About
Karthikeyan Balasubramanian is a leading researcher in neural engineering, specializing in brain-machine interfaces (BMIs) and motor cortical plasticity. His work focuses on how the brain adapts to control external devices, particularly in the context of chronic amputation. In his most-cited study (2017, 23 citations), he demonstrated that long-term BMI exposure in amputated primates induces significant changes in ensemble-level functional connectivity within the primary motor cortex (M1), revealing neural plasticity beyond single-neuron activity. His earlier work (2013, 16 citations) showed that operant conditioning with biofeedback can effectively train multiple degree-of-freedom BMI control in amputee models, offering a pathway for prosthetic control when natural motor mappings are lost. Balasubramanian also explored the emergence of coordinated reach-to-grasp movements via BMI (2018, 12 citations), providing insights into motor cortex development. Additionally, he developed a fast, efficient method for tracking chronically recorded single-units across days (2013, 3 citations), addressing a key challenge in long-term BMI studies. His research bridges fundamental neuroscience and translational neuroprosthetics, with implications for restoring movement in individuals with limb loss.
