About Sergiy Yakovenko
The focus of our interdisciplinary research is to study the coordinated action of neural, muscular, and skeletal systems controlling goal-directed and stereotypic movements.
The neuro-musculo-skeletal (NMS) system evolved to control mechanical actions, e.g. walking, running, balancing and reaching. Since these and other common behaviors are produced by the integrated action of multiple components of the NMS system, investigating the details of this emergent organization of movement control is a major challenge. Our laboratory addresses this challenge with an interdisciplinary approach that combines multi-electrode recording and stimulation techniques with advanced computational tools in the field of neuromechanics and innovative methodology.
Besides the general question of understanding how the brain works we are working on the following specific topics:
-- What is the pattern of interactions between multiple neuromechanical mechanisms involved in the control of movement?
-- What are the evolutionary constraints of neuromechanical organization?
-- What mechanisms are responsible for the way we acquire new motor skills?
-- How can we use the hierarchy and redundancy of control pathways to overcome movement deficits due to stroke and spinal cord injury?

I have established my laboratory engaged in independent neurophysiological research in motor cortex and spinal cord using new types of electrodes placed in neural structures and using new computational methods for the analysis of large neural and behavioral datasets. My team has multidisciplinary expertise from chronic long-term recording capabilities in animals with brain trauma to computational analytical skills to describe the organization principles of movement control. With our current methods we can observe diverse neural processes over large cortical areas in the nervous system, and the analysis of this activity requires the development of parallel theoretical framework to overcome the limitations of standard reductionist methods. My strategy for the ‘reverse engineering’ of neural controller is to integrate the simplest computational models to aid in the interpretation of experimental data collected to test these same models and allow us to see the ‘big picture’. I am convinced that this framework will yield the highest degree of insight into the complex interactions within the neuro-musculo-skeletal system.
My current research direction is focused on the principles of interactions between the mechanisms of neuromechanical hierarchy both the context of stroke and spinal cord injury using animal models and in the context of improving control of advanced arm prosthesis for human amputees. One of the challenges for the current brain-machine interface is the lack of functional understanding of how neural processes interact within and across the different levels of neuraxis. Specifically, we have limited understanding of how cortical synergies or motor primitives are controlled to produce coupled sequential activation observed in reaching movements and locomotion. Lissencephalic (smooth) rat cortex is the perfect target for the microelectrode arrays with recording-stimulation capabilities to address this question. Building on my experience in recording and stimulation of cat motor cortex and brainstem structures I have collected preliminary data in rats using floating microelectrode arrays to demonstrate the feasibility of the methods. We have developed a new type of walkway specifically designed to create a dextrous locomotor task that requires cortical contribution in rodents. In addition, we are developing neuromechanical models for data processing that will guide our analysis.
My research experience and expertise in conducting multidisciplinary studies are advantageous prerequisites to the success of proposed experimental and theoretical studies and the development of innovative technologies for rehabilitation. Results of these studies may lead to the development of novel therapies using closed-loop stimulation systems to quantify and to restore impaired motor functions.
