The Limits of Neuroplasticity in the Brain
Posted by Nicholi Avery in categories: biological, neuroscience, science
New research shows that the brain‘s neuroplasticity isn’t as flexible as previously thought.
One of the brain’s mysteries is how exactly it reorganizes new #information as you learn new tasks. The standard to date was to test how neurons learned new behavior one #neuron at a time.
Carnegie Mellon University and the University of Pittsburgh decided to try a different approach. They looked at the population of neurons to see how they worked together while #learning a new behavior. Studying the intracortical population activity in the primary motor cortex of rhesus macaques during short-term learning in a brain–computer interface (BCI) task, they were able to study the reorganization of population during learning.

Aggregate form of α-synuclein leads to cell death in Parkinson’s Disease
Posted by Nicola Bagalà in categories: biotech/medical, neuroscience
An interaction between aggregate alpha synuclein and ATP synthase implicated in Parkinson’s Disease.
An open-access paper published in Nature Communications sheds light on how an accumulation of α-synuclein protein in brain cells contributes to causing Parkinson’s disease. In particular, the researchers discovered how clumps of the protein damage important proteins on mitochondrial surfaces, leading to impaired energy production, swelling and bursting of the mitochondria themselves, and, ultimately, cell death [1].

A Neuroscientist Explains What Happens to Your Brain When You Don’t Sleep
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
Sleep deprivation affects nearly all parts of your brain, but it is most detrimental to simple cognitive functions that we take for granted, such as memory and staying alert.
Ph.D. neuroscience candidate Shannon Odell says scientific research suggests that sleep deprivation majorly reduces cognitive performance. Studies have shown that patients have significantly reduced their thinking ability after just one night of sleep deprivation, specifically in the hippocampus, also known as the memory center.

Never miss a talk! SUBSCRIBE to the TEDx channel: http://bit.ly/1FAg8hB
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

‘Smile, it’s the Future!’ — Emotions, Mixed Reality, and Techno-Telepathy
Posted by B.J. Murphy in categories: augmented reality, neuroscience
Let me propose a hypothetical future scenario: Let’s say that we’ve since developed an advanced method of brain-to-brain (B2B) communication, to which, naturally, has become quite popular among the younger generation of that time.
How might we judge futuristic societies using our present day standards? Better yet, how might the past have judged us today and would there be a difference?

Probiotics may help boost mood and cognitive function
Posted by Nicholi Avery in categories: biotech/medical, health, neuroscience
Probiotics can do more than improve your gut health. They also may indirectly enhance your brain, too.
Research shows that the gut and brain are connected, a partnership called the gut-brain axis. The two are linked through biochemical signaling between the nervous system in the digestive tract, called the enteric nervous system, and the central nervous system, which includes the brain. The primary information connection between the brain and gut is the vagus nerve, the longest nerve in the body.
The gut has been called a “second brain” because it produces many of the same neurotransmitters as the brain does, like serotonin, dopamine, and gamma-aminobutyric acid, all of which play a key role in regulating mood. In fact, it is estimated that 90% of serotonin is made in the digestive tract.

When Healthcare ignores Mental Health: 200 common prescription medications increase depression risk
Posted by Alvaro Fernandez in categories: biotech/medical, health, neuroscience
Why is no one talking about this? — “More than one-third of U.S. adults are taking prescription medications that may lead to depression, new research finds. The study, published in the Journal of the American Medical Association, warns that depression is a potential side effect of more than 200 commonly prescribed medications, including beta blockers for blood pressure, birth control pills, antacids, and painkillers.”

In case we needed more evidence that staying fit is good for you…
A study to be published in the Journal of Alzheimer’s Disease shows a correlation between low fitness, aortic stiffness, and the cognitive decline typically observed during brain aging [1].
