Remote control for brain cells: scientists use ultrasound waves to activate neurons

Posted by in categories: biotech/medical, neuroscience

Some treatments for neurodegenerative diseases involve inserting wires into the brain and zapping certain brain cells with electricity. But what if you could do the same thing using sound waves?

Smart drugs: All-natural brain enhancers made by mother nature

Posted by in categories: biotech/medical, neuroscience

Nootropics are colloquially known as “smart drugs” – substances that increase cognitive function in healthy people. In this video, bestselling author Dave Asprey discusses two naturally occurring nootropics: caffeine and nicotine.

Microdosing one milligram of the latter — about 5 to 10 percent of a cigarette’s worth — may even protect against Alzheimer’s.

New MRI technique captures image of a brain thinking

Posted by in categories: bioengineering, biotech/medical, neuroscience

An international team of researchers with partial support from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) developed a new MRI technique that can capture an image of a brain thinking by measuring changes in tissue stiffness. The results show that brain function can be tracked on a time scale of 100 milliseconds – 60 times faster than previous methods. The technique could shed new light on altered neuronal activity in brain diseases.

The human brain responds almost immediately to stimuli, but non-invasive imaging techniques haven’t been able to keep pace with the brain. Currently, several non-invasive brain imaging methods measure brain function, but they all have limitations. Most commonly, clinicians and researchers use functional magnetic resonance imaging (fMRI) to measure brain activity via fluctuations in blood oxygen levels. However, a lot of vital brain activity information is lost using fMRI because blood oxygen levels take about six seconds to respond to a stimulus.

Since the mid-1990s, researchers have been able to generate maps of tissue stiffness using an MRI scanner, with a non-invasive technique called magnetic resonance elastography (MRE). Tissue stiffness can’t be measured directly, so instead researchers use MRE to measure the speed at which mechanical vibrations travel through tissue. Vibrations move faster through stiffer tissues, while vibrations travel through softer tissue more slowly; therefore, tissue stiffness can be determined. MRE is most commonly used to detect the hardening of liver tissue but has more recently been applied to other tissues like the brain.

The World’s First MRI of a SINGLE Atom Is Here, and It Could Revolutionize Imaging

Posted by in categories: computing, neuroscience, quantum physics

Magnetic resonance imaging is nothing new, but scientists were able to perform an MRI on a single atom. But how?

‘Key player’ identified in genetic link to psychiatric conditions

Posted by in categories: genetics, health, neuroscience

Scientists have identified a specific gene they believe could be a key player in the changes in brain structure seen in several psychiatric conditions, such as schizophrenia and autism.

The team from Cardiff University’s Neuroscience and Mental Health Research Institute has found that the deletion of the gene CYFIP1 leads to thinning of the insulation that covers and is vital for the smooth and rapid communications between different parts of the .

The new findings, published in the journal Nature Communications and highlighted in the journal Nature Reviews Neuroscience, throws new light on the potential cause of and could ultimately point to new and more effective therapies.

Brain scans could help personalize treatment for people who are depressed or suicidal

Posted by in categories: biotech/medical, habitats, neuroscience

By his late 20s, Moe had attained the young adult dream. A technology job paid for his studio apartment just blocks from the beach in Santa Barbara, California. Leisure time was crowded with close friends and hobbies, such as playing the guitar. He had even earned his pilot’s license. “There was nothing I could have complained about,” he says.

Yet Moe soon began a slide he couldn’t control. Insomnia struck, along with panic attacks. As the mild depression he’d experienced since childhood deepened, Moe’s life collapsed. He lost his job, abandoned his interests, and withdrew from his friends. “I lost the emotions that made me feel human,” Moe says. (He asked that this story not use his full name.)

Although many people with depression respond well to treatment, Moe wasn’t one of them. Now 37, he has tried antidepressant drugs and cycled through years of therapy. Moe has never attempted suicide, but he falls into a high-risk group: Though most people with depression don’t die by suicide, about 30% of those who don’t respond to multiple antidepressant drugs or therapy make at least one attempt. Moe was desperate for relief and fearful for his future. So when he heard about a clinical trial testing a new approach to treating depression at Stanford University in Palo Alto, California, near his home, he signed up.
