Typical Neurophysiology Workstations

TDT’s Neurophysiology Workstations each include a powerful real-time processor and one or more multi-channel preamplifiers. This combination delivers the low noise of an optically isolated, battery-powered preamplifier and the 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.

Z-Series Multi-Channel Neurophysiology Workstation


Z-Series Neurophysiology Workstations represent our highest channel count recording systems to date. Offering to up to 256 channels, this system features a new fast fiber optic connection supporting sampling rates up to ~50 kHz. This sample system includes two 64-channel acute headstages and a 128-channel Z-Series Preamplifier to create a complete 128 channel recording solution.

Multi-Channel Neurophysiology Workstation

TDT’s Multi-Channel Neurophysiology Workstation acquires, processes, and analyzes neural spikes on our Pentusa multiprocessor base station. Pentusa-compatible preamplifiers digitize incoming signals at ~25 kHz with 16-bit precision. Our modular BioAmp design provides unprecedented system scalability (from 4 to 64 channels). This sample system includes two 16-channel acute headstages and two 16-channel Medusa PreAmps to create a complete 32-channel recording solution.

Integrated Stimulus Generation

Neurophysiology 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, the components listed below offer two channels of synchronized very high-fidelity, wide bandwidth, acoustic stimulation complete with programmable attenuation and ultrasonic transducers.
