Motorized XYZ-Manipulator
Positioning system for neurophysiological applications
This device has three axis motorized with precision linear motors. The Z-axis is equipped with an electrode holder which can be customized.
A Thomas Pencil Microdrive can be mounted to the Z-axis of the motorized XYZ-manipulator (see figure 1). This Pencil Microdrive is optional available and can move a Thomas microelectrode (single electrode, tetrode, heptode or multitrode) with an axial resolution of 1µm into neural tissue.
Key features:- X-, Y– and Z-axis motorized
- No powered-off mode, record while electrode is moving
- Thomas pencil drive can be mounted to the manipulator
- Other electrode holders are available on request
- System for slice recording applications is available
- Manipulator is delivered with motor control unit and software
- Small and lightweight
- Plug-and-play technology
- Low cost
| Data | |
| Electrode travel: | 10.000µm |
| Resolution: | 1µm in z-axis, x- and y-axis with a grid in primate recording chambers, or xy-manipulator in small animal stereotaxy |
| Electrodes: | Standard electrodes for neurophysiology, not limited to Thomas electrodes (please feel free to ask for the electrodes that you plan to use!) |
| Preamplifier: | Not part of delivery, but available on request |
In contrast to other motorized XYZ manipulators presently available on the market, we do not use piezo steppers as actuators. Therefore we do not need a powered-off mode for recording neural signals. With the Thomas system one can move the electrode into brain tissue and record simultaneously without noise pickup from the actuators!
By using the Thomas pencil drive together with the motorized XYZ-manipulator we can offer 4 motorized axis that can be controlled independently from each other by a motor control software which is part of system delivery.
The motorized XYZ-manipulator is small and lightweight. We can customize the device to fulfill different scientific requirements.
For example the motorized XYZ-manipulator is used in multi-slice recording setups together with Thomas pencil drives or stimulation electrode holders.
