ARIS – Electrophysiology Workstation
ARIS is a multifunctional hardware solution for extracellular recording. It was designed with compactness and utility in mind to offer the researchers a powerful electronic tool.
ARIS offers a state-of-the-art workstation for in-vivo electrophysiology.
All in one
- Amplification, conditioning and acquisition of neuronal signals
- Programmable current stimulus generator
- Impedance measurement module
ARIS perfectly integrates in a computerized laboratory setting, and can also be used only as a companion tool in a hardware-exclusive recording or stimulation arrangement. Accordingly, it offers two independent operation modesPC-Control and Manual.
ARIS incorporates even the preamplifier module and connects directly to a laptop or desktop computer.
Computer controlled electrophysiology research
This equipment was designed especially for optimal amplification and acquisition of extracellular neuronal signalssingle-unit potentials (2 channels) and local field potentials (2 channels). The integrated data card ensures full computer controlchannel selection, switching of operation modes (recording, stimulation, impedance), programmable generation of stimulus waveforms of amplitudes up to 1mA @ 250V.
Clean signal
The differential input recording channels were designed with care to guarantee maximal immunity to environmental noise. The steep response of the 4th order low-pass and high-pass filters were optimally pre-tuned to ensure a virtually hands-free operation.
Direct impedance test
Measurement of microelectrode impedances up to 2MW is realized on-the-fly based on the voltage feedback of the 1nA sinusoidal signal sent to the preparation.
Computer controlled stimulation current
The stimulation current is precisely generated by the data card with no additional processing burden on the connected computer. Repetitive current pulse trains or lesioning/marking constant current are supported.
No cable reconnection
ARIS is capable of no-electrode-touch switching of operation modesrecording, stimulation, impedance testing. That is, the same preparation cable remains in place during the entire experiment.
Fully computer controlled or stand-alone
When operated through your laptop or desktop computer via the neuro-Guide software, ARIS employs not more than three connectors and cables (preparation connections and computer connection), and no other frontal panel auxiliaries. Actually, ARIS was designed for full flexibility, being able to operate in two independent modes“PC-Control”, and “Manual”. Switching from Manual to PC-Control is realized automatically when the computer cable is connected, and this condition is indicated by a frontal LED. This allows reusing your existing laboratory equipment in various combinations, for instance:
- transforming an external TTL signal into a stimulation current deliverable by ARIS,
- using ARIS as a programmable stimulus generator only,
- using ARIS for signal amplification and conditioning only,
- generating lesioning/marking current directly from ARIS’s frontal panel, etc.
