In some conditions, such as injury or disease plasticity can be maladaptive, leading to motor impairments. This can present as involuntary movement or the inability to move.
My fundamental work studying plasticity in spinal circuits in healthy states will inform investigations directed toward understanding mechanisms of disease.
