Abstract

The development of novel neurotechnologies for treating refractory neuropsychiatry disorders depends on understanding and manipulating the dynamics of neural circuits across large-scale brain networks. The mesolimbic pathway plays an essential role in reward processing and mood regulation and disorders of this pathway underlie many neuropsychiatric disorders. Here, we present the design of a customized semi-chronic microdrive array that precisely targets the anatomical structures of non-human primate (NHP) mesolimbic and basal ganglia systems. We present an integrated experimental paradigm that uses this device to map and manipulate large-scale neural circuits. The system combines electrophysiology, spatiotemporal multisite patterned intracortical microstimulation (ICMS), and diffusion tractography. We propose that this system provides a flexible platform for exploring and identifying neural signatures which can serve as novel targets for closed-loop stimulation in the clinical treatment of neuropsychiatric disorders.
