Does Zapping Your Brain Actually Help You Learn Faster?

From time to time, the Singularity Hub editorial team unearths a gem from the archives and wants to share it all over again. It’s usually a piece that was popular back then and we think is still relevant now. This is one of those articles. It was originally published March 6, 2016. We hope you enjoy […]

This Neural Probe Is So Thin, The Brain Doesn’t Know It’s There

Wiring our brains up to computers could have a host of exciting applications – from controlling robotic prosthetics with our minds to restoring sight by feeding camera feeds directly into the vision center of our brains. Most brain-computer interface research to date has been conducted using electroencephalography (EEG) where electrodes are placed on the scalp […]

Can Dead Brains Be Brought Back to Life? First Human Study to Find Out

Last month, a Philadelphia-based biotech company kicked off a clinical trial that pushes the envelope of what it means to be dead. Armed with ethical approval from the IRB at the Anupam Hospital in India, Bioquark is recruiting 20 patients who have been clinically deemed brain dead from severe traumatic brain injury. With an arsenal of cutting-edge, if mysterious, treatment techniques — stem cells, bioactive molecules, brain and spinal cord stimulation — the team hopes to revive parts of the patients’ basic brain functions, with the eventual “holy grail” goal of returning the ability to breathe on their own. The… read more

How the Power to Control Objects With Our Minds Stopped Being Science Fiction

The recent announcement that a young paralysed man in Ohio in the US named Ian Burkhart managed to regain the use of his fingers after having a chip implanted in his brain is an exciting step forward for science and healthcare. In fact, you may now be wondering how long it will be before we can unlock a door, turn on a kettle, or even send an email simply by thinking about it? The Ohio breakthrough used a technique called functional magnetic resonance imaging (fMRI) to identify the pattern of electrical impulses in the part of the brain that controls… read more

Can You Download Knowledge Into Your Brain With Electricity?

A cognitive neuroscientist and his team at HRL Laboratories in Malibu, California, seem to have achieved the impossible. According to a press release, the team “measured the brain activity patterns of six commercial and military pilots, and then transmitted these patterns into novice subjects as they learned to pilot an airplane in a realistic flight simulator.” If you’re picturing people downloading knowledge directly into the brain Matrix-style, sorry to hand you the blue pill — it’s utter nonsense. Which is a total shame, because the brain-boosting technique used in the study — transcranial direct current stimulation, or tDCS, is nothing… read more

Watch Monkeys Drive Wheelchairs With Just Their Thoughts

Duke University scientists have given a pair of monkeys the ability to drive a wheelchair with their thoughts alone. The work is described in a paper recently published in the journal Scientific Reports and adds to a growing body of work in brain-machine interfaces aiming to return some freedom to the severely disabled. Duke neuroscientist Miguel Nicolelis and his team first began experimenting back in 2012, when they implanted hundreds of microfibers as thin as a human hair in the brains of two rhesus macaque monkeys. The fibers recorded cortical activity associated with “whole-body movement” and sent the signals to a computer…. read more

Playing 20 Questions by ‘Telepathy’? Big Score for Brain-to-Brain Communication

Interpersonal communication just got a lot more intimate. So intimate, in fact, that two strangers — physically separated by a mile — can literally get into each other’s heads to… read more
