Researchers at the University of Texas at Austin have developed a method using transcutaneous electrical spinal stimulation to significantly reduce the learning time required for brain-computer interface (BCI) proficiency. This approach enhances brain signal clarity by pre-activating neural circuits related to movement, allowing faster and more precise device control. The technology holds potential for improving BCI usability in individuals with motor impairments, blending spinal and cortical stimulation for neurorehabilitation.
