Key takeaways

  • Miguel Nicolelis belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Miguel Nicolelis to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Miguel Nicolelis from memory before moving on to harder problems.

Reference excerpt

Miguel Ângelo Laporta Nicolelis (Portuguese pronunciation: [miˈɡɛw ˈɐ̃ʒelu lɐˈpɔɾtɐ nikoˈlɛlis], born March 7, 1961), is a Brazilian scientist, physician and Duke School of Medicine Professor in Neuroscience at Duke University, best known for his pioneering work surrounding brain-computer interface (also known as "brain-machine interface") technology.

Biography Nicolelis holds a medical degree from the University of São Paulo (1984), a doctorate in Sciences (General Physiology) from the University of São Paulo (1989) and a PhD in Physiology and Biophysics from Hahnemann University (now Drexel University College of Medicine). He is a full professor in the Department of Neurobiology and co-director of the Neuroengineering Center at Duke University (USA). Founder of the Alberto Santos Dumont Association for Research Support (AASDAP) and the Santos Dumont Institute (ISD), he proposed the use of science as an agent of social and economic transformation. Nicolelis is a Researcher at the International Institute of Neurosciences Edmond and Lily Safra (IIN-ELS) and Coordinator of the Andar de Novo Project, developed at AASDAP in São Paulo. He and his colleagues at Duke University implanted electrode arrays into a monkey's brain that were able to detect the monkey's motor intent and thus able to control reaching and grasping movements performed by a robotic arm. This was possible by decoding signals of hundreds of neurons recorded in volitional areas of the cerebral cortex while the monkey played with a hand-held joystick to move a shape in a video game. These signals were sent to the robot arm, which then mimicked the monkey's movements and thus controlled the game. After a while the monkey realised that thinking about moving the shape was enough and it no longer needed to move the joystick. So it let go of the joystick and controlled the game purely through thought. A system in which brain signals directly control an artificial actuator is commonly referred to as brain-computer interface ("BCI"). On January 15, 2008, Nicolelis lab saw a monkey implanted with a new BCI successfully control a robot walking on a treadmill in Kyoto, Japan. The monkey could see the robot, named CB, on a screen in front of him, and was rewarded for walking in sync with the robot (which was under the control of the monkey). After an hour the monkey's treadmill was turned off, but he was able to continue to direct the robot to walk normally for another few minutes, indicating that a part of the brain not sufficient to induce a motor response in the monkey had become dedicated to controlling the robot, as if it were an extension of itself. In 2011 Miguel Nicolelis's team at Duke placed electrodes in the brains of 11 patients with Parkinson's disease while they were undergoing separate brain surgery. The team could predict hand movements from the brain signals. Nicolelis is a co-founder and scientific director of the Edmond and Lily Safra International Institute for Neuroscience of Natal, a brain research facility in Brazil in 2006 and the Santos Dumont Institute built and qualified as a Social Organization in 2014. On August 3, 2010, Nicolelis was awarded an NIH Director's Pioneer Award to continue his research on brain-machine interface technology. On January 5, 2011, Dr. Nicolelis was appointed by Pope Benedict XVI as an ordinary member of the Pontifical Academy of Sciences. He was interviewed by Charlie Rose in 2003. Nicolelis is a fan of Sociedade Esportiva Palmeiras, a Brazilian football club; a football ball with Palmeiras crest can be seen at his website. He is currently working on a project that allowed paraplegic Juliano Pinto, a 29-year-old with complete paralysis of the lower trunk to deliver the kickoff at the opening game of the 2014 FIFA World Cup, in Brazil.

Brain to brain

In 2013, a report of research by Nicolelis and others was published which showed brain to brain communication between two rats using brain–computer interfaces. This result may demonstrate the feasibility of a biological computer consisting of a network of animal, or human, brains. Currently, researchers are divided on their views of this research. Critics state that there are flaws in the scientific methods used and that there is lack of controls. They claim that some of the scientific claims are rendered "far-fetched at best." One researcher stated the work was similar to a "poor Hollywood science fiction script." Proponents have praised this research for drawing attention to Brain to Brain Interfaces as a way of studying neural systems: "The study helps to promote the role of BMIs not only in prosthetic applications, but also as scientific tools. It's a contribution to that." Ron Frostig, a neuroscientist at the University of California, Irvine, has described this brain to brain work as "an amazing paper" and a "beautiful proof of principle" that information can be transferred from one brain to another in real time.

Critiques of Neuralink Nicolelis's evaluation of Elon Musk's Neuralink, is that most of what Neuralink claims as "novelty" had already been performed by his lab in the early 2000s; that there are ethical concerns about how the company markets and uses this technology; and that most patients do not want to undergo surgery to recover their movements. Other researchers have raised questions about Neuralink's transparency in scientific research processes, patient safety considerations, and the potential implications for neurotechnology.

Worked examples

Example 1 — a first encounter with Miguel Nicolelis

Start with the simplest possible case. Write down what Miguel Nicolelis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Miguel Nicolelis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Miguel Nicolelis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Miguel Nicolelis

In research
Miguel Nicolelis appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Miguel Nicolelis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Miguel Nicolelis is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, American people of Brazilian descent, Brain–computer interface, so understanding it makes those chapters shorter.
In everyday life
Look for Miguel Nicolelis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
