Fart gas may help prevent dementia, heart disease: study
Posted by Manuel Canovas Lechuga in categories: biotech/medical, health, neuroscience
Farts may stink to high heaven, but a new study suggests that the gas responsible for that foul odor may actually extend a person’s time on earth.
Scientists in the UK claim that hydrogen sulfide, the stinky compound that smells like rotten eggs which contributes to the flatulence stench, could have amazing health benefits.
Hydrogen sulfide can be toxic, but tiny amounts have been shown to help protect the mitochondria, which are known as the “powerhouses” of cells.

Ageing-related receptors resolved
Posted by Manuel Canovas Lechuga in categories: biotech/medical, life extension, neuroscience
Klotho is a membrane-spanning protein expressed predominantly in the kidney, as well as in the brain.
Ageing is a regulated process in which hormones have pivotal roles. Crystal structures of two hormone co-receptors should be informative for drug discovery focused on age-related disorders.

Memory Successfully Boosted In Humans
Posted by Marcos Than Esponda in categories: biotech/medical, cyborgs, mathematics, neuroscience
Scientists from Wake Forest Baptist Medical Center partnered with researchers from the University of Southern California to develop an innovative procedure to give hope to people struggling with remembering important information. A new implant uses a person’s own memory patterns in order to boost the brain’s natural ability to encode those memories and recall them quickly. There has been a reported 35 to 37 % increase in short-term memory performance.
“This is the first time scientists have been able to identify a patient’s own brain cell code or pattern for memory and, in essence, ‘write in’ that code to make existing memory work better, an important first step in potentially restoring memory loss,” said the study’s lead author Robert Hampson, Ph.D., professor of physiology/pharmacology and neurology at Wake Forest Baptist.
Epilepsy patients from Wake Forest Baptist were surgically implanted with electrodes in the various parts of their brains. The electronic prosthetic system is based on a multi-input-multi-output (or MIMO) mathematical model to influence the patterns of neurons firing within the hippocampus.

Brain adapts after rare dementia attacks language center
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
People with a rare kind of dementia that initially attacks the language center of the brain end up recruiting other areas of the brain to decipher sentences, according to a new study.
The study is one of the first to show that people with a neurodegenerative disease can call upon intact areas of the brain for help. People who have had strokes or traumatic brain injuries sometimes use additional regions of the brain to accomplish tasks that were handled by the now-injured part.
“We were able to identify regions of the brain that allowed the patients to compensate for the dying of neurons in the brain,” says first author Aneta Kielar, an assistant professor of speech, language, and hearing sciences and of cognitive science at the University of Arizona.

Video Gaming as a Geroprotective Strategy
Posted by Steve Hill in categories: entertainment, health, neuroscience
Contrary to certain sensationalist articles declaring that video games are harmful, there is, in fact, growing evidence that playing video games may have a positive effect on cognitive health, particularly in older people [1].
Today, we will be taking a look at the scientific evidence to see if brain training or hitting your favorite video game titles could help keep you healthy as you age.

Brain implants put paralyzed man back in touch with himself
Posted by Genevieve Klien in categories: biotech/medical, cyborgs, neuroscience
Researchers at Caltech have induced a range of sensations in the arm of a paralyzed man. The breakthrough comes courtesy of electrodes implanted in the brain, which stimulated the neurons to produce different feelings depending on the type of electrical signals. The team says the research could eventually lead to advanced prosthetic limbs that allow users to feel realistic sensations through them.
Plenty of exciting research is being conducted to help paralyzed people regain control of and feeling in their limbs. The NeuroLife system has helped a quadriplegic man move his arms again using just his thoughts, allowing him to perform a number of actions. Electrical nerve stimulation, both with and without electrode implants, has helped several people voluntarily move their legs again, often for the first time in years.
In this new study, Caltech researchers implanted two tiny arrays of electrodes into the somatosensory cortex, the small region of the brain responsible for the body’s sensations of movement or position, as well as cutaneous sensations such as touch, pressure and vibration.
