BIO(BRAIN)-X International Summer School


October 2019

The 18th International Summer School on BIO(BRAIN)-X: Biocomplexity, Biodesign, Bioinnovation, Biomanufacturing and Bioentrepreneurship, sponsored by the NSF, the University of Houston Biomedical Engineering Department and technically co-sponsored by the IEEE Brain Initiative and the IEEE Engineering in Medicine and Biology Society, was held at the Chania Academy, Crete, June 9-15, 2019. This summer school was a continuation of previous summer schools. Twenty-five students and eight distinguished faculty attended the 18th summer school. The NSF, the IEEE Brain Initiative and the University of Houston co-sponsored 25 students.

Transcranial Focal Stimulation Using Concentric Ring Electrodes

• Statement of the challenge/opportunity: gaps, opportunities, and drivers

About 12 in 100 people worldwide, or 800 million, are suffering from neurological disorders such as epilepsy (having multiple recurrent seizures which are uncontrollable electrical activity of the brain), chronic pain, Parkinson’s Disease, etc. [1]. Around 450 million people worldwide are affected by psychiatric disorders [1]. Despite decades of research, new drugs, and advances in surgical therapy, 30% or more of the patients with epilepsy or psychiatric disorders do not respond to medical treatment or suffer from its severe side effects [2]. Epilepsy surgery and devices can control seizures in some patients with drug-resistant epilepsy but require advanced and often invasive diagnostic neurophysiology techniques. New solutions are needed for alternatives to drugs and to more invasive and expensive surgeries.

Regulation of arousal via online neurofeedback improves human performance in a demanding sensory motor task

High arousal can adversely affect task performance. Walking over a balance beam that sits 10 cm over the floor, for example, will be easier for most people than walking over a beam that is fixed at a height of 10 m, where a misstep could lead to grave injury. Another example is referred to as “pilot induced oscillations” (PIOs), where airplane pilots – under high arousal – dangerously overcompensate for small control errors in a way that can quickly escalate to losing control over and/or crashing the plane. In 1908, Yerkes & Dodson first formally described an inverse U-shape relationship between arousal and performance under high task difficulty [1]( see Figure 1.A). From the perspective of neurophysiology, there is evidence in support of the hypothesis that an interplay between the anterior cingulate cortex (ACC) and locus coeruleus (LC) – regions implicated in monitoring task performance and mediating stress responses – may play a critical role in explaining this phenomenon [2,3](see Figure 1.B). In a previous study, our group identified EEG signatures of PIO propensity or task-dependent arousal in a virtual flight task, a so called “boundary avoidance task” (BAT), where difficulty progressively increases over 90 seconds to induce PIOs and task failure, i.e. crashing the plane into a boundary [4](see Figure 1.C).

Notes from the Cybathlon BCI series 2019

Ricardo Chavarriaga

Development of brain-computer interface technologies is a long term endeavour that faces multiple challenges. The transition from the controlled conditions of research laboratories to real-life is paved with uncertainties about multiple factors that affect human and machine performance. The Cybathlon tries to address these difficulties by setting up an event in which people with disabilities can compete on several disciplines where they perform day-to-day activities using state-of-the-art assistive technologies [1].

The Possibilities to Augment Physical Capabilities using Brain Machine Interfaces


October 2019

Christian I. Penaloza and Shuichi Nishio

Augmenting Human Capabilities

As humans, we have always tried to augment our physical and cognitive capabilities to enhance the strength or endurance of our bodies or minds. Although the concept of human augmentation is not new, with the fast development of new robotic systems, AI and genetic engineering, it has accelerated in the last decade and will continue accelerating even further in the upcoming decades. The expected outcome will be a new kind of human beings, superhumans or cyborgs, that will seamlessly integrate machines with their human bodies and will have unprecedented capabilities to achieve things that today’s humans are not capable of.
