IEEE Life Sciences Newsletter

Welcome to the June 2014 IEEE Life Sciences eNewsletter

This issue of the IEEE Life Sciences Newsletter brings you some very interesting and leading-edge information on the intersection between fundamental neuroscience research and electronic engineering. The May issue of the Proceedings of the IEEE was a special issue entitled "Engineering Intelligence Electronic Systems Based on Computational Neuroscience". In an overview article, Dr. Mark McDonnell, who co-edited that issue, summarizes the context and contributions of the Special Issue. We also present three papers that summarize contributions to the Special Issue with particular relevance to life sciences in respect of neuroscience. We especially wish to thank Dr. McDonnell, a Senior Member of IEEE, for arranging for these articles.

Special Issue of Proceedings of the IEEE highlights the contributions of Electronic Engineering to Computational Neuroscience

By Mark D McDonnell

In May 2014, Proceedings of the IEEE published a Special Issue focused on elucidating the rapidly growing intersection between electronic engineering and the scientific field of computational neuroscience [1]. This field is an interdisciplinary area of scientific research in which one of the primary goals is to understand how electronic activity in brain cells and networks enables biological intelligence.

The power of small brains

By Nicolas Franceschini

For several decades, engineers and biologists have attempted to harness animals' sensory-motor intelligence to build autonomous machines. In the May 2014 issue of Proceeding of the IEEE, devoted to Engineering Intelligent Electronic Systems Based on Computational Neuroscience, the author describes how microoptical, behavioral and electrophysiological experiments carried out on insects have led to building seven proof-of-concept robots equipped with insect-derived neuromorphic sensors and autopilots. These constructions in turn are used to better apprehend the clever tricks used by insects, which negotiate their complex environments with a level of agility that greatly outpasses that of both vertebrate animals and present-day aerospace robots.

Neuromorphic Engineering: Neuromimetic Computation for Understanding the Brain

By Mostafa Rahimi Azghadi, Giacomo Indiveri, and Derek Abbott

Neuromorphic engineering attempts to understand the computational properties of neural processing systems by building electronic circuits and systems that emulate the principles of computation in the neural systems. The electronic systems that are developed in this process can serve both engineering and life sciences in various ways ranging from low-power brain-like computing embedded systems to neural-based control, brain machine interfaces, and neuroprosthesis. To realize such systems, various approaches and strategies with their own advantages and limitations, may be adopted. Here, we provide a summary of our recent article published in the proceedings of the IEEE [1], where we have discussed and reviewed the various approaches to the design and implementation of neuromorphic learning systems, and pointed out challenges and opportunities in these systems.

Large-scale modeling of the behaving brain

By Terrence C. Stewart and Chris Eliasmith

We review the methods used to construct Spaun, the first biologically detailed brain model capable of performing cognitive tasks. Spaun has 2.5 million simple, spiking neurons with 60 billion connections between them. These neurons are arranged to respect known anatomical and physiological constraints of the mammalian brain. The resulting model can perform eight different perceptual, motor, and cognitive tasks (see http://nengo.ca/build-a-brain/spaunvideos for video demonstrations). We built Spaun using Nengo, our general-purpose tool set for building systems that compute using neuron-like components in a biologically constrained manner. Building such systems is critical for improving our understanding of how the brain works, and to make use of recent advances in neuromorphic hardware.
