Typical Neurophysiology WorkstationsTDT’s Neurophysiology Workstations each include a powerful real-time processor and one or more optically isolated, battery-powered preamplifiers. This combination delivers low noise, high performance, and the unparalleled flexibility of a user programmable real-time DSP. Every channel is simultaneously sampled and user-specific processing is performed on the fly. Our OpenEx software suite is included to provide flexible, real-time control of multi-channel experiments from a graphical software interface. Systems available up to 256 channels. RZ2 Multi-Channel Neurophysiology Workstation RZ5D Multi-Channel Neurophysiology Workstation TDT’s RZ5D Multi-Channel Neurophysiology Workstation acquires, processes, and analyzes neural spikes on our RZ5D multiprocessor base station. This sample system includes a 32 channel digital headstage and headstage manifold to create a complete 32-channel recording solution. The RZ5D can also be used with the PZ3 for up to 64 channels of ECOG recordings or with the IZ2 to serve as a complete microstimulation system.
High Channel Count Systems This system is typical of our high channel count recording systems. It features two of our powerhouse RZ2 BioAmp Processors with fast fiber optic connections, two 256-channel Z-series preamplifiers, and a high throughput data streamer for a complete 512 channel recording system. Systems can be configured for up to 1024 channels and can be equipped with any combination of high channel count headstages to match user electrode configurations. Integrated Stimulus GenerationNeurophysiology workstations can easily be expanded to add complete integrated stimulus production capabilities. System 3 devices can be used to generate acoustic, vibrotactile, or vestibular stimulus waveforms; control visual stimulus generators or olfactometers; or generate electrical microstimulation waveforms. Integrated Auditory Stimulus Generation When added to an existing workstation, an RZ6-A can offer two channels of synchronized very high-fidelity, wide bandwidth, acoustic stimulation complete with programmable attenuation and drivers for a variety of transducers, including magnetic speakers or electrostatic speakers. Microstimulation System The RZ5D Processor combines the power of user programmable digital signal processing and an optimized communications interface with support for the IZ2 stimulator. The system is a programmable microstimulator with excellent dynamic range for wide bandwidth electrical stimulation, up to 128 channels. Workstation Addition for Awake, Behaving ProtocolsAdd a motorized commutator to your system as part of a complete solution for research with awake, behaving subjects. Available with 16, 32, or 64-channels. |
The modular and flexible nature of TDT System 3 Processors makes it easy to expand or completely change the functionality of your workstation—often with little or no additional equipment.
