CLOCKLAB ADDITIONAL 56-CHANNEL INTERFACE (448 MAXIMUM CHANNELS)
Contact our Behavioral Research Specialists for more information

ClockLab's 56-channel interface is a small (8" wide) box that connects to the computer via a USB cable. Using a USB hub, up to 8 interface boxes can be connected to a single computer, for 448 input channels.

Each interface box has on its face 8 RJ-45, or ethernet-style, connectors. These connectors have 8 pins. As shown in the diagram below, one pin serves as a ground, and the other as inputs for 7 different channels. Each switch (or other input device, such as an infrared motion detector) is simply connected between the ground and one of the signal pins. When the switch closes, the program detects an event on the corresponding input channel.

Each input channel can be used to count events on a switch or other detector. Or it can be configured to detect the lights in the experimental room or chamber. For light detection, a photodetector (provided) is connected to the input channel, and the program is configured to store that channel's data as the light cycle for a specified set of counting channels.

Also availalbe are simple breakout boxes that convert each RJ-45 input to 7 pairs of banana jacks for direct connection to switches and light detectors.
7-CHANNEL BREAKOUT BOX FOR CLOCKLAB
Contact our Behavioral Research Specialists for more information

Used to convert each RJ-45 input to 7 pairs of banana jacks for direct connection to switches and light detectors.
MOUSE CAGE WITH RUNNING WHEEL
Contact our Behavioral Research Specialists for more information

The mouse cage design was developed in a leading circadian rhythms lab and has been found to be extremely reliable, easy to clean and inexpensive. The switch has two banana plugs at the upper left and lower right corners of black switch housing. These are not electrically connected, but plug into the red banana jacks in the cage wall to hold the switch in place. The switch is therefore easily removable for cage cleaning. The switch lever arm projects out to the right and passes just below the wheel axle. The cam on the axle hits the lever arm as the wheel rotates, depressing the switch button once per revolution.

Data Analysis and Collection for Circadian Biology

Does it take you longer than 30 seconds to measure phase shifts? If so, ClockLab, the industry standard for the collection and analysis of circadian activity data, can help. It combines a point-and-click interface with state-of-the-art algorithms. Embedded controls turn each graph into a powerful interactive tool for data analysis. Our users enjoy ClockLab's speed and convenience. ClockLab's Analysis program has been applied to mice, hamsters, rats, drosophila, humans, bees, algae, Eurasion Lynx in the zoo, radio-tagged squirrels in the wilds of Alaska, horseshoe crabs, and soil chemistry signals from the Mars Viking Lander.

ClockLab's data collection program incorporates a large array of features at reasonable cost:
    Up to 448 channels on a desktop or laptop machine
    USB interface for instant setup
    Integrated light control and light recording
    High-density switch connections
    Remote data access via internet
    Record switches, motion detectors, Minimitter ER-4000's
Paste actograms and other plots into presentation graphics programs like PowerPoint, Illustrator or Photoshop. Every graph is completely editable.
Automated detection of activity onsets and offsets makes it possible to
    Measure phase shifts
    Measure mean alpha
    Predict future activity onsets... all with a few mouse clicks.
Zoomable actograms for easy navigation through long records. Just drag on an interesting part of the actogram to zoom in. Then click to display the periodogram, FFT or activity profile for the chosen data segment.
Chi-squared periodograms, activity profiles, FFT's and auto-correlograms.
Bout anlaysis.
Export all data and analyses to spreadsheet files.
Access data in many formats, including...ClockLab format, Stanford Software's Chronobiology Kit, Actiwatch, Dataquest, Minimitter, Trikinetics and others.
Extensive batch processing capabilities for printing and analysis.
Windows compatible.

Analysis program (Circadian Toolbox)

A single-computer license for the analysis program can be purchased on its own. It requires the purchase of Matlab (The Mathworks, Natick, MA). Only the basic Matlab is required. Toolboxes, simulink, the compilers and Excel Builder are not required. The Student verison is not recommended and will not work for large data files.

System Requirements

The data analysis system runs on Windows 2000/XP and requires only the basic MATLAB program (no toolboxes or Simulink necessary) from The MathWorks, Inc. if your institution does not already have a site license available.

Data collection requires a computer running Windows 2000/XP with a clock speed of 500 MHz or greater and 128 MB memory. Monitor resolution of 1024x768 or better. Zip drive , flash memory stick or network connection recommended for accessing files during data collection.
LIGHT SENSOR
Contact our Behavioral Research Specialists for more information

The ACT-554 will detect the presence of light.  Use in ClockLab systems where the light cycle is being controlled to provide a record that the lights were on and off as programmed.
