ELECTRODE DRIVE (ELECTRODE POSITIONING SYSTEM)

Procurement Summary

This action is for procurement of NAN Electrode Drive (Electrode Positioning System). The objective of this purchase is to enhance our comprehension of the neural mechanisms underlying visual perception. To achieve this, our research studies awake non-human primates with concurrent electrophysiological recordings and electrical stimulation in the targeted brain region during a visual perception task to address gaps in the existing literature. This research necessitates the simultaneous recording from four electrodes within the specified brain region. These electrodes must be designed to reach ventral brain regions without veering from their intended path during their descent through the brain. Furthermore, they must offer flexibility in their placement within a recording chamber, allowing for arbitrary reconfiguration as needed. The UNCB needs a specialized electrode driver that provides precision, consistency, and accuracy the NAN electrode drive system offers. Salient characteristics for this requirement include; One (1) NAN Electrode Drive System Set-up for chamber recordings: four channel controller with software included, Adapter custom fitted for chamber (24.16 mm for base), four channel base custom fitted for chamber, NAN electrode tower, grid for 23-gauge tubing (1mm hole spacing), coarse movement system, neuropixel motorized and manual arm, neuropixel holder, guide tube clamp for neuropixel, 8 guide tubes for neuropixel (7mm x 5mm). Additionally, it must have: - Modular system with the capacity to record up to 16 channels - Reliable and stable recordings over extended time periods - Effective noise reduction even during electrode movement - Flexibility and consistency in electrode positioning within the XY plane - High-resolution capabilities of up to one micron - Precise electrode placement facilitated by direct motor-electrode coupling - Adjustable electrode depth manipulation within a user-defined operational range - Controlled speed range, ranging from one to 200 microns per second - Effortless electrode replacement, requiring less than one minute per tower - Advanced controller with a user-friendly GUI, enabling communication with a 19-inch rack-mount control box through a standard interface - Lightweight design, with each tower weighing 25g and a 4-channel base weighing 35g
