Wired In: Aron K. Barbey

Each week, staff writer Paul Wood profiles a high-tech difference-maker. This week, meet ARON K. BARBEY, the University of Illinois professor of psychology, neuroscience and bioengineering who is director of the Center for Brain Plasticity, the Decision Neuroscience Laboratory and the Intelligence, Learning and Plasticity Initiative. As his titles suggest, he has a major interest in brain plasticity — the brain's ability to change throughout life by forming new connections between brain cells in learning and other ways.

Since arriving at Illinois almost seven years ago, you've contributed to the study of human intelligence — to understand the biological foundations of human intelligence and to develop tools and methods that can improve human judgement and decision-making. Tell us about that.

A powerful insight for understanding human intelligence derives from the brain's most unique and essential characteristic: plasticity. The brain demonstrates a remarkable capacity to reconfigure itself — to continually update prior knowledge on the basis of new information and to actively generate internal predictions that guide adaptive behavior and decision making.

Why is plasticity important?

Contemporary research and theory conceive of the brain as a dynamic and active inference generator that anticipates incoming sensory inputs, forming hypotheses about the world that can be tested against sensory signals that arrive in the brain. Plasticity is therefore critical for the emergence of human intelligence, providing a powerful mechanism for updating prior beliefs, generating dynamic predictions about the world and adapting in response to ongoing changes in the environment.

Does it have a role in healing?

Recent clinical evidence further indicates that plasticity is a hallmark of the brain's response to traumatic injury and neurological disease, promoting the formation of new neurons, connections and blood-supply pathways that enable the brain to adaptively reorganize neural circuits and providing a remarkable opportunity for functional recovery.

How are you contributing to this field?

Our research group at the Beckman Institute provides a catalyst for basic and translational research that aims to measure, model and elicit brain plasticity. It promotes multidisciplinary studies of the neurobiological foundations of brain plasticity and innovative approaches and technologies to drive neural plasticity through the application of adaptive cognitive training, non-invasive brain stimulation, physical-fitness training, mindfulness meditation and nutritional intervention. We conduct clinical trials in healthy and clinical populations that investigate science and technology that aims to enhance performance and mitigate the effects of cognitive aging and traumatic brain injury.

What impact are you having?

Our aim is to conduct research that has broad, transformative impact — guiding public-policy recommendations about the nature of human intelligence in education, business, artificial intelligence, and medicine.

How has your field changed since your career began?

We have increasingly realized that human intelligence reflects individual differences in the system-wide topology and dynamics of the human brain. Rather than originating from a specific brain region or network, accumulating evidence suggests that brain network dynamics are critical for the diverse range of mental abilities underlying general intelligence.

What's your proudest or most significant achievement?

We have developed a new approach to understanding the nature and mechanisms of human intelligence, the Network Neuroscience Theory. According to this framework, general intelligence emerges from the small-world topology of brain networks and the dynamic reorganization of its community structure in the service of system-wide flexibility and adaptation.

TECH TIDBITS ... from ARON BARBEY

Do you have interests in social media? Any startups? We currently do not have a startup company but are interested in exploring the possibilities.

What's your favorite app? AFNI (Analysis of Functional NeuroImages).

On Facebook, I follow ... I am afraid I do not actively use Facebook. However, our lab has a twitter account (@DecisionNeurosc).

What are you reading right now? I typically read science fiction and am reading the Frank Herbert "Dune" novels.

Do you have any wearable electronics? No. I have a fully mechanical (not battery-powered) watch and a cellphone. However, the community at Illinois is developing wearable technologies and a suite of apps to assess a variety of health metrics in real-time, and this technology is quickly advancing (e.g., to measure physiological response, blood pressure, etc.)

Do you have an entrepreneurial hero? Arnold O. Beckman.
