Scientists Have Connected The Brains of 3 People, Enabling Them to Share Thoughts

Cientistas conectaram o cérebro de 3 pessoas, permitindo que elas compartilhassem os pensamentos! smile
Neuroscientists have successfully hooked up a three-way brain connection to allow three people share their thoughts – and in this case, play a Tetris-style game. The team thinks this wild experiment could be scaled up to connect whole networks of people, and yes, it’s as weird as it sounds.
It works through a combination of electroencephalograms (EEGs), for recording the electrical impulses that indicate brain activity, and transcranial magnetic stimulation (TMS), where neurons are stimulated using magnetic fields.

The Next Social Networks Could Be Brain-to-Brain
Posted by Mike Ruban in categories: neuroscience, physics, space
It might already feel like social media is taking up too much of our mental space, but just wait until it’s literally inside of our brains.
Physicists and neuroscientists have developed the world’s first “brain-to-brain” network, using electroencephalograms (EEGs), which record electrical activity in the brain, and transcranial magnetic stimulation (TMS), which can transmit information into the brain, to allow people to communicate directly with each other’s brains — a new and thrilling (and a little terrifying?) example of science fiction brought to life.
Researchers at the University of Washington in Seattle announced last week that they successfully used their interface, which they call BrainNet, to have a small group of people play a collaborative “Tetris-like” game — with their minds.

Your Environment Could Be Changing Your IQ on a Genetic Level, Study Finds
Posted by Xavier Rosseel in categories: genetics, neuroscience
Be gone flat earthism.
The nature-versus-nurture argument of intelligence just got a lot more complicated with the discovery that the environment can modify the expression of a key gene in the brain, affecting intelligence far more than we previously thought.
Such a finding may not come as a surprise if you remember that numerous genes influence our IQ and stressful experiences can lock and unlock genes in our brains. Yet having hard evidence of the link will no doubt stir debate on just what it means to be “smart”.

The mathematics of mind-time
The special trick of consciousness is being able to project action and time into a range of possible futures.

NIH ACD BRAIN Initiative Working Group 2.0 Workshop 2
Posted by Mike Ruban in categories: biotech/medical, neuroscience
Perhaps you read the stories last week (including the NYT piece linked to below) about the researchers at Johns Hopkins, led by Gul Dolen, who gave ecstasy (MDMA) to octopuses and found that they, like humans, became more social on the drug. Dr. Dolen talked about using the octopus as a model organism in neuroscience research during last Friday’s day-long workshop hosted by the NIH BRAIN 2.0 working group.
By dosing the tentacled creatures with MDMA, researchers found they share parts of an ancient messaging system involved in social behaviors with humans.

The first “social network” of brains lets three people transmit thoughts to each other’s heads
Posted by Mike Ruban in category: neuroscience
BrainNet allows collaborative problem-solving using direct brain-to-brain communication. The ability to send thoughts directly to another person’s brain is the stuff of science fiction. At least, it used to be.

Brain Implants Would End Most Sexual Assaults

Some of my thoughts on the Kavanaugh hearings, sexual assault, and technology: https://mavenroundtable.io/…/brain-implants-would-end-most…/ #transhumanism #MeToo
A brain implant that registers trauma could help prevent rape and violent crime — so why don’t we have it yet?

Gut sense: Neural superhighway conveys messages from gut to brain in milliseconds
Posted by Xavier Rosseel in category: neuroscience
Searching for a more direct connection between the gut and the brain, researchers were shocked to see that distance spanned by a single synapse, relaying the signal in less than 100 milliseconds, less than the blink of an eye. The finding has profound implications for the understanding of appetite and appetite suppressants, most of which target slow-acting hormones rather than fast-acting synapses.

Can genetic tests gauge how well antidepressants will work?
Posted by Genevieve Klien in categories: genetics, health, neuroscience
With the introduction of more products aimed at gauging the effectiveness of mental health treatments, science is getting left behind, some experts say.
