StartleMonitor^TM System

When we began development of our StartleMonitor system we were determined to set a new standard for performance, reliability and ease of use. After several years of extensive research and development we have finally reached that goal. Our design staff of 4 engineers used their combined experience of 40 years in behavior equipment to create this rugged new system. And it is with great pride and excitement we offer the Startle Monitor system for your consideration. Superior acoustic design helps to eliminate system induced variability. We’ve designed our system with high precision circuitry; providing +/- 1 dB accuracy at all points of the scale (57-120 dB) and from chamber to chamber! Our cabinets have the highest sound attenuation available on the market, -35dB. Older systems commonly use tubes for restraint. It has been well established that tubes induce stress and stress affects startle. In response to this problem we designed a new restraint mechanism that greatly reduces the stress on the subject. Call us for details.
StartleMonitor - The best choice for:
Transgenic & Mutant mouse studies! The Startle Monitor system has been specially designed for use with transgenic mice. We’ve incorporated critical features into the system such as ambient vibration immunity and extremely high sensitivity for the small responses of mice.
Pre-pulse Inhibition The ability to run pre-pulse inhibition trials is already a part of the system. Simple Windows commands help you easily create these trials. Cross Modal Pre-pulse Inhibition Gap Detection Similar to pre-pulse inhibition, but with a decrease or absence of sound. This mode of testing is also built-in. Standard Acoustic Trials Exceptional acoustic characteristics for classic startle reflex. Fear Potentiated Options All components needed for a complete fear potentiated operation. Habituation Trials Tactile (air puff) Startle Reflex Latin Square Presentation of Trials

Startle Monitor Key Features Superior Acoustic Design!

Helping to Eliminate System Induced Variability Startle research has long had a reputation for high subject-to-subject variability. Acoustic startle responses are tied directly to the accuracy of the noise stimulus and the quality of the ambient noise control. We’ve designed our system with high precision circuitry, providing +/- 1 dB accuracy at all points of the scale (57-120 dB) and from chamber to chamber! Startle will always have variability because of the nature of startle response. However, we set out to eliminate known system weaknesses which have caused unnecessary variability.
35 Decibels of Attenuation! Our cabinets have the highest sound attenuation available on the market. The closest competition provides only 22-25 dB. Recall that each decibel represents a multiple of 10. Therefore, an increase of more than 10 decibels is very significant. No Acoustic Calibration or Strange Tables to Create or Use Simple and direct! Because of the outstanding attenuation, you are able to use noise levels down to 57 dB! You are no longer limited to 65 dB as a lower limit. And our system is factory calibrated so all you do is enter the desired level. No calibration tables to create for each station nor do you use an arbitrary number table as with some systems. You simply enter the level you want and that’s it! Microsoft® Windows® NT/2000 Based System Like all of our products, the Startle Monitor system is Windows NT/2000 compatible. There is no PC card to install in your computer. All that is required is a serial cable between your computer and the control chassis. The control chassis can handle up to eight stations using a single PC!
Startle Monitor Key Features New restraint design removes stress induced by older tube method:
Stress Affects Behavior & Tubes Induce Stress! Older systems use a design placing animals into tubes. And tubes have long been known to create stress. Our new restraint design contains the subject consistently over the sensing transducer while still providing an ample sensation of freedom of movement. The key is in the adjustable ceiling which allows the subject increased headroom without permitting ambulations. Durability The feet on the transducer assembly have been moved to a special anchor plate. And because we use a piezo disk and not a delicate load cell, the assembly is rugged and not easily affected by user handling. Calibrated in Newtons, not Abitrary Units! A single pulse calibrator allows your data to be reported in milli Newtons. Now you can have confidence about comparing studies. There is no longer a concern over the systems original setting. Additionallly, the high stability of the system helps reduce the number of times needed to check calibration. Higher Throughput With Less Cleaning Time We listened to the comments of experienced scientists and research assistants who’ve suffered for years with cleaning problems. Active labs report spending over an hour just cleaning large systems. Our unique refuse tray is built righ into the sensing tray to gather and contain waste. For cleaning, you simply remove the sensing plate, rinse it and you’re ready to proceed with the next session. We want you performing studies, not cleaning refuse. Easy to Use Windows NT/2000 Based Software The StartleMonitor software has been modeled after our popular MotorMonitor program, with concise yet flexible input screens. As shown here we’ve created a single input screen that will do most of your work. You can input session parameters, order your trial list, input subject information, edit trials, edit sessions, and finally run any desired session you chose all from this screen! Simple Data Reduction! First select the file to reduce and then just give it an output file name. You’re done! Compact Cabinet to Help Conserve Your Lab Space We realize how precious lab space can be so we made our cabinet design the smallest in the industry. You can place twice as many cabinets in the same space and still have a system that outperforms them all!
Startle Monitor Options: Potentiated Startle Reflex Kit The optional Potentiated Startle Reflex kit adds foot shock and a conditioning stimulus for potentiated startle studies. The conditioning stimulus can be acoustic, light, tactile or user-supplied. Tactile Kit The Tactile Kit provides air puff stimulation to rats and mice.
