Micro-invasive probes for monitoring electrical and chemical neural activity in nonhuman primates

This paper develops micro-invasive probes for dual chemical and electrical neural activity recording in nonhuman primates, demonstrating long-term functionality over one year.

Aseptic, semi-sealed cranial chamber implants for chronic multi-channel neurochemical and electrophysiological neural recording in nonhuman primates

This paper describes a new neural implant that enables long-term, aseptic recording of both neurochemical and electrophysiological activity in nonhuman primates.

Synchronous Measurements of Extracellular Action Potentials and Neurochemical Activity with Carbon Fiber Electrodes in Nonhuman Primates

The paper develops a method to simultaneously measure dopamine and neuronal spikes in monkeys using carbon fiber electrodes and validates it for cell-type specific activity related to behavior.
