Near Infrared (NIR) Video Fear Conditioning


MED-VFC-NIR-M (Mouse)
MED-VFC-NIR-R (Rat)

Now You Can Measure the Freeze Response in “Total Darkness”
C57BL6 Mouse Under Visible Lighting Conditions
C57BL6 Mouse Under NIR Lighting Conditions

Eliminate the need for bright visible light by taking advantage of our new NIR-based imaging system. Bright visible lighting yields uniform illumination, which is essential for high quality, low-noise video recording of animal behavior. However, in some instances, this bright illumination may adversely impact animal behavior by serving as a contextual cue to the animal.

Our latest addition to our Fear Conditioning Video Tracking product line was developed with this limitation in mind. NIR illumination does not impact animal behavior, yet allows high quality video recording to be made using our state-of-the-art digital camera technology.

Fear Conditioning Packages (MED- VFC-NIR-M & MED VFC-R) Include:

  • Contextual Inserts
  • Video Camera
  • Conditioning Chamber with Stainless-steel Grid Floor and Quick Disconnect Harness
  • Programmable Tone Generator and Speaker
  • Electric Aversive Stimulator/Scrambler
  • Houselight
  • Sound-attenuating Cubicle with Exhaust Fan and Near Infrared/Visible Lighting System




Components for Fear Conditioning Test Packages


ENV-414S
Standalone Aversive Stimulator/Scrambler

Add aversive stimulation to virtually any experiment easily with the ENV-414S. This unit delivers an adjustable, scrambled aversive stimulation within one of two ranges, 0 to 1 or 0 to 5 MA. The grid rod floor connects to the aversive stimulator system by a standard DB-9 plug and allows for constant current levels even if a connection to a grid rod is lost. This unit has a self-contained power supply and may be controlled by a 28 V DC to ground signal, a 5 volt TTL signal, or a remote switch closure, thus allowing maximum flexibility in standalone application or when connected to existing equipment. Line voltage: 115 V AC, 60 Hz.

ENV-414SA
Standalone Aversive Stimulator/Scrambler

This unit is identical to the ENV-414S with the exception that it operates from 230 V AC, 50 Hz. CE testing and calibration is provided with all units shipped to the European Community.
