The human brain is more complex and has far more capacity than a billion dollar computer. So far the research done on the brain is still in its nascent stages. What mysteries and secrets it holds for humanity in the future remains one of the big questions.
The 21st century has been called the “Century of the Mind”. Research into the functions and capabilities of the wonderful organ that is the human brain will skyrocket with duration as mankind enters a new era in discovery and invention.
The powers of the brain to comprehend the farthest phenomena of the known universe and delve into the inner journey of intelligence and intuition may just about define us as a species with something special about it.
We may be a reed, as an ancient philosopher said, but we are a thinking reed. It is this special quality of self-consciousness that has made all the difference in the end.
Criminals are dealt with by the justice system in a manner that may either let them go scot-free or put them behind bars for life. Many times culpability is decided on the wrong factors. The reason is the intentions and motivation of the criminal minds. Yet now science has come to the rescue. The brain scans of criminals show whether they committed a crime knowingly or recklessly. It all has to do with their mental state.
The brain scans of 40 subjects were taken while they carried a suitcase some distance. They were told that it contained drugs. What the brain scans of these test subjects showed was that some of them were not so sure whether the suitcase contained illegal drugs or not. Thus the emergent science of “neurolaw” may have applications in the field of criminology in the future.

By stimulating the brain via electric signals, the short-term working memory can be enhanced to a considerable extent. This was demonstrated by scientists in the lab.
Such a procedure could have applications in the future on patients who are suffering from trauma, stroke and epilepsy. It basically involves the administration of transcranial alterating current stimulation (TACS) to various areas of the brain in order to bring the brain waves into synch with each other.
The scans show that stimulation ‘in beat’ increases brain activity in the regions involved in task performance. On the other hand, stimulation ‘out of beat’ showed activity in regions usually associated with resting. Credit: Ines Violante
The theta stimlation was applied in a synchronized, unsynchronized and short-bursts-of-signals manner. The first one was successful in boosting working memory. This technology holds a lot in store for humanity as far as the future amelioration of brain diseases is concerned.

The scientists have found that the mind is a much more active entity that was the erstwhile presupposition. It consists of dendrites which connect up with each other. These go on to form the neurons. The brain has certain electrical patterns that appear in the form of spikes along these dendrites.
While they occur in the neurons, they also simultaneously occur in the dendrites as scientists have just found out in recent experiments with lab rats. The brain is apparently active both in its sleep phase and its exploratory time. This points towards the future application of this research in the construction of supercomputers.

Drinking 30ml of concentrated blueberry juice a day leads to a betterment in brain function, cognitive improvement and memory enhancement. This was found to be the case among a group of elderly people who were the subjects of the study. They were given the concentrate to drink on a daily basis for four months and MRI scans of their brains were arranged for before and after the study.
Not only had they achieved a sharper brain down to the last senescent individual but they had also widened their memory banks. Thus the flavenoids in a plant-based diet may help fight inflammation in the mind and act as an anti-oxidant to boot. Risk of dementia is minimized among the elderly by consuming five portions of fruits and vegetables per day.

The human brain continues to show activity long after death. This was tested in four terminally ill patients who were taken off life support machines. One of them actually showed delta waves on the EEG that remained extant for a full 10 minutes.
The definition of life and death is not so simple as this study shows. Where life ends and death begins is at best murky territory. As far as death is concerned, it may be a mystery, yet the phenomenon of consciousness has been elucidated thanks to this research work.

For a dollar a mini-brain is a possibility. This happens to be a small bunch of tissues and neurons that imitate a minute portion of the brain with remarkable accuracy. While these mini-brains, built by neuroscience, have no consciousness or blood flowing through them, they nevertheless mimic the real brain by a close margin. The electrical impulses going through their circuits are a marvel to behold. Thousands of such brains have been churned out uptil now. Some skin cells samples and other components go into the ingredients of mini-brains.
Brain damage causes the destruction of brain cells. It is not something to be taken lightly. A brain injury whether it is due to trauma, stroke, tumor or illness may land you in serious trouble for the long haul.
So be prepared.
Traumatic brain injury and acquired brain injury are the two types that are commonly found in this category, according to WebMD. Brain injury often causes such symptoms as: headaches, confusion, memory issues and nausea.
Besides the brain injury caused by trauma, there is the other kind which may be due to: poisoning, infection, asphyxia, stroke or heart attack, tumor, aneurysm, neurological problems and drug abuse.
The synmptoms are many but the treatments consist of: physical therapy, occupational therapy, speech and language therapy and psychological support. People ought to take preventative measures to offset the chances of getting injured in such a delicate region as the brain.
Tumors come in all shapes and sizes. There is always the surgical option. Then there is radiotherapy. Finally, there is chemotherapy. The decision is ultimately yours if you contract a brain tumor.
Yet expert advice is also of the essence here. The type of tumor, its position, its size, its grade and last but not least your chronological age are of paramount importance in this decision. Also the use of steroids and antiseizure and antiepileptic drugs for the myriad symptoms may be a necessity.

The brain responds to what you feed it (both literally and metaphorically). Herbs such as Gingko Biloba may be effective as an agent that reverses or at least halts the progress of Alzheimer’s Disease. It does this by increasing blood flow to the brain.
While the research on Gingko Biloba remains sketchy at best, it nevertheless shows promise as a cure for the “forgetting disease” and general symptoms of dementia. It should not be taken with aspirin or other blood thinners though.
Basically, it belongs in the realm of Traditional Chinese Medicine. Omega-3 fatty acids found in certain oily fish such as salmon and sardines also enhance brain power. Then there are other brain-enhancing agents such as the amino acid L-Carnitine and DMAE.
A novel technique which has come up may spell the death knell of glioblastoma. This is a tumor in the brain. By the specific targeting of an enzyme, the spread of the tumor can be halted. Such a tumor has thread-like tentacles that infiltrate into other parts of the brain.
Thus it is very difficult to remove. The blockage of enzymes ADAM10 and ADAM17 may stop the tumor dead in its tracks, according to The Sun. This devastating disease can be targeted via a series of palliative therapies which will incorporate this new technique in their contexts.
Exercise has been called the fountain of youth. It virtually rejuvenates the brain via the cocktail of chemicals that it releases (endorphins and catecholamines come to mind).
The reactivation of neurons in the mind is a very real effect of vigorous exercise. Experiments with mice show that exercise can heal their brains. This process works in human beings too.
There is an optimal amount of exercise that hits the sweet spot and has a salubrious effect on the brain, according to ABC.net.au. Too much can be harmful though just like too much of a good thing is bad.
While electrical stimulation of the brain may hold the cure for depression, it is a very precarious methodology to adopt. Mild electric currents may not be so invasive yet they carry the same side effects as the administration of drugs.
DIY brain stimulators have their dark side. The potential for abuse exists. Seizures could be triggered as a result of such self-experimentation.
A new study points out the fact that math skills may not necessarily be connected to vision alone. There may be more here than meets the eye (no pun intended).
The problem came up when the math skills of both ordinary and blind people were compared. There was not that great a difference between the two. The brain network responsible for the tasks needed to solve math problems was the same in either category.
The fact that one of them could not see thus disproves the visual bias hypothesis in math functioning. Blind people had been thought to struggle with math since they could not see and thus had to do everything using the power of their memories. Yet such is hardly the case. Math is not as simple as a visual-spatial thing.
A series of brain microchips can now allow a paralyzed person to feel the sense of touch via a robotic extension. This is a modern day miracle in the making.
A patient who is unable to move his hand or legs since breaking his neck in a car accident ten years ago has felt something for the first time. Scientists implanted four chips in his brain.
With these he can now manipulate a robotic arm using just the powers of his mind. He can actually feel the sense of touch when someone strokes his fingers. This is the first time a prosthetic has allowed a person to feel tactile sensation via direct stimulation of the brain.
The man said that it felt absolutely wonderful. He actually felt the fingers of his hand being touched and pushed. It was a miracle. The findings of this research were published in the journal Science Translational Medicine.
The brain is a dynamic organ and in no way can it be called static in its functions. What we call mind is a highly complex and infinitely integrated mechanism that may actually be metaphysical in nature.
Don’t Miss: The Best Pokemon Gifts The Fluctuating networks of the human brain, developed by Stanford scientists, tend to go up and down in accordance with the complexity of the task at hand.
Therefore the brain can upgrade its activity levels at the neuronal level to match the greatest of tasks. However, in the resting state, the brain is relatively placid and composed in its behavior.
Scientists have found a new pathway in the brain that can be dealt with in order to alleviate depression. The manufacturing of a special drug that could affect this pathway would be ideal. The search for the perfect antidepressant is on.
The current list of antidepressants have mostly failed to counter depression. Many patients do not respond to them with much alacrity. Between 10% and 20% of the population has depression and the symptoms may be ameliorated but the disease is for life.
Designer drugs that follow certain specific pathways in the human brain may be the ideal treatment for depression in the future. The research in the lab is a project under construction.
For one thing, how antidepressants work in the human brain is being looked into very closely. The discovery of new chemicals and channels for the relief of depression are underway.
Prozac and other tricyclic antidepressants tend to target a route in the hippocampus termed the BMP signaling pathway. This signaling pathway works in such a manner that it controls cellular functions.
A rush of chemicals takes place and the connections from one molecule to another leads to the cells firing one after the other. The signals thus gets relayed across the length and breadth of the neurons of the brain.
Prozac and tricyclics tend to inhibit this pathway. The result is that more neurons are produced. These neurons affect mood swings and memory functions.
Prozac acts on many centers in the brain. After confirming the BMP pathway, scientists tested a brain protein called Noggin. This was done in mice in the lab. It generated neurons.
The scientists postulated that this could have an antidepressive effect.
A brain simulator from Stanford University is meant to facilitate surgeons in their job. It especially simulates brain swelling thereby lending surgeons a chance to practice their profession in a safe and secure manner.
The method used to operate on a trauma is termed decompressive craniectomy. This is a brain swelling and the patient’s brain is allowed to take up space thereby saving the person after the head trauma.
Nevertheless, there are complications involved in the process. When the brain oozes out of a hole in the skull, some of the axons stretch and break. This could prove to be quite problematic.
Yet this novel tool-of-the-trade can decrease the chances of damage. It guides the surgeons in their efforts to cut a hole and make it fit the right proportions. It all ultimately depends on the type of trauma.
For the very first time, a novel tool has been developed that will allow the experts to interactively find out the process that occurs in the human brain while it is in hibernating mode or active.
The researchers also have their hopes set on the fact that via this tool, they might gain a better understanding of how neurological diseases such as Alzheimer’s affect the human brain.
It is called the Brain Modulyzer and it happens to be a software that integrates various views of a normal MRI reading. These include heat maps, node link diagrams and anatomical sights and they help in providing the milieu for brain connectivity information to be gathered with alacrity.
This tool lends a new framework of visualization and fresh techniques that help find out more about the brain. Observations from various angles are made possible thanks to this tool. Other tools do not connect well with brain anatomy. Yet this one is just perfect for accomplishing this task.
The tool will help in the construction of a model of various brain diseases. Hopefully, thanks to this instrument of intelligence, Alzheimer’s and dementia may one day become things of the past.
Alzheimer’s Disease could be halted thanks to a gene injection to the memory centers of the brain. The gene could thus clean out the glutinous plaques in the brain. Once the damage control has been finalized, Alzheimer’s Disease is something the patients can literally say good riddance to.
This cutting edge research began about half a decade ago. Scientists found a protein called PGC1-alpha. It happens to play a very important role in clearing up the build-up of amyloid beta plaques. However, the patients with Alzheimer’s do not produce enough of this protein.
Yet now we have a targeted gene that can help this protein produce the plaque-clearing agent. Those rodents that were treated in the lab with this sort of gene therapy recovered their brain memory centers.
The plaques were wiped out and they did much better in memory tests than the control mice. This methodology could thus one fine day actually stop the disease or even reverse Alzheimer’s down to a zero level in its occurrence. That will indeed have been a miracle.
Scientists have found the part of the brain where depression has a physical impact making way for new therapies Depression is a disease which has been increasing in many populations around the world with an alarming frequency. The disease is becoming a common state in modern society, so much so, that traces of the anti-depressant drug Prozac can be found in traces in the tap water.
Scientists have found the part of the brain where depression leaves an impact physically. Research carried out by the University of Warwick, UK, and Fudan University in China, have unearthed the physical root of depression.
According to the study data, depression is located in the non-reward center of the brain. Basically this is the part which is most affected by depression in a physical sense.
It has been found that head traumas cause brain transformations in youth who play football. The experts studied quantifiable brain changes in youth who played football. They clearly saw that the head butts they were often forced to engage in had wrought changes in the structures of their brains.
This effect appeared merely within a single season after playing football. Even if they apparently never suffered from a concussion or two, they nevertheless showed signs of changes in their brain tissue. This was for obvious reasons not a good sign.
There happen to be over 3 million youth members who are athletes in their own right and they practice tackle football across the United States. The risks of brain injury are said to exist and recent reports say that such is indeed the case.
