Brain Has Eyes Too – A sneak Peek Into Neurons

Yes, that is true. Nicknamed as ‘Jennifer Aniston’ a neuron based on the participant study which showed that one of the neuron of his brain lit up on recognizing the face of particular people like Jennifer Aniston or Hillary Clinton. So, this neuron was named after Jennifer Aniston. This report further revealed that one single specific cell lit up whenever a person’s certain conscious experience was concerned. This throws further light on the response of brain cells the relation of the activities with consciousness. Though, understanding the scope and science of human consciousness is a mystery that is yet to be unfolded and even researchers cannot say with surety if these neurons lead to conscious thoughts.

Brain Has Eyes Too - A sneak Peek Into Neurons

There were studies around the same carried out in 2008 which used a masking technique. This technique showed an image of a popular person like Aniston for 16 milliseconds immediately followed by a pattern Image muddling the face afterimage on the retina, thus making it rather hard for the brain to register what it saw. Later on in another study that used a method for hiding images from participants awareness. The phenomenon used for the experiment is called attentional blink wherein two target images are shown in a high speed streaming along with some other similar images. This results in a person often not able to recognize the second image targeted.

A similar study was carried out over a list of 21 patients under epilepsy and brains were fitted with special treatment electrodes. The trial included showing 14 different images predetermined by the scientist as familiar to the person. Further each one had a particular activity of specific brain cell. Now, when the trial was conducted, the researchers asked the participants to concentrate on two target images of the 14. All the images would later be flashed on the screen for 150 milliseconds. The medial temporal lobe was under constant monitoring during and after the trail and the researchers queried the participants if they had seen two images of familiar faces.

Every cell with unique signature was studied as it lit up and helped researchers link a brain cell pattern to particular images and had the ability to tell about the image represented even though
the participants are not aware of it.

Furthermore, research work is on as the researchers believe that they are at the intersection of perception and memory and investigation was needed to find out the results of direct stimulation of neurons.

Safe House For Many Disease Causing Viruses – Human Semen

Safe House For Many Disease Causing Viruses - Human Semen

When researchers was carried out on Zika virus, it was found that the virus finds its way through the man’s semen and stays there safely for a long time, over a few months. This led to a further study about other viruses with the ability to find their way to the man’s semen and staying there safely.

The research was carried out at the oxford university and it was discovered that there were a minimum of 27 different viruses with and ability to get into the blood and the semen as per the existing reports of scientific literature of ‘viremic’ viruses. The research also highlighted that the spread of the viruses in the semen is apparently even more than assumed.

The list of viruses not only includes lesser known ones but lots of popular ones too like HIV, Hepatitis C, Ebola, herpes, chikungunya, chickenpox and the less known ones like simian foamy, rift valley fever to name a few.
Though research is just at the preliminary stage as only the list of the viruses that have the ability to use a man’s semen as a safe house stay are known but more details like how long can they actually stay there, in what concentrations and how able they are in triggering or fueling he disease is yet to be studied.

Additionally, it is yet to be known whether these viruses have the ability to infect the sperms. This holds grave importance because it can lead to mutating the sperm DNA and passing the same to the next generation further increasing cancer risk in that generation as well. Additionally, many of us might not be aware that testes are known to be immune to any invasions by the body’s immune system. They are also therefore called immuno-logically privileged.

These findings might just raise questions on the considerations around treatments developed for viral diseases and their effects on the virus located across the body included the male reproductive tract.

Lower Back Pain vs Kidney Pain – The Difference

Many of us fail to figure out the difference when we experience pain particularly when its either kidney or lower back pain. So, to begin get down to the definition of lower back pain and kidney pain.

It’s called lower back pain when it occurs anywhere from the buttocks upto the lower back. While kidney pain is said to occur between the hips or flanks and the ribs. At times you may experience it in the upper abdominal region as well. Well, this is the basic difference in back pain and kidney pain but otherwise also there are many other difference that can help you figure out which kind of pain you are suffering from. Here’s a sneak peek into a few other differences between kidney pain and lower back pain.

LOWER BACK PAIN VS KIDNEY PAIN

Kidney Pain
Kidney pain is the result of a kidney infection or a kidney stone usually. Kidney infection can cause mild pain but kidney stone pain is very severe in nature and often compared to labor pain.

Causes
The causes of kidney pain include kidney infection and kidney stones as mentioned before besides the pain could also be a result of renal infarction, kidney cancer and glomerulonephritis.

Lower Back Pain
Lower back pain is further divided as acute pain and chronic pain. While acute pain lasts for around 4 to 12 weeks, chronic back pain can easily last over 12 weeks. Also known as lumbago it affects people of all age groups.

Causes
Lower back pain is a result of muscle sprain, spasm or tear leading to disc bulge or herniation, spinal stenosis, osteoporosis or sciatica. It could also be due to vertebral body, pedicle fracture or fracture of lamina. It can be caused due to Paravertebral muscle spasm or metastatic vertebral cancer.

Pain Management
Kidney Pain – Kidney pain treatment depends of its causes and usually involves use of antibiotics and medications if its infection but in case of kidney stones if that does not work a laser surgery or a minimally invasive surgery could be carried out.

Back Pain – For relief against lower back pain issues treatment could include suitable therapies like heat and cold, physical and massage therapies to name a few. In case with complications based on the diagnosis surgical procedures might be advised.

Well, its always advisable to visit your doctor if you suffer from back pain in order to figure out the root cause of the problem, be it kidney or lower back.

Artificial Limbs That Respond To Thoughts – A Reality That Costs A Fortune

Over the years, scientists have been working on prosthetic limbs that can respond to human thoughts. These projects have been heavily funded by many organizations and defense agencies across the world. A significant development in the direction has now led to the creation of the first ever prosthetic limb that responds to human thoughts much like a real limb.

Artificial Limbs That Respond To Thoughts

Earlier, there was news about creation of prosthetic limbs that respond to thoughts but their movement was quite limited and hence, people in need either abandoned them or never preferred to use them. But, as per the doctor of Imperial college London, the new approach which shifts their focus from the muscles to the nervous system has helped them create a limb that responds to thoughts effectively.

According to him, their technology helps them detect and decode the signals clearly. The experiments and testing have been carried out with amputee volunteers and after physiotherapy they have been able to make more extensive movements.

Today, a lot of research scientists are already working and testing bionic arms. There is already and alternative of using brain implants available. But, the benefit of using the nerve from the spine is the compatibility factor, making it usable with existing prosthetic arms that too wire free linking from the brain, as per the researchers at Imperial College of London.

Another example is that of a thought controlled prosthetic being developed at the John Hopkins University, USA. It is being tested on a 50 plus amputee who lost his limbs in an electrical accident as a teenager. It is yet to be clinically tested and find a place in the market. The limbs are called Modular Prosthetic Limbs or MPL and the customer socket inside brain can pick up brain signals that control the arms. Thus, just by thinking the amputee is able to move the limb or limbs. To do the same, the amputee had to undergo a surgery for remapping the remaining nerves of his/her missing arms so that the brain could send signals to the prosthetic. As per the chief engineer at John Hopkins, with the remapping growing deeper, the working will better because of the over 100 sensors fitted in the arm. Another advantage of MPL being its modular design. This design helps in creating prosthetic limbs customized as per individual requirements.

Having said that, as on day MPL costs a bomb, as much as a Maserati car to be precise. Well, scientists are yet to work on a budget prosthetic, affordable to people in need. experts at John Hopkins are also working on creating caps that send signals about brain activity to the robotic arm. As for the market availability, they do hope to make the MPL available to the consumers within a few years.
