Adult Human Brains Don’t Grow New Neurons in Hippocampus
By Shawn Sorrells, Arturo Alvarez-Buylla, Mercedes Paredes
12 March 2018
When our recent study met significant skepticism, we weren’t surprised. After all, we ourselves remained skeptical of what we were seeing throughout our investigation. But repeated and varied experiments convinced us our conclusions were correct: New brain cells don’t grow (or are extremely rare) in the adult human hippocampus, a region important for learning and memory. The birth of new neurons in human memory circuits, in other words, declines during childhood to undetectable levels in the adult.
Retraining the Brain’s Vision Center to Take Action
By Robert Sanders – 1 March 2018
Neuroscientists have demonstrated the astounding flexibility of the brain by training neurons that normally process input from the eyes to develop new skills, in this case, to control a computer-generated tone. “We arbitrarily hijacked small groups of neurons in the visual cortex and virtually re-routed their output to make them control a brain-machine interface, or BMI,” said Jose Carmena, senior author of a paper about the development that will appear March 1 in the journal Neuron.
Brain-Machine Interface Study Suggests How Brains Prepare for Action
By Nathan Collins – 16 February 2018
Somewhere right now in Pyeongchang, an Olympic skier is thinking through the twists and spins she’ll make in the aerial competition, a speed skater is visualizing how he’ll sneak past a competitor on the inside line, and a curler is imagining the perfect sweep. It’s called mental rehearsal, and psychologists and athletes alike know that it works: picturing ourselves going through routines, whether it’s figure skating or something more mundane, improves our chances of success.

In 30 years as an oncologist, Dr. Howard Fine estimates he has treated some 20,000 patients with glioblastomas, the most deadly form of brain cancer, “and almost all of them are dead.” Of the 100 new glioblastoma patients he saw last month, “five years from now, only three will be alive,” he said.
Inside the Race to Hack the Human Brain
By John H. Richardson – 16 November 2017
In an ordinary hospital room in Los Angeles, a young woman named Lauren Dickerson waits for her chance to make history.
She’s 25 years old, a teacher’s assistant in a middle school, with warm eyes and computer cables emerging like futuristic dreadlocks from the bandages wrapped around her head. Three days earlier, a neurosurgeon drilled 11 holes through her skull, slid 11 wires the size of spaghetti into her brain, and connected the wires to a bank of computers. Now she’s caged in by bed rails, with plastic tubes snaking up her arm and medical monitors tracking her vital signs.
Four Ethical Priorities for Neurotechnologies and AI
By Rafael Yuste, Sara Goering, et al – 8 November 2017
Consider the following scenario. A paralysed man participates in a clinical trial of a brain–computer interface (BCI). A computer connected to a chip in his brain is trained to interpret the neural activity resulting from his mental rehearsals of an action. The computer generates commands that move a robotic arm. One day, the man feels frustrated with the experimental team. Later, his robotic hand crushes a cup after taking it from one of the research assistants, and hurts the assistant. Apologizing for what he says must have been a malfunction of the device, he wonders whether his frustration with the team played a part.
This scenario is hypothetical. But it illustrates some of the challenges that society might be heading towards.

Gene Editing in the Brain Gets a Major Upgrade
October 19, 2017
Genome editing technologies have revolutionized biomedical science, providing a fast and easy way to modify genes. However, the technique allowing scientists to carryout the most precise edits, doesn’t work in cells that are no longer dividing – which includes most neurons in the brain. This technology had limited use in brain research, until now. Research Fellow Jun Nishiyama, M.D., Ph.D., Research Scientist, Takayasu Mikuni, M.D., Ph.D., and Scientific Director, Ryohei Yasuda, Ph.D. at the Max Planck Florida Institute for Neuroscience have developed a new tool that, for the first time, allows precise genome editing in mature neurons, opening up vast new possibilities in neuroscience research.
Stanford Scientists Seek to Speak the Brain’s Language to Heal its Disease
By Nathan Collins – October 17, 2017
Since the 19th century at least, humans have wondered what could be accomplished by linking our brains – smart and flexible but prone to disease and disarray – directly to technology in all its cold, hard precision … the melding of brains and machines for treating disease and improving human health is now a reality. Brain-machine interfaces that connect computers and the nervous system can now restore rudimentary vision in people who have lost the ability to see, treat the symptoms of Parkinson’s disease and prevent some epileptic seizures. But, the biggest challenge in each of those cases may not be the hardware that science-fiction writers once dwelled on. Instead, it’s trying to understand, on some level at least, what the brain is trying to tell us – and how to speak to it in return.
Facebook Thinks the Most Useful Digital Assistant is the One That Can Read Minds
By W. Harry Fortuna – October 9, 2017
Facebook wants digital assistants like Siri and Cortana to shut up already. People all over are asking Alexa to play them a song, Google Assistant to set a reminder, and surely someone has asked Bixby—Samsung’s new voice assistant—something, but it turns out that no one wants to PDA (personal digital assist) in public. The Facebook solution: give the assistant direct access to our minds.
How We Won Gold in the Cyborg Olympics’ Brain Race
By Serafeim Perdikis, Luca Tonin, and Jose Del R. Millan – August 30, 2017
In October 2016, inside a sold-out arena in Zurich, a man named Numa Poujouly steered his wheelchair up to the central podium. As the Swiss national anthem played, organizers of the world’s first cyborg Olympics hung a gold medal around Poujouly’s neck. The 30-year-old, who became paralyzed after a bicycle accident in his teens, had triumphed in the tournament’s most futuristic event: a video-game-like race in which the competitors controlled their speeding avatars with just their minds.
‘Your Brain on Art’ Conference to Explore the Physiological Side of Creativity

New Kinds of Brain Cells Revealed
August 10, 2017
Under a microscope, it can be hard to tell the difference between any two neurons, the brain cells that store and process information. So scientists have turned to molecular methods to try to identify groups of neurons with different functions. Salk Institute and University of California San Diego scientists have profiled chemical modifications of DNA molecules in individual neurons, giving the most detailed information yet on what makes one brain cell different from its neighbor. This is a critical step in beginning to identify how many types of neurons exist, which has eluded neuroscientists but could lead to a dramatically better understanding about brain development and dysfunction.

Helping or Hacking? Engineers and Ethicists Must Work Together on Brain-Computer Interface Technology
By Eran Klein and Katherine Pratt – June 13, 2017
The potential ability to determine individuals’ preferences and personal information using their own brain signals has spawned a number of difficult but pressing questions: Should we be able to keep our neural signals private? That is, should neural security be a human right? How do we adequately protect and store all the neural data being recorded for research, and soon for leisure? How do consumers know if any protective or anonymization measures are being made with their neural data?

Every human thought starts with a signal traveling from one neuron to another in the brain. Yet we know relatively little about how these connections form. In an effort to watch that process unfold, Australian researchers engineered a nanowire scaffold on a semiconductor chip that enables brain cells to grow and form circuits.
In a Neuro-Techno Future, Human Rights Laws Will Need to be Revisited
By Matt Lam – April 26, 2017
New human rights laws to prepare for advances in neurotechnology that put the ‘freedom of the mind’ at risk have been proposed in the open access journal Life Sciences, Society and Policy. The authors of the study suggest four new human rights laws could emerge in the near future to protect against exploitation and loss of privacy: the right to cognitive liberty, the right to mental privacy, the right to mental integrity and the right to psychological continuity.

New Brain Mapping Technique Reveals Circuitry of Parkinson’s Disease Tremors
by Tom Abate – January 26, 2017
If a piece of electronics isn’t working, troubleshooting the problem often involves probing the flow of electricity through the various components of the circuit to locate any faulty parts. Stanford bioengineer and neuroscientist Jin Hyung Lee, who studies Parkinson’s disease, has adapted that idea to diseases of the brain, creating a new way to turn on specific types of neurons in order to observe how this affects the whole brain.

Brain’s Support Cells Could Explain Mysterious “Spreading Pain”
by Diana Kwon – November 11, 2016
In people who suffer from pain disorders, painful feelings can severely worsen and spread to other regions of the body. Patients who develop chronic pain after surgery, for example, will often feel it coming from the area surrounding the initial injury and even in some parts of the body far from where it originates. New evidence suggests glia, non-neuronal cells in the brain, may be the culprits behind this effect.
Brain Implant Allows Man to Feel Touch on Robotic Hand

New Perspectives on Neuroengineering and Neurotechnologies: NSF-DFG Workshop Report
by C. Moritz, P. Ruther, S. Goering, A. Stett, T. Ball, W. Burgard, E. Chudler, and R. Rao – July 2016
Rapid advances in neuroscience, engineering, and computing are opening the door to radically new approaches to treating neurological and mental disorders and understanding brain function. These new approaches are based on the ability to record and stimulate neural activity with increasing precision. This precision is leading to the rapid expansion of neural interfaces, devices that interact with the nervous system to restore or enable sensory and/or motor function. This report focuses on a subset of neural interfaces termed brain–computer interfaces (BCIs) [also known as brain–machine interfaces (BMIs)].
Brain-to-Brain Interface—the Next Great Leap in Human Communication
By Philip Perry – June 16, 2016
100,000 viewers recently tuned in to see Mark Zuckerberg and Jerry Seinfeld chew the fat on the first ever Q&A session on Facebook Live. At one point, Zuckerberg reiterated that the future of the internet and consequently humanity, lie in technology that gives us telepathic powers. In his view, we would be able to record our own experiences in real time, and share thoughts and feelings directly with friends and loved ones. He called it the “future of communication.” So how close are we to brain-to-brain interfacing?
The Neuroweapons Threat
By James Giordano – May 31, 2016
Nearly two years ago, Juliano Pinto, a 29-year-old paraplegic man, kicked off the World Cup in Brazil with the help of a brain-interface machine that allowed his thoughts to control a robotic exoskeleton. Yet like most powerful scientific breakthroughs, neurotechnologies that allow brains to control machines—or machines to read or control brains—inevitably bring with them the threat of weaponization and misuse, a threat that existing UN conventions designed to limit biological and chemical weapons do not yet cover and which ethical discussions of these new technologies tend to give short shrift.
