The new Modular Insertion System (MIS) will enable positioning of up to 24 Neuropixels probes, along with microscope modules for visualization and laser modules for optogenetics.
Victor, NY – The Allen Institute for Neural Dynamics has selected New Scale Technologies as its licensee for its next-generation silicon probe insertion system for brain-wide acute in vivo electrophysiology. The new Modular Insertion System (MIS) expands upon its predecessor, developed as part of the Allen Brain Observatory, to enable researchers to study areas across the entire brain with greater flexibility.
The Allen Brain Observatory, in an effort to standardize the collection of physiology data from the mouse visual system, included an electrophysiology recording platform based on New Scale’s M3-LS-3.4-15-XYZ Linear Smart Stages and imec’s Neuropixels probes. Neuropixels probes allow researchers to study the electrical activity of neurons as they fire in live animals, giving researchers insights into how the brain processes information. New Scale Smart Stages provide precise positioning of these compact, high-density probes.
The MIS advances the state of the art in probe positioning to facilitate a wider range of experiments.
The MIS features three standard module options: a probe module and a laser module for optogenetics, both using New Scale’s linear smart stages for precise 3-axis positioning and a microscope module for visualization. Pictured is an MIS with 4 probe modules, 1-laser module, and 1-microscope module.
“Our goal with the MIS is to provide more flexible approach angles, enable the insertion of more probes as recording devices become smaller, provide more open space for behavioral hardware, and allow for easier maintenance during and between experiments,” says Josh Siegle, Senior Scientist at the Allen Institute for Neural Dynamics.

New Scale’s linear smart stages enable three axes of motorized motion for each Neuropixels probe in the MIS, with up to 24 probes possible. The precision micro stages allow precise control of x-y placement and slow, automated insertion control.
“Our proprietary and patented piezoelectric motor and integrated control electronics allow for the smallest possible total mechatronics system size,” says David Henderson, CEO and Founder at New Scale Technologies. “These miniature linear motion modules enable researchers to pack more probes into a much smaller space than is possible with other motorized positioning systems for neuroscience, while enabling independent and automated control of each motorized axis.”
This license will allow other leading neuroscience laboratories to readily adopt the same hardware used at the Allen Institute, which will accelerate research progress and catalyze breakthroughs. The commercial license allows the Allen Institute to leverage New Scale’s expertise in motion, alignment, fixturing and manufacturing, ensuring that each MIS is optimized for accurate, repeatable positioning of probes.
New Scale Technologies will deliver the first MIS to the Allen Institute in Q1 2024, with commercial availability in Q3 2024.
New Scale’s standard Multi-Probe Micromanipulator (MPM) System is available now for researchers working on acute in-vivo recording with multiple silicon probes, or seeking to maximize productivity and precision with automated probe positioning. The MPM System is the first micro-manipulator designed specifically for use with silicon neural probes. It supports neural probes from imec Neuropixels, NeuroNexus, Cambridge Neurotech and more. The compact hardware design enables independent positioning – and simultaneous insertion – of multiple probes in the smallest space, with ample clear area for a virtual task environment.
New Scale’s MPM System Pathfinder Software with virtual coordinate system (VCS) enables simulation, planning, debugging, and repeatable execution of experiments with greater ease and accuracy. All probes move in a common stereotactic coordinate space. Visualization of real-time probe locations, and monitoring of brain activity during insertion, is made possible through integration with open-source trajectory planning and data acquisition apps, allowing researchers to view physiology and anatomy side by side during probe insertion and neural recording.

About Allen Institute for Neural Dynamics
Launched in 2021, the Allen Institute for Neural Dynamics is a division of the Allen Institute (alleninstitute.org), an independent, 501(c)(3) nonprofit medical research organization founded by Paul G. Allen in 2003. The Allen Institute for Neural Dynamics is dedicated to answering fundamental questions about brain dynamics at the level of individual neurons, and the whole brain, to reveal how we interpret our environments to make decisions. Knowledge, data, and tools created by the Institute will be publicly shared to advance the field’s understanding of brain function and support the development of therapies for brain diseases and disorders.
