Invilog manufactures a very special Battery Operated Stimulus Isolation Unit (SIU A100), which produces electrical stimulation with a minimal noise. This SIU is working under the control of the FCV Analyzer (part of the Invilog In Vivo Voltammetry Setup) or with any computer controlled digital-to-analogue card (pulse generator or stimulator) which is able to produce 0-10 volts pulses. A voltage applied to the input determines the intensity of electrically isolated current (or voltage) on the stimulating electrodes.

A low noise stimulation is especially important when after registration of dopamine transients, we apply a low intensity electrical stimulation on the dopaminergic cells or pathways to obtain stimulated dopamine release. The resulting electrochemical signals are used as a template for automatic recognition of the dopamine transients by Invilog’s software package.

 

The main features of the SIU 100:

– 100 Volts or
– 10 mA current stabilized maximal output
– battery power
– clean, noise-free stimulation
– any shape stimulation output in DC mode
– mono or bipolar pulses in AC mode
– works with any type of stimulating electrodes
– perfect match to any modern neurophysiology
software with programmable stimulator
– delivers precise current for depolarizing, marking,
or lesions
– indicates electrode malfunction
– controls batteries and shows which one should
be replaced
– very compact (18 x 12 x 6 cm)

 

Applications

– in in vivo stimulation for cells, pathways, nuclei,
muscles, and transcutaneous stimulation
– in in vitro stimulation for cells, tissues, and organs
– in behavioral tests for grid floor stimulation
