Relation between Fatty Diet and Brain Cells

Scientist’s endless efforts to conquer the problem of obesity are not new to the world. People are well-versed with the fact that researchers have been striving hard to eradicate the problem of obesity from its root. Their unstoppable thirst to look for a cure has made it possible to solve many unsolvable health complications. Likewise, a recent revelation of some factual information pertaining to obesity may help to address the doubt regarding effect of fatty foods on the cells of brain. Scientists undertook a research on mice. The research result advises that highly fatty foods initiate the production of some new brain cells which trigger weight gain in mice.

As per the opinion of experts like neuroscientist Seth Blackshaw of Johns Hopkins University School of Medicine and a published online report on March 25th in Nature Neuroscience, except few rare cases, most part of the human brain does not make any new nerve cells. But there is a place called the median eminence, which makes new nerve cells throughout the whole life of a human being and is also a vital place of brain’s metabolism.

During the animal research, Scientists kept few mice on unhealthy fatty diet and observed them for a particular period of time. They noticed that the production of new brain cells jumped in those mice, which were on unhealthy fatty diet for a particular period of time. Scientists observed those mice for couple of weeks more and found that they gained weight considerably. Research result indicated that the production of new brain cells in the median eminence part of the mice brain, which were on unhealthy diet, was four times higher than the mice which were on normal diet. To verify the result of the investigation and to analyse the impact of the new-born nerve cells, scientist Blackshaw and his colleagues stopped the production of new cells of few mice through careful targeted laser. The subsequent result brought an inspiring fact into notice that despite consuming same fatty diet those mice didn’t gain as much weight as other mice that still could produce the new nerve cells.

Scientists are investigating the original parent brain cell of the new born cells. The parent cell is known as tanycytes and can be found in both mice and human. Researchers are still unable to determine that how the new born cells control metabolism.

The result of the experiment is not ubiquitous as scientists are not sure if the human brain cells will behave the same way in response to fatty diet. Scientists all around the world are quite hopeful about the research finding because they think that if human brain cells react in the same way as the brain cells of mice, these nerve cells can be targeted for further treatment to cure obesity. According to endocrinologist Jeffrey Flier of Harvard Medical School in Boston, future research on the same subject may unveil several mysteries related to obesity. As per him, future medical research findings will be able to solve several confusions regarding obesity, diet, brain cells and brain’s capability in controlling and affecting hunger and eating habit in human.

Monitoring Software

The Internet can be tricky for parents to deal with because kids often need to use the Internet for school, but parents parents are often worried about the various activities that their children might be engaged in. Peer-to-peer file sharing can lead to lawsuits and even a criminal prosecution. Some teens might engage in activities online that are embarrassing to the family or may lead to viruses or hackers accessing the computer. Fortunately, there are various forms of monitoring software that can offer parental control.

Monitoring software can also be very helpful when parents are trying to learn what their children are up to, such as whether they are attending class or doing their homework.

Many teens use the computer purchased specifically for schoolwork to play computer games or chat with friends. Monitoring software can not only record activities on the computer, but smartphone software such as Mobile Spy can silently record the teen's GPS information, text messages and phone call information.

Monitoring software sits silently on a computer or mobile device and monitors all of the activities carried out on the device, encouraging the teen to consistently use the device for communication. Activity is usually uploaded to an online account so that the parent can monitor activity from anywhere without having to get close to the phone. This is crucial since parents will usually not have physical access to the phone without arousing suspicion.

Many monitoring programs also come with keystroke loggers, which log keys recorded on the computer, a contextual blocker, and features that allow parents to block certain websites. All of these features allow parents to have a peace of mind when allowing their teens to use the Internet.
