Multi-Probe Micromanipulator System
Multiple silicon probes. One simple micromanipulator system.
Maximize productivity and precision for acute in-vivo recording with automated probe positioning for electrophysiology and optogenetics
Now with longer travel, higher force
The MPM Multi-Probe Micromanipulator System provides convenient, automated positioning of multiple neural probes for acute in-vivo recording. Simple to set up and operate, it is the first micro-manipulator designed specifically for use with silicon probes.
The compact design allows for independent positioning of multiple probes in the smallest space, with ample clear area for a virtual task environment. Automatically and independently move each probe to the optimum location in the brain.
- Compact size: Independently position mulitple probes in the smallest space
- Fast set-up: Fully engineered, modular apparatus space-optimized for upright or interved experiments
- Easy operation: 24 axes of automated motion controlled using a single PC window (open additional windows for more probes)
- Automated sub-micrometer probe adjustments with absolute position measurement and control
- Gross manual + fine automated control in one system
- Four-axis manual pre-positioning with repeatable stops
- Three-axis motorized fine positioning with 15 mm travel on each axis
Compact, easy-to-use system
Manipulate multiple probes in the smallest space
A mounting ring allows multiple probe arm assemblies to be positioned around the target – from one probe to eight or more. The ring mounts to standard laboratory tables with imperial or metric hole patterns. Alternatively, the arms can be inverted by mounting them to the underside of an elevated platform, maximizing clear space below the probes for animal interaction with a virtual task environment.
Each probe arm has four degrees of freedom for initial pre-adjustment. Use the displacement markings to register the location of each probe in stereotaxic coordinates and calculate the approach angle. Coming soon: Enter this information into the Virtual Coordinate System with the MPM software, removing real-time geometry puzzles from the time it takes to do a recording.
Precise motorized positioning
Each probe arm also has three axes of motorized motion for automated positioning. The motorized positioners allow precise control of x-y location and z insertion depth, automatically and independently moving each probe to the optimum location in the brain. The standard motorized positioners offer 15 mm of travel on each axis, with high force and stiffness. Learn more about the M3-LS micro stages.
The New Scale MPM System automatically and independently positions multiple silicon probes for stable acute in-vivo research including electrophysiology and optogenetics.
Designed for Silicon Probes
The MPM System is the first micromanipulator specifically designed for silicon probes. It is also compatible with tetrodes and other probes. It can be used to simultaneously position optical waveguides or optical fibers for research combining electrophysiology with optogenetic stimulation.
Probe mounting kits are available for many commercially available probes. We also offer custom probe mount design.
Protect your probes
A steel reference probe reduces setup time and minimizes risk of damage to probes during setup. Repeatable stops allow you to simply swing the probe arm up to replace the reference probe with a silicon probe, and return it to the target position.
A tech note describes the probe mounting and pre-positioning solution for the NeuroNexus A32 probe with NeuroNexus OM32 adapter. Other adapters use a similar pre-positioning technique. Get the tech note.
Intuitive PC Control Application
- Control up to eight probes in a single PC window. Open additional windows to control additional probes.
- Coarse, fine and insertion step modes
- Display of absolute and configurable relative positions
- Automated z-axis insertion – very slow with x/y movement disabled
- Multiple editable configurations – step size, speed, axis associations, etc.
- Optional joystick or other input device control (PC compatible USB-HID)
- Coming soon – Enter angle and displacement into the Virtual Coordinate System (VCS) to register probe locations in stereotaxic coordinates and calculate the approach angle of each probe.
