Meeting of the Global Current and Emerging Brain Initiatives at the IEEE SMC BMI Workshop

Michael H. Smith

On October 9, 2018, the SMC Brain-Machine Interface Systems (BMI) Workshop also featured a first-of-its-kind meeting of Global Current and Emerging Brain Initiatives. This meeting was hosted by the IEEE President, James Jefferies, and Chaired by Michael H. Smith. The meeting brought together global Brain Initiative leaders and representatives from other groups working on large-scale multi-year brain projects from Australia, Canada, China, Europe, Japan, Korea, New Zealand, Poland, Russia, and the US as well as representatives from the IEEE Brain Initiative, the International Neuroethics Society, industry, and other stakeholders.

Reminiscence of Seventh International BCI Meeting

Koji Koizumi

This was the first time I attended the International BCI meeting. This event took place on May 21 – 25, 2018 at the Asilomar Conference Center in Pacific Grove, California, USA. To tell the truth, this was the first conference I have attended. Just about the time I finished writing my graduation thesis at the University of Tokyo, I got to know about this meeting through the call for papers via its website. Because I was just beginning in BCI, I wanted to deepen my understanding of the field and benefit from the experience and advice of other researchers. Therefore, I immediately decided to submit an abstract. Fortunately, I received the Student Award at this meeting and received a travel grant from the IEEE Brain Initiative. I would like to take this opportunity to express my appreciation to IEEE Brain Initiative. In conclusion, this conference was truly amazing and I was really pleased having participated in this conference.

Discovery of New Neurological Networks

Dr. Salvatore Domenic Morgera

The human nervous system provides energy efficient, highly complex realization and control of how we sense, think and act. For machines designed by humans, the ideas of energy efficiency and complexity are at odds, thus the question of how the central nervous system (CNS) really works has received intense scrutiny for decades. Researchers at the University of South Florida (USF) under the direction of Dr. Sal Morgera have discovered a sophisticated electric near-field generated in an energy efficient, natural manner by our billions of myelinated nerve fibers. This electric near-field is roughly the counterpart of the magnetic near-field used in smartphone contactless payment services such as Apple Pay® and Google Wallet®, known as Near Field Communications, or NFC.

Capturing Touch for Prosthetic Limbs Through Artificial Skin

Luke E. Osborn and Nitish V. Thakor

Those living with upper limb differences face numerous challenges, including lost limb movement and dexterity as well as missing sensory information during object manipulation. From a user’s perspective, upper limb prostheses still have several issues with control, general discomfort from the socket, and lack of sensory feedback 1. Significant efforts have resulted in sophisticated algorithms for decoding intended prosthesis movements along multiple degrees of freedom that have enabled amputees to regain more dexterous prosthesis control 2. Another seminal advancement is targeted muscle reinnervation surgery 3, which targets nerves to different intact muscle groups such as on the chest to provide a source of well differentiated myoelectric signals for prosthesis control.

The Cybathlon BCI race highlights mutual learning as the roadmap to translational non-invasive motor imagery BCI

Serafeim Perdikis, Luca Tonin, Sareh Saeedi, Christoph Schneider, José del R. Millán

The Cybathlon competition has been the first ever international championship for disabled individuals competing with assistive devices1. Held in Zürich, Switzerland in October 2016, it featured the Brain-Computer Interface (BCI) race as one of its most innovative disciplines2. The Cybathlon BCI race aspired to accelerate the development of BCI technology, promote end-user and public awareness, as well as to attract funding agencies and entrepreneurs. The discipline consisted of a virtual race game called “Brain Runners” (Figure 1), where four brain-controlled avatars could be pushed towards the finish line by means of (up to) three mental commands. These commands should be issued by the “pilot” exclusively on suitable color-coded areas (spin on cyan, jump on magenta and slide on yellow “pads”). Pilots should also be able to “idle” and avoid any command delivery on additional white pads. Erroneous commands would slow down the pilot’s course down the race track, which consisted of sixteen consecutive pads (four of each type) placed in random order. Brain Runners has been designed to assess all those skills that are considered crucial to allow BCI in real-world scenarios, while also being attractive to Cybathlon’s live audience. Eleven teams representing BCI research groups from around the world have participated in the competition.

Cortico-Striatal Circuits are a Key Component of Learning in brain-machine interface tasks

Ryan Neely, Aaron Koralek, Vivek Athalye, Rui Costa, Jose Carmena

Establishing a functional link between the human nervous system and computer systems could enable a broad range of applications, from medical treatments to consumer-focused products. Brain-machine interface (BMI) technologies have shown early promise in restoring communication and movement capabilities to paralyzed individuals, and there remains a strong research as well as commercial interest in developing these technologies further. Many BMI systems work by measuring neural signals, and “decoding” these signals to produce activity in an artificial effector- for example, a computer cursor or robotic appendage…

Wearable Microwave Imager and BMI Development

Joel Libove, David Schriebman and Mike Ingle

Ultrawideband microwave pulses having widths of 20-50 picoseconds can penetrate the skull and travel into deep brain tissues. Recently developed radar integrated circuits can generate customizable pulses, launch them into the cortex, and monitor the resulting reflections from brain tissue boundaries. The amplitude of these reflections varies slightly, in real time, due to metabolic changes in brain tissue undergoing localized activity, enabling functional activity to be spatially mapped. The arrival time of these reflections also varies with the pulsation of arterial walls, additionally facilitating real-time imaging of neurovascular structures. A helmet under development, with 128 dual-channel radar ICs shows promise for enabling a wearable brain machine interface.

The Potential of Neuroimaging-Guided Sensorimotor Rehabilitation

James Sulzer, Roger Gassert

Stroke, caused by a cerebrovascular lesion, is one of the most debilitating diseases in the world. While physical and occupational therapy play an important role in the rehabilitation process, we are still unable to determine effective treatment strategies for the reduction of stroke-related impairments. It appears that reducing impairments after stroke may be mostly spontaneous and that therapy primarily supports compensation. Despite the source of the injury in the brain, treatment strategies are only at the limb level. The focus on the limbs while brain reorganization goes unmonitored could controversially result in compensatory neuroplasticity that limits recovery.

Exploiting DNA Sequencing Technology for High-Throughput Neuroanatomy

Justus M Kebschull

The brain is the most complex organ of the body, formed by billions of neurons and trillions of synapses, all precisely connected by 100,000 miles of wiring. Understanding how the brain processes information relies, at least in part, on understanding these connections. However, in mammals, we still lack a fine-resolution map of neural connectivity.
