Using Music To Boost Hearing In Noisy Environments. Most of the people in a choir at Ryerson University in Toronto have joined a study testing how practicing music might help people with hearing loss handle noisy environments better.

Creative people physically see and process the world differently

People who are open to new experiences can take in more visual information than other people and combine it in unique ways. This may explain why they tend to be particularly creative. Neuralink and the Brain's Magical Future. Terry Jones: ‘I’ve got dementia. My frontal lobe has absconded’ Terry Jones first exhibited signs that all was not well with his health in July 2014.

Terry Jones: ‘I’ve got dementia. My frontal lobe has absconded’

He and his close friend Michael Palin were performing with the rest of the surviving Monty Python’s Flying Circus troupe in a show of sketches and songs, Monty Python live (mostly) at the O2 in London. “Terry was always very good at remembering lines,” recalled Palin last week. MIT's Super-Thin Wires Are Leading to a New Age in Brain Implants. One Device to Transmit Them All Brain research has often relied on devices that manipulate electrical, chemical, or optical signals separately.

MIT's Super-Thin Wires Are Leading to a New Age in Brain Implants

Combining these was usually “somewhat probabilisitic,” according to Polina Anikeeva, one of the more than a dozen researchers from the Massachusetts Institute of Technology (MIT) and elsewhere involved in the study. “We said, wouldn’t it be nice if we had a device that could just do it all.” The result was an optogenetic device that uses fibers just about 200 micrometers across, designed to mimic the flexibility of brain tissue. UNIT 1: Sensory Receptors. Neuroscientists Discover an Ignition Switch for Consciousness. What's the Latest?

Neuroscientists Discover an Ignition Switch for Consciousness

When Francis Crick, the English scientist who helped discover the structure of DNA, died in 2004, he and a colleague were in the midst of researching the potential existence of an on-off switch for consciousness located somewhere deep within the brain. Crick's hypothesis likened the proposed switch to an orchestra conductor "to bind all of our different external and internal perceptions together. " Researchers at George Washington University in Washington DC believe they may have found Crick's conductor. Scientists Attempt to Reanimate the Brain Dead. What are the Implications? Imagine this, your loved one gets into a serious accident.

Scientists Attempt to Reanimate the Brain Dead. What are the Implications?

You and your family gather at the hospital. In the I.C.U. the doctor makes a grim announcement, they‘re brain dead. How hormones work. Scientists Unveil a New Map of the Brain With Unrivaled Resolution. In Brief The Allen Institute for Brain Science has published and released a comprehensive, high-resolution map of the brain anyone can access online.

Scientists Unveil a New Map of the Brain With Unrivaled Resolution

They mapped 862 brain structures from a single donor brain. Been Traumatized? Here's How PTSD Rewires the Brain. We tend to float about our lives, worrying about little inconveniences.

Been Traumatized? Here's How PTSD Rewires the Brain

But if the space inside your head is generally a peaceful one, count yourself lucky indeed. If instead, you are wrestling in the aftermath of some terrible trauma, it might seem like you’re the only one, but you are far from alone. What brain mapping hopes to accomplish. We’ve mapped the human genome, tread on every last bit of earth, landed on the moon and plunged the oceans.

What brain mapping hopes to accomplish

There are few untrammeled frontiers left, aside from space and the human brain. It is a touch ironic that that which makes us who we are, which has been with us from the very beginning, is one of the biggest mysteries to humanity. There’s little wonder. The human brain is comprised of 80 billion neurons, not to mention the oodles of support cells it needs to function. Neuroscientists aren’t even sure how many different types of brain cells there are. Human Connectome Project. Updated Brain Map Identifies Nearly 100 New Regions. The first hints of the brain’s hidden geography emerged more than 150 years ago.

Updated Brain Map Identifies Nearly 100 New Regions

In the 1860s, the physician Pierre Paul Broca was intrigued by two of his patients who were unable to speak. After they died, Broca examined their brains. On the outer layer, called the cortex, he found that both had suffered damage to the same patch of tissue. That region came to be known as Broca’s area. In recent decades, scientists have found that it becomes active when people speak and when they try to understand the speech of other people. Photo. Why Aspirin May be the Most Powerful Weapon in the War on Brain Cancer.

Less than 20 percent of people with brain cancer survive more than five years after their diagnosis. It’s one of the most deadly forms of cancer because there are very few treatments for it available. The brain-blood barrier is a massive hurdle because it prevents powerful cancer drugs such as chemotherapy from reaching cancerous tumors. VS Ramachandran: The neurons that shaped civilization. How your brain constructs reality. If We’re Going to Talk About Brainwaves, We Should Know What They Are. Brainwaves come up in conversation a lot, especially when you’re talking about mindfulness, creativity, falling asleep, and other processes we’re trying to understand. But do you know what a brainwave actually is? It’s kind of surprising.

Most of us have heard about at least some of these major brainwave categories (there are sub-categories, too): gamma brainwaves — 40 to 100 cycles, or Hertz (Hz) per second, associated with learning memory, and information processingbeta brainwaves — 12 to 40 Hz, associated with conscious thought and logical thinkingalpha brainwaves — 8 to 12 Hz, associated with light daydreaming and relaxationtheta brainwaves — 4 to 8 Hz, associated with deeper daydreaming and sleepdelta brainwaves — 0 to 4 Hz, associated with deep relaxation and restorative deep sleep, also with unconscious body functions ZEISS, a rat neuron An electroencephalogram, or EEG, can measure this electricity through electrodes temporarily stuck to a subject’s scalp. The Unfixed Brain. The brain dictionary. New cryopreservation procedure wins Brain Preservation Prize.

Lihong Wang uses light and sound to create highly detailed images of the living brain. Chris Nickels for NPR hide caption toggle caption Chris Nickels for NPR Lihong Wang uses light and sound to create highly detailed images of the living brain.

Chris Nickels for NPR Lihong Wang creates the sort of medical technology you'd expect to find on the starship Enterprise. Wang, a professor of biomedical engineering at Washington University in St. "It's really about turning some of these ideas that we thought were science fiction into fact," says Richard Conroy, who directs the Division of Applied Science & Technology at the National Institute of Biomedical Imaging and Bioengineering. Researchers show that memories reside in specific brain cells. Our fond or fearful memories — that first kiss or a bump in the night — leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the sensations of the experience. Neuroscientists call these traces memory engrams.

But are engrams conceptual, or are they a physical network of neurons in the brain? In a new MIT study, researchers used optogenetics to show that memories really do reside in very specific brain cells, and that simply activating a tiny fraction of brain cells can recall an entire memory — explaining, for example, how Marcel Proust could recapitulate his childhood from the aroma of a once-beloved madeleine cookie. In that famous surgery, Penfield treated epilepsy patients by scooping out parts of the brain where seizures originated.

Fast forward to the introduction, seven years ago, of optogenetics, which can stimulate neurons that are genetically modified to express light-activated proteins. This Nifty Infographic is a Great Introduction to Neuroplasticity and Cognitive Therapy. 20 Amazing Facts About Your Brain. Controlling RNA in living cells. MIT researchers have devised a new set of proteins that can be customized to bind arbitrary RNA sequences, making it possible to image RNA inside living cells, monitor what a particular RNA strand is doing, and even control RNA activity. The new strategy is based on human RNA-binding proteins that normally help guide embryonic development. Brain Information, Facts. Making sense of the brain's mind-boggling complexity isn't easy.
