Detecting neurotransmitters simultaneously to electrical stimulation and recording

Cover article of Micromachines on the integrity assessment of a hybrid DBS probe



Multimodal deep brain probes feature electrochemical neurotransmitter detection in addition to conventional electrical recording and stimulation capabilities. Dopamine sensing, increased channel count, and reduced electrode size for higher spatial selectivity are enabled by glassy carbon microelectrodes within a polyimide thin-film–silicone rubber hybrid assembly. Now the long outdated deep brain stimulation technology can be replaced with more advanced therapies in the future.
