Recording device for muscles

This article was written by Carol Clark, senior science communicator at Emory University and editor of eScience Commons

Scientists have made remarkable advances into recording the electrical activity that the nervous system uses to control complex skills, leading to insights into how the nervous system directs an animal’s behavior. 

“We can record the electrical activity of a single neuron, and large groups of neurons, as animals learn and perform skilled behaviors,” says Sam Sober, an associate professor of biology at Emory University who studies the brain and nervous system. “What’s missing,” he adds, “is the technology to precisely record the electrical signals of the muscles that ultimately control that movement.”

The Sober lab is now developing that technology through a collaboration with the lab of Muhannad Bakir, a professor in Georgia Tech’s School of Electrical and Computer Engineering. The researchers recently received a $200,000 Technological Innovations in Neuroscience Award from the McKnight Foundation to create a device that can record electrical action potentials, or “spikes” within muscles of songbirds and rodents. The technology will be used to help understand the neural control of many different skilled behaviors to potentially gain insights into neurological disorders that affect motor control.

“Our device will be the first that lets you record populations of spikes from all of the muscles involved in controlling a complex behavior,” Sober says. “This technique will offer unprecedented access to the neural signals that control muscles, allowing previously impossible investigations into how the brain controls the body.”

“By combining expertise in the life sciences at Emory with the engineering expertise of Georgia Tech, we are able to enter new scientific territory,” Bakir says. “The ultimate goal is to make discoveries that improve the quality of life of people.” 

The Sober lab previously developed a prototype device — electrodes attached to flexible wires — to measure electrical activity in a breathing muscle used by Bengalese finches to sing. The way birds control their song has a lot in common with human speech, both in how it is learned early in life and how it is produced in adulthood. The neural pathways for birdsong are also well known, and restricted to that one activity, making birds a good model system for studying nervous system function.

“In experiments using our prototype, we discovered that, just like in brain cells, precise spike timing patterns in muscle cells are critical for controlling behavior — in this case breathing,” Sober says.

The prototype device, however, is basic. Its 16 electrodes can only record activity from a single muscle — not the entire ensemble of muscles involved in birdsong. In order to gain a fuller picture of how neural signals control movement, neuroscientists need a much more sophisticated device.

The McKnight funding allowed Sober to team up with Bakir. Their goal is to create a micro-scale electromyography (EMG) sensor array, containing more than 1,000 electrodes, to record single-cellular data across many muscles. 

The engineering challenges are formidable. The arrays need to be flexible enough to fit the shape of small muscles used in fine motor skills, and to change shape as the muscles contract. The entire device must also be tiny enough not to impede the movement of a small animal.

“Our first step is to build a flexible substrate on the micro-scale that can support high-density electrodes,” Bakir says. “And we will need to use microchips that work in parallel with 1,000 electrodes, and then attach them to that substrate.”

To meet that challenge, the Bakir lab will create a 3D integrated circuit. “Essentially, it’s building a miniature skyscraper of electrical circuits stacked vertically atop one another,” Bakir says. This vertical design will allow the researchers to minimize the size of the flexible substrate.

“To our knowledge, no one has done what we are trying to do in this project,” Bakir says. “That makes it more difficult, but also exciting because we are entering new space.”  

The Sober lab will use the new device to expand its songbird vocalization studies. And it will explore how the nervous system controls the muscles involved when a mouse performs skilled movements with its forelimbs. 

An early version of the technology will also be shared with collaborators of the Sober lab at three different universities. These collaborators will further test the arrays, while also gathering data across more species.

“We know so little about how the brain organizes skilled behaviors,” Sober says. “Once we perfect this technology, we will make it available to researchers in this field around the world, to advance knowledge as rapidly as possible.”

The mission of the McKnight Foundation’s Technological Innovations in Neuroscience Award, as described on its website, is “to bring science closer to the day when diseases of the brain and behavior can be accurately diagnosed, prevented and treated.”

Sam Coogan

Sam Coogan has been chosen for an Air Force Office of Scientific Research Young Investigator Award for his research project entitled "Scalable Analysis and Control of Dynamic Flow Networks.” Coogan is an assistant professor in the Georgia Tech School of Electrical and Computer Engineering (ECE).

Coogan’s project will develop fundamental theory for controlling and designing networks that model the flow of physical material among interconnected components. These systems are called physical flow networks and are used to model, for example, vehicular transportation networks, air traffic networks, and civil infrastructure. The fundamental commonalities of such flow networks suggest a unified approach for modeling, while domain-specific features point towards a full understanding of their rich behavior. 

In physical flow networks, nonlinearities in each component compound due to the network interactions. For example, congestion in one link of a road network can impact traffic flow in other parts of the network over time. In applications, such networks are becoming larger, more complex, and increasingly distributed, and there is an urgent need to study the mathematical models that underlie many of these systems. The proposed research will focus on using and extending tools from nonlinear system analysis to study and control these physical flow networks.

Coogan holds a joint faculty appointment with Georgia Tech’s School of Civil and Environmental Engineering. Prior to joining Georgia Tech in 2017, he was an assistant professor in the Electrical Engineering Department at the University of California, Los Angeles from 2015-2017. 

In January 2018, Coogan received an NSF CAREER Award to study the control of traffic networks with an emphasis on autonomy, and in December 2017, he received the IEEE Transactions on Control of Network Systems Best Paper Award at the 56th IEEE Conference on Decision and Control.

Alan Doolittle

Alan Doolittle has been appointed as the Joseph M. Pettit Professor in the Georgia Tech School of Electrical and Computer Engineering (ECE), effective on September 1, 2019.

Doolittle is a proud, two-time Georgia Tech alumnus, earning his B.E.E. degree with highest honors in 1989 and his Ph.D. in Electrical Engineering in 1996. After graduating with his doctorate, he worked as a research engineer in ECE for five years and then joined the School's academic faculty in 2001. Doolittle leads the Advanced Semiconductor Technology Facility, which has an estimated equipment capitalization of $6 million. 

Doolittle advises eight Ph.D. students who work in the areas of microelectronic fabrication, materials growth, characterization, neuromorphic computational devices, power, high frequency transistors, and optoelectronic devices. To date, he has graduated 23 Ph.D. students, 12 master’s students, and 45 undergraduate students.      

Doolittle pioneered the area of hyper doping of wide bandgap semiconductors, which has enabled the creation of new devices that use quantum mechanical processes to reduce power losses and to allow new ways of interconnecting advanced power and optoelectronic devices. He also pioneered the synthesis of lithium-metal-oxides, which have recently gained traction for very low power neuromorphic devices; these devices emulate human brain functionality.

From 2003-2009, Doolittle was the first assistant professor at Tech to win a Multidisciplinary University Research Initiatives (MURI) award, and in fact, he was the lead PI on two MURI programs during this period. These initiatives focused on the development of next generation epitaxial systems for three-dimensional epitaxy. Doolittle and his team developed and exploited epitaxial multifunctional oxides, a newly developing family of materials that seek to interconnect at the atomic scale using more than one environmental force in order to facilitate the development of new sensors and actuators. One example of materials that were birthed out of this field are “multiferroics,” where electric fields can tune magnetic moments. The latter MURI was an extension of his NSF CAREER Award from 2004 and led to a new branch of science in multifunctional materials.    

Doolittle currently leads a third MURI program aimed at building nanoscale devices that operate in a way that is similar to various brain functions. His MURI team’s goal is to develop an artificial retina that can learn autonomously and be used for advanced image recognition cameras for national defense and police work. He is a co-PI on a fourth MURI, led by Samuel Graham, the Eugene C. Gwaltney Chair and Professor of the George W. Woodruff School of Mechanical Engineering. This program examines the nanoscale engineering of thermal interfaces, so as to improve heat dissipation in power electronics.

Over the years, Doolittle and his colleagues have raised approximately $38 million in research funding from multiple government agencies and industry. He has published 157 refereed journal and conference papers, and he has been issued nine patents. For his hard work and dedication to research, Doolittle was recognized with the Georgia Tech Outstanding Achievement in Research Program Development Award in 2008, the 2002-2003 Student Government Faculty of the Year Award, and the 2005 ECE Outstanding Junior Faculty Member Award.

An excellent classroom teacher, Doolittle earns teaching ratings from undergraduate and graduate students that consistently exceed the School’s norms. He has taught 1,009 undergraduates and 178 graduate students with teaching effectiveness ratings of 4.7 out of 5 in courses such as Microelectronics Circuits, Semiconductor Devices, Renewable Energy Devices, and Introduction to Microelectronic Technology. 

Doolittle is a two-time recipient of the Richard M. Bass/Eta Kappa Nu Outstanding Teacher Award, an honor determined by a majority vote of the ECE senior class, in 2003 and 2011. He also received the 2006 Georgia Tech W. Howard Ector Outstanding Teacher Award and the 2005 Lockheed Martin Aeronautics Company’s Dean’s Award for Teaching Excellence. Over the years, he has made his lab available for campus and ECE outreach tours and has advised high school teachers through various programs.           

Doolittle has long been internationally recognized as a leader in his field. He has chaired the two biggest conferences in his area of expertise, the International Workshop on Nitride Semiconductors and the International Conference on Nitride Semiconductors, and he has also been chair and program chair for these and other semiconductor conferences several times.

Georgia Tech Arts is excited to announce that it has received a grant of $150,000 from the Charles Loridans Foundation to bring professional contemporary dance companies, from around the globe and Atlanta, to the campus of Georgia Tech. These selected groups will further the mission of Georgia Tech Arts by integrating performing arts into the lives and work of students, faculty, and the surrounding community. Presenting a blend of nationally recognized and locally based dance companies will ultimately raise the profile of contemporary dance across Atlanta and Georgia Tech.

Georgia Tech Arts newly vested director, Dr. Aaron Shackelford, explains the focus on contemporary dance programming in future seasons: “The cultivation of contemporary dance at Georgia Tech can make a uniquely strong contribution to the field in terms of both audience and artistic development. Contemporary dance companies and choreographers are also on the forefront of pressing issues that face the lives of students and many members of the community. These include the deep collaboration inherent to their creative process, the exploration of social issues, reconsideration of physicality, and abstract thinking. Given that these topics are not easily taught or established in the classroom, Georgia Tech Arts, along with the selected dance companies, is committed to providing meaningful engagement experiences for students and beyond.”

The two-year grant supported the sold-out performance of VIVA MOMIX on March 1, 2020, a work that Georgia Tech Arts Dr. Shackelford added to the 2019-2020 season programming after his arrival to the department this past summer. It represents Georgia Tech Arts’ commitment to establishing itself as a hub for innovative dance work that invites the entire community to share in these encounters.

With the funding of the Loridans Foundation, Georgia Tech Arts will also present three additional, yet to be announced contemporary dance ensembles in fall 2020, spring 2021, and fall 2021.

“The Trustees of the Charles Loridans Foundation are so pleased that Dr. Aaron Shackelford and his team at Georgia Tech Arts want to bring the best national and local contemporary dance companies to the Ferst Center,” says Bob Edge, Chair of the Charles Loridans Foundation. “This dance initiative can be artistically important not only to the Tech community but all of Metropolitan Atlanta.  Recent enhancements at the Ferst make it an ideal venue for the ambitious dance presentations Dr. Shackelford has in mind; and the Loridans Trustees are very pleased to support this important program with a multi-year grant.”

Georgia Tech Arts will announce its full 2020-2021 season on May 6, 2020.
