This paper introduces a flexible thin-film transistor platform for active neural sensing, demonstrating long-term stability and high channel count scalability in vivo.

This study introduces Adaptive Charge Modulation (ACM) for spinal cord stimulation, achieving focal activation at deep tissue sites with reduced surface activation and muscle co-activation.

This paper develops a statistics-driven workflow using stereoelectroencephalography to identify personalized deep brain stimulation targets through power analysis and effect size calculations.

This study shows that cortical surface electrical stimulation in awake mice initially activates L2/3 neurons and then causes prolonged inhibition, altering sensory processing and neuronal selectivity.

This paper demonstrates that graphene-polymer nanofibers can be optically stimulated to enhance electrical activity in stem cell-derived cardiomyocytes and brain organoids.

The paper introduces a high-channel-count flexible electrode for deep brain recording, capable of capturing single-unit activity from up to 128 channels.
