Metaplasticity & Bioinformatics
Adam R Ferguson PhD
Understand and harness CNS plasticity to promote recovery of function after brain and spinal injury through bench-science and translational computational approaches.
Our research focuses on mechanisms of recovery after neurological trauma. Injuries to the brain and spinal cord invoke numerous, interacting biological changes that work in concert to determine recovery success. Some of these biological changes have contradictory effects at different phases of recovery. For example, mechanisms of synaptic regulation can contribute to cell death in the early phases of recovery but may promote plasticity and restoration of function at later stages. Understanding the mechanisms of neurological recovery in the complex microenvironment of the injured central nervous system (CNS) requires large-scale integration of biological information and functional outcomes (i.e., Bioinformatics). Our work uses a combination of laboratory studies and statistical modeling approaches to provide an information-rich picture of the syndrome produced by trauma in translational in vivo models. The long term goal of this research is to provide system-level therapeutic targets for enhancing recovery of function after brain and spinal injury.
AREAS OF FOCUS
Computational Syndromic Discovery: Development of an aggregate database of basic spinal cord injury research data from multiple research centers to enable sophisticated knowledge-discovery, data-sharing, and multivariate quantification of the complete constellation of changes produced by spinal cord injury.
Bench science: Modulation of glutamate receptor metaplasticity and its role in spinal cord learning and recovery of function after spinal cord injury. Techniques: biochemistry (quantitative western, qRT-PCR, ELISA), histology (immunohistochemistry, in situ hybridization), quantitative image analysis (robotic microscopy, confocal, deconvolution, image math) and behavioral analysis (locomotor scaling, fine-motor control, learning and memory).
