Acoustic Startle Reflex Test Components

MED-ASR-PRO1

System Highlights • Connects with fewer cables due to the redesigned connection panel, programmable audio generator, and audio amplifiers. • Runs up to eight chambers with a single cabinet. • Reduces start up costs due to the one audio amplifier per chamber design and makes adding addition chambers straightforward.

PHM-255B Willott's Beverage Cup Stimulus Adapter.

PHM-255B
Startle Stimulus Adapter

Add this novel stimulus adapter and animal restraint developed by Dr. James Willott, University of South Florida, to any Startle Pro system for high throughput studies. A plastic plate attached to the PHM-250B startle platform insures consistent placement of a disposable plastic beverage cup used to hold the test animal. A sturdy plastic frame, attached to the PHM-255A platform table, holds an additional startle speaker directly above the cup. This method has allowed the Mouse Center Mutagenesis and Phenotyping project at Jackson Labs to significantly increase the number of animals tested per day.

ANL-929A-PC USB Sound Pressure Level Measurement Package *OS Compatibility/Computer Requirements: Windows 98, 2000, or XP*

This calibration package offers a level of stimulus verification and calibration unavailable with sound level meters or other startle reflex systems. The package consists of a microphone, microphone amplifier, analog-to-digital converter, USB interface, and sound pressure level software. The software display provides detailed measurements of either noise or pure tone signals. To replicate this package with traditional sound level measurement equipment would cost several thousand dollars. Med Associates has made a considerable R&D investment to make this product available to researchers. < back to top>

ENV-420
Aversive Stimulation
Current Test Package

Windows^® 98, 2000, and XP compatible

This test package is available for use with any Med Associates’ aversive stimulators. The aversive stimulation current test module connects to a USB port on the computer and two clip leads connect to the grid rods. The software supplied with this unit displays the actual current wave form, while the digital panel reads the RMS current corresponding to the aversive stimulator setting. Two ranges are provided to correspond with Med Associates’ aversive stimulators.

Add-ons for Potentiated Startle:

	ENV-414-SR Aversive Stimulator/Scrambler Module
	This dual-width, modular unit allows for easy setup of potentiated startle protocols. Up to four modules may be installed in the Tabletop Module/Interface Cabinet (SG-6080C). < back to top>

	ENV-414S-SR Stand Alone Aversive Stimulator/ Scrambler for Startle
	This self-contained, self-powered unit was designed specifically for potentiated startle. With a cycle rate of 30 Hz, aversive stimulation durations as short as 200 ms ensure stimulation across the entire floor. Order ENV-414SA-SR for 230 V, 50 Hz applications. < back to top>

	ENV-406SM-8 ENV-406SR Harness for Animal Holder
	With a DB-9 connector to connect to the ENV-414SR or ENV-414S-SR, and open end terminals to connect to the grid rod animal holder of your choosing, this harness provides the connection necessary for your experiment. < back to top>

ENV-262B-GF
ENV-262C-GF
ENV-263-GF
Grid Floor Accessory and Harness

Order individual removable grid floors to go with each acrylic animal holder, models ENV-262B, ENV-262C, and ENV-263B respectively. The floor assembly is pre-wired with a grid harness terminating in a DB-9 connector. The SG-219G-10 aversive stimulation output cable, 10.0' (3.0 m), with DB-9 connectors, must be ordered separately, but only one per aversive stimulator not one per animal holder.

PHM-258
Fluorescent Lamp Controller and

PHM-258L
Rapid Onset Fluorescent Stimulator

This new lamp controller features a high intensity light (maximum intensity of 107 lux) and rapid onset (15 microseconds). It plugs directly into one of the standard MED auxiliary ports. The adjustable fluorescent lamp controller stands 2-3/8" high and is 13-1/4" long and contains an eight watt bulb. The power supply/controller (pictured above), fits nicely inside a Med Associates Rack Mount enclosure.
