiny electrodes to excite individual brain cells in the motor cortex of anesthetized rats. The brain's motor cortex, which controls movement, does not directly activate muscles, but signals a pattern generator that sends more detailed commands to the muscles. Researchers say ...

Using Mobile Phones For 45 Minutes Causes Excitation In The Brain

...hers found in the current study that mobile phones excite the neurons of the area of the brain closest to the phone when used for 45 minutes or more. However this effect is very temporary and corrects itself an hour later, the report said. It is though that alterations in the activity of the brain cells c...

Anti-Glycolytic Therapy Proved to be Effective Against Tumors

...tly a research scientist at Merck & Co. What may excite the growing band of researchers who are studying the Warburg effect, and cancer metabolism more generally, is the way the study resolves a long-standing debate about how and why cells switch to glycolysis in the first place. Warburg speculated that c...

Bottleneck in Blood Supply Makes Brain Vulnerable to Strokes

...anesthetized rat. They used focused laser light to excite a dye they had injected into the bloodstream. A chemical reaction of the excited dye “nicked” the blood vessel at the target location and triggered the natural clotting response. “The technique creates a clot while generating very little collateral...

Allergic Reactions to Insulin Have Declined

...e that retains the action of insulin, but does not excite the human immune response system. This way it will be active, but will not cause an allergic reaction. One potential reason for adverse reaction is that insulin is often injected in sudden doses. This gives unnaturally high peaks and troughs of the ...

Bladder Pacemaker For Incontinence

... impulses. "We knew that the sensory fibers that excite the bladder normally fire at a rate of 30 to 40 impulses per second," Grill said. "We used the same rate to trick the circuit to turn on." In another study, the researchers investigated the use of lower frequency electrical pulses for blocking unwa...

$1.5 Million Grant to Yale for Narcolepsy-Neurotransmitter Study

...this case, the transmitters act synergistically to excite the NPY cell. Under the NIH grant, van den Pol and colleagues will study the effects of both naturally occurring neuroactive compounds, as well as man made drugs, to determine how they influence the hypocretin cells, and, ultimately, cognitive arou...

Boffins Find Evidence for Novel Brain Cell Communication

... a disparity between the ability of nerve cells to excite one another, on the one hand, and to inhibit one another, on the other hand. The excitation and inhibition take place because the activity of nerve cells leads to the release of particular chemicals, called neurotransmitters, which act as a classic...

WBC Selective About Sugar

...sition. If we are able to use this unique sugar to excite the immune system, it may help the human body fight infection. Previously, everyone thought that these key cells of the immune system weren't picky and would eat anything that looked foreign, adds Fink, who is also an MIT professor of biology. Ifat...
