iS9 Aversive Stimulator

The iS9 generates small electrical currents for standard behavioral conditioning experiments, such as startle and Pavlovian fear response. Timing is precisely controlled for pairing the stim with other sensory cues or behavioral events. The iS9 is compatible with 3rd party behavioral boxes (Med Associates, Lafayette, and Harvard Apparatus).

  • Deliver current from 0 mA - 2.5 mA in 0.01 mA steps to each of 9 metal floor grids in rapid succession.
  • Detect spout licks with built-in touch sensors (decoupled at stimulation to avoid false responses).
  • Detect null events when stimuli fail to reach the subject.
  • Automatically time-stamp stimulus and behavioral event information for on- and off-line analysis.

See the Hardware Manual for information on iS9 technical specifications.
