High-Definition Deep Brain Stimulation: rDBSA

The NeuroNexus rDBSA (research Deep Brain Stimulation Array) is a high-resolution research-grade device designed for precise deep brain recording and microstimulation. It is adapted from innovative clinical DBS technology and is suitable for both acute and chronic neuroscience research applications.

Key Advantages:

Versatile Applications: Available in both acute and chronic configurations.
High Resolution: 40-channel design (32 stimulation channels, 8 recording channels) allows selective and tunable microstimulation and precise neural recordings.
Small Animal Compatible: Specialized rat-sized rDBSA developed in collaboration with Daniel Ehrens at Johns Hopkins University for rodent studies.

Technical Specifications:

Electrode Site Material: Platinum
Substrate Material: Polyimide
Lead Diameter: 0.75 mm
