The brain is soft and squishy, like “a swollen network of gooey gel.” Electronics, on the other hand, tend to be rigid. So designing a brain implant can be tricky, like sticking a plastic fork into a bowl of Jell-O and hoping the fork doesn’t move too much. The first sensor was implanted into the brain of a paralyzed patient in 1998. The past 20 years have seen growing interest in brain-machine interfaces, which are brain implants that can record information from our neurons and also stimulate the neurons. Millions of dollars have been spent on developing this technology, from government-funded projects to Elon Musk’s startup NeuraLink. The possibilities are intriguing: help those with motor disabilities, treat depression, or, if you’re Musk, merge AI and human brains to replace language as we know it. The Verge spoke with Christopher Bettinger, a materials scientist and biomedical engineer at Carnegie Mellon University, about the state of brain-machine … [Read more...] about Why it’s so hard to develop the right material for brain implants
Pancreas what is its function
ORLANDO, Fla.--(BUSINESS WIRE)--Apr 26, 2018--Hesperos, Inc. has increased its pioneering human-on-a-chip drug testing capabilities by adding a new in vitro, human-human neuromuscular model to its patented multi-organ microfluidic device systems. Abnormal function of the neuromuscular junction is associated with neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy, and a human model will be critical in developing and selecting effective drugs to treat these diseases.This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20180426006161/en/(Graphic: Business Wire)The breakthrough technology is described in a recent Biomaterials paper by Hesperos CSO James Hickman from the Hybrid Systems Laboratory at the University of Central Florida, “ Stem cell derived phenotypic human neuromuscular junction model for dose response evaluation of therapeutics.” The technology is licensed to … [Read more...] about Human-on-a-chip Company Hesperos Licenses First Functional Stem-Cell Derived Neuromuscular Junction Model
The gallbladder is an organ that is part of the human biliary system, which is involved with the production, storage and transportation of bile. Bile is a yellowish-brown fluid produced by the liver and used to break up and digest fatty foods in the small intestine. The gallbladder is not absolutely necessary for human survival, as bile can reach the small intestine in other ways, according to Britain's National Health Service. Some problems associated with the gallbladder are gallstones, gallbladder attack and gallbladder disease. Gallbladder pain is usually caused by biliary colic, gallstones, cholecystitis, pancreatitis and cholangitis, according to MedicineNet. Gallstones Gallstones are somewhat common. In fact, up to 20 million Americans have gallstones, according to National Institute of Diabetes and Digestive and Kidney Diseases (NIDDKD). Only around 20 percent of these stones cause problems, though, according to the World Gastroenterology Organization. Gallstones are … [Read more...] about Gallbladder: Function, Problems & Healthy Diet
Fat is so often seen as the enemy — something to avoid or lose. But fat is also a crucial component of the body. Without it, humans would freeze. Our nerves, uninsulated, would jangle with crisscrossed communications. We'd be unable to store crucial supplies of certain vitamins, or have a functioning immune system. On a cellular level, fats make the membranes that surround cells possible and act as messengers that bind to proteins and enable various reactions. With that in mind, the humble fat cell seems a bit miraculous. Adipocytes, as they're properly known, are the cells that store excess lipids, the molecules that include fats and related substances. Adipocytes were once thought to be rather dull sacks of energy, but the past few decades of research have revealed that they have a lot to do in the body, from regulating nutrients to releasing hormones that influence blood pressure, thyroid function and even reproduction. [What Is Cellulite?] Anatomy of fat Under a … [Read more...] about What’s in a Fat Cell?
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system. According to the National Institutes of Health, the central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect to one another and to the central nervous system. Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component; and the autonomic, or involuntary, component. The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious effort, according to Merck Manuals. The somatic system consists of nerves that connect the brain … [Read more...] about Nervous System: Facts, Function & Diseases
