How to cope with anxiety: Olivia Remes

Posted by in categories: health, neuroscience

Anxiety is one of most prevalent mental health disorders, with 1 out of 14 people around the world being likely affected. Leading up to conditions such as depression, increased risk for suicide, disability and requirement of high health services, very few people who often need treatment actually receive it…

In her talk “How to cope with anxiety”, Olivia Remes of the University of Cambridge will share her vision on anxiety and will unravel ways to treat and manage this health disorder. Arguing that treatments such as psychotherapy and medication exist and often result in poor outcome and high rates of relapses, she will emphasise the importance of harnessing strength in ourselves as we modify our problem-coping mechanisms.

While sugar impairs memory and learning skills, eating chocolate improves brain function

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

Researchers at UCLA (University of California, Los Angeles) conducted a study in 2012 on rats and found that a diet high in fructose hinders learning skills and memory and also slow down the brain. The researchers found that rats who over-consumed fructose had damaged synaptic activity in the brain, meaning that communication among brain cells was impaired.

Study’s lead author Dr. Fernando Gomez-Pinilla said in a statement that “Insulin is important in the body for controlling blood sugar, but it may play a different role in the brain. Our study shows that a high-fructose diet harms the brain as well as the body.”

Scientists use magnetic fields to remotely stimulate brain — and control body movements

Posted by in categories: biotech/medical, neuroscience

Scientists have used magnetism to activate tiny groups of cells in the brain, inducing bodily movements that include running, rotating and losing control of the extremities — an achievement that could lead to advances in studying and treating neurological disease.

Scientists Are Finally Set to Mass-Produce The Active Compound Found in Magic Mushrooms

Posted by in categories: chemistry, neuroscience

For nearly 60 years scientists have known the chemical responsible for magic mushrooms’ psychedelic reputation is a compound called psilocybin. What we haven’t known is the biochemical pathway behind this famous hallucinogen.

Feel free to now tick that one off your chemistry bucket-list. German researchers have identified four key enzymes involved in making the chemical, potentially setting the stage for mass production of a promising pharmaceutical.

Psilocybin was first identified by the Swiss scientist Albert Hofmann way back in 1959, but has only recently re-entered the spotlight as a safe way to treat conditions related to anxiety, depression, and addiction.

Specialized Neurons That Respond to Pain of Pulling Single Hair Discovered

Posted by in categories: health, neuroscience

Summary: NIH researchers have identified a specific type of sensory neurons which become activated as a result of pulling a single hair.

Source: NIH.

Researchers from the National Institutes of Health have identified a class of sensory neurons (nerve cells that electrically send and receive messages between the body and brain) that can be activated by stimuli as precise as the pulling of a single hair. Understanding basic mechanisms underlying these different types of responses will be an important step toward the rational design of new approaches to pain therapy. The findings were published in the journal Neuron.

The Adult Brain Can Regenerate Neurons in an Unexpected Area, Says New Study

Posted by in categories: health, neuroscience

Scientists have discovered for the first time that adult mouse brains produce new cells in the amygdala, a finding that could eventually lead to better treatments for conditions like anxiety and depression, as well as a better understanding of the brain overall.

The amygdala handles a lot of our emotional responses, especially those relating to fear, and broken connections inside it can lead to anxiety disorders such as post-traumatic stress disorder (PTSD).

If the brain is capable of regenerating neurons in the amygdala, then that’s potentially one way of fighting back against these mental health issues, according to the team from the University of Queensland in Australia.

Scientists remotely hacked a brain, controlling body movements

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

Imagine someone remotely controlling your brain, forcing your body’s central processing organ to send messages to your muscles that you didn’t authorize. It’s an incredibly scary thought, but scientists have managed to accomplish this science fiction nightmare for real, albeit on a much small scale, and they were even able to prompt their test subject to run, freeze in place, or even completely lose control over their limbs. Thankfully, the research will be used for good rather than evil… for now.

The effort, led by physics professor Arnd Pralle, PhD, of the University at Buffalo College of Arts and Sciences, focused on a technique called “magneto-thermal stimulation.” It’s not exactly a simple process — it requires the implantation of specially built DNA strands and nanoparticles which attach to specific neurons — but once the minimally invasive procedure is over, the brain can be remotely controlled via an alternating magnetic field. When those magnetic inputs are applied, the particles heat up, causing the neurons to fire.

Shocking Data Analytics & Mind Control of the Future

Posted by in categories: futurism, neuroscience

If Data Analytics and Analysis is being used today to predict and control what we purchase, what we spend our time on and how we vote in political elections, what are its future uses?

This technology will only become more powerful and accurate over time.

New Tech Is Giving Humanity Many Potential Paths to Immortality

Posted by in categories: life extension, neuroscience, Ray Kurzweil, singularity

Both Kurzweil and the 2045 program have predicted the state of machine-human singularity being achieved by 2045, but what are the methods of achieving such an end and what are the consequences of doing so?

Herodotus’s Fountain of Youth. Rowling’s Philosopher’s Stone. Barrie’s Neverland. Ovid’s Cumaean Sibyl. The idea of immortality has been ingrained in humanity’s creative consciousness since our humble beginnings. In the present day, eternal youth may soon move out of the realms of myth and into a reality thanks to developing technologies.
