Learn How Scientists are Decoding the Most Complex Object in the Universe: The Brain

Researchers from University College London (UCL) are working on a project with the lofty goal of analyzing the entirety of a brain’s neuronal activity in real time. Most estimates place the number of neurons in the average brain somewhere between 70 and 100 billion. Trying to record all of the relevant activity in one brain as it occurs will be difficult enough, but beyond that, the UCL team is planning to employ considerable processing power towards deciphering the meaning of each firing synapse. NeuroPixels, as the prototype probes are being called, are the width of a human hair and can monitor hundreds of neurons at once over multiple regions of the brain while simultaneously digitizing the signal on-board and sending the information to a database. Developed in collaboration with a consortium of leading non-profit organizations in neuroscience, these super-sensitive electrode sensors are already being studied in mice models, and are expected to be available for purchase by research labs in mid-2018. The researchers are already in the process of developing the next generations of these sensors. Click here to read more about this technology on the UCL News Outlet. Rafael Yuste, MD, PhD, Professor of Neuroscience at Columbia University, discusses the research goals of the brain activity map project. He explains the purpose of this ground breaking research is to develop tools that will allow scientists of the future to measure the activity of every neuron in the brain. The Brain Activity...

Why I Didn’t Do Research

You may or may not be aware from reading my prior writings that for a time, I was considering a career in research. I worked in labs during every summer through college, and even though I didn’t do any research during med school and not a whole lot during residency, I actually ended up doing a research fellowship. Also, I have research in my blood. My father is a physician who gets a chunk of his salary from research grants. My mother didn’t go quite so far as that, but did publish around a hundred peer-reviewed articles during her career. My father especially encouraged me to incorporate research into my career, saying that it was interesting and also provided extra career flexibility. So anyway, I did this fellowship. And it sucked. I mean, it was pretty much The Fellowship Where Everything Went Wrong. I know what you’re thinking, that it’s not possible for a research fellowship to go that badly. Well, what if your research mentor is arrested and goes to jail midway through the year? I’m not saying that happened. But I’m not saying that didn’t happen either. Bad fellowship aside, I did get a taste of what it was like to do research. There were some parts of it I liked very much. For example, I really liked when the article I wrote came out, and I...

How To Avoid Winter Depression

Seasonal Affective Disorder (SAD) is a type of depression, often known as Winter Depression, that comes and goes in a seasonal pattern. The symptoms are more apparent and tend to be more severe during the winter, often beginning in autumn and lasting throughout the darker months. Some sufferers may feel the effects right up until the weather improves and days become lighter in the spring. The symptoms can include a persistent low mood, lack of energy, loss of interest in every day tasks, sleeping for longer than normal and finding it difficult to get up in the morning, irritability, a tendency to over-eat or under-eat and social withdrawal. Although the symptoms can vary in severity, they can greatly impact day-to-day activities and have a real effect on the sufferer’s life.   Aside from the different forms of counseling such as Mindfulness Therapy, Cognitive Behavioral Therapy, and the use of light therapy to simulate light within your own home and reduce the negative effects that darker days can have. Within everyday routines it is important to maintain a healthy diet and add in elements such as complex carbs and Omega-3 to sustain energy levels and to boost mood. Overall it’s essential for sufferers to remember that they are not alone and there are strategies to take to relive symptoms. Mattress Online have looked into the treatment and prevention of SAD...

The Dark Side of Blood Thinners: What Side Effects Can the Drugs Cause?

What are blood thinners you may ask? They are a type of medication, formulated to keep one’s blood from clotting or prevent an existing clot from increasing in size. In that, it can either be antiplatelet or anticoagulant. Each form of drug works differently from the other. For instance, an antiplatelet, e.g., aspirin, blocks the release of thromboxane. It is a hormone that initiates clumping of the blood, which may result in clotting. On the other hand, anticoagulants, interfere with the production of proteins, in the blood. If you are given blood thinner prescription, you should take caution by sticking to it just as you would to the guidelines of a nursing personal statement. Situations where your doctor may prescribe a blood thinner include: • To reduce the risk of blood clots after a surgery • People with congenital heart defect • Those that suffer from valve or heart diseases • If you had a replacement of a heart valve Side Effects of Blood Thinners When used in the correct dosage, blood thinners are effective in preventing blood from clotting. A blood clot can lead to life-threatening blockages, heart attacks, and even strokes. However, blood thinners also come with side effects and risks, such as: a. Prolonged bleeding If you are taking blood thinners and by an unfortunate event, get wounded, a minor wound, wound would take some time...

How This Hospital Used A $10 Microchip to Produce 3D Ultrasound Models

Joshua Broder, MD, associate professor of surgery at Duke Health, is helping to lead a team of physicians and engineers in an effort to improve the information captured by 2D ultrasound machines. The team has developed software that couples with a simple 3D-printed case attachment and a $10 sensor chip to convert 2D image slices into a contextual 3D ultrasound model. This technology would allow existing 2D machine owners to maintain the portability and ease of use of their imaging units while greatly increasing the usefulness of the image outputs. Dr. Broder hopes the technology will advance enough to one day allow patients to use a similar device on themselves with enough accuracy to eliminate the need for a trip to an office or hospital. Click here to read more about this research on Health Imaging: “With 2D technology you see a visual slice of an organ, but without any context, you can make mistakes,” said Joshua Broder, MD, an associate professor of surgery at Duke Health and one of the creators of the technology. “These are problems that can be solved with the added orientation and holistic context of 3D technology. Gaining that ability at an incredibly low cost by taking existing machines and upgrading them seemed like the best solution to us.” “With trauma patients in the emergency department, we face a dilemma,” Broder said. “Do we take them...

Human World Records: The Greatest Achievements of the Human Body

Every year, thousands of people around the world submit their entry for a new world record. From the world’s longest fingernails to the most pints of beer drank in under 5 minutes, many of them show what the human body is capable of when it’s taken to extremes. For many of these people, it is a case of pushing the limits of the human body and mind. Mental barriers and physical hurdles are overcome. When signals are sent from the brain saying “stop”, they break through those, exercising incredible willpower and pushing beyond what they know is capable, breaking records time and again. There have been incredible feats of bravery and endurance. However, pushing mind and body to the limit isn’t everyone’s cup of tea. The challenge though, is to many, addictive and the sense of achievement once the goal is completed gives them unparalleled satisfaction. The “three needs” theory breaks motivation into three, arguing that motivation can be sliced into three: People push forward for achievement, for power and for belonging. This is certainly the case when the goal is more obscure or niche. They may be the only one striving for this goal and pursuing something against the advice of others. As humans, we strive to grow faster and stronger. To say, “what’s next?” and move forward. We enhance our capabilities every day and we all have...
