Published Workflows
Objective: Build an autonomous in vitro neuronal culture platform that integrates incubation, electrophysiology, and fluidic exchange so environmental variables and medium composition can be precisely controlled while neuronal activity is stimulated and recorded.
Why it works: The platform combines environmental control, electrophysiological stimulation and recording, and automated perfusion in one system, allowing perturbation of culture conditions while directly measuring neuronal spiking responses.
