About

Songchao Guo is a pioneering researcher at the intersection of neuroscience and bio-robotics, whose work has fundamentally advanced the field of animal-machine interfaces. His primary research focuses on optogenetic control of rodent behavior, neural circuit modulation, and the development of brain-computer interfaces for precise "rat-robot" navigation. Guo’s most significant contributions include encoding "Stop" and "Escape" commands through optical stimulation of the central nervous system, enabling unprecedented precision in bio-robot control. His landmark 2015 study on optogenetics-based rat-robot control (38 citations) demonstrated how targeted light stimulation could reliably command specific behavioral responses, while his 2014 investigation into CaMKIIα-expressing neurons in the ventral tegmental area (14 citations) revealed how optogenetic activation of these excitatory neurons directly upregulates locomotor activity in freely behaving rats. Additionally, Guo engineered a remote constant current stimulator (9 citations) that overcame limitations of earlier voltage-based systems, delivering precise 0–1000 µA currents for reliable brain-computer interface navigation. His work bridges fundamental neuroscience—particularly the role of the VTA in motivation and motor control—with practical applications in bio-robotics, offering transformative tools for studying neural circuits and developing semi-autonomous animal-machine systems.
