The "LKC" is a lick microstructure analysis system that allows for re-analysis multiple times by changing the time parameters during analysis. It captures the licking behavior of mice and retrieves it within the controller. From that information, it analyzes data on BURST and CLUSTER. This analysis information enables the understanding of the degree of preference in animals. While it is primarily based on a system with four cages, control of multiple units is also possible. 【Features】 ■ Captures the licking behavior of mice and retrieves it within the controller ■ Analyzes data on BURST and CLUSTER ■ Enables understanding of the degree of preference in animals through analysis information ■ Control of multiple units is possible ■ Allows for changes in time parameters and re-analysis *For more details, please refer to the PDF document or feel free to contact us.

The "LKT-16/LKT-8" is a 16-bottle/8-bottle licking test device that can be used for the preference evaluation of taste components. With an electric positioning system and an opening and closing mechanism, it allows for taste tests of up to 16 or 8 different flavors. It can accommodate multiple units, making it suitable for testing subtle differences in taste. Additionally, you can select any number of units and present multiple sets in a random order. 【Features】 - Available in a 16-bottle type and a compact 8-bottle type - Suitable for testing subtle differences in taste due to the ability to accommodate multiple units - Allows selection of any number of units and presentation of multiple sets in random order - Latency, lick count, and the interval time between each lick are recorded in a text file *For more details, please refer to the PDF document or feel free to contact us.

The "LKP2" records licking behavior as an event, making it a choice preference experiment system capable of analyzing and evaluating preferences in a short testing time. Cages are available for both mice and rats. Measurements consist of recording the count of licks per second, which is displayed as a bar graph on the PC software screen. This allows not only the count numbers indicating preference to be recorded as data, but also to be visually represented clearly on the screen. 【Features】 ■ Records licking behavior as events ■ Enables analysis and evaluation of preferences in a short testing time ■ Records the count of licks per second ■ Measurement time can accommodate both short and long durations ■ Comes with a dedicated bottle for short tests, and larger bottles can be used for longer tests *For more details, please refer to the PDF document or feel free to contact us.

The "FC System" is a device used for conducting experiments on fear conditioning and contextual learning. Animals are placed in a dedicated FCC cage, where they are subjected to sound, light, and electric shocks while their subtle movements are captured by "SCANET," which detects freezing behavior. By editing the freezing data while reviewing the recorded images after the experiment, it becomes possible to detect only the actual freezing instances. 【Features】 ■ Used in conjunction with the behavior analysis device SCANET ■ Conditional stimuli presented with dedicated software ■ Animal movements recorded by a camera ■ Soundproof box isolates the target animal from the surrounding environment *For more details, please refer to the PDF materials or feel free to contact us.

The "CB Series" is a communication box based on the Ogawa method. You can place a shock-avoidance plate at any position inside the communication box, allowing you to freely set up animals that receive electric shocks and those that do not for observation. Electric stimulation is sent to the grid of this product according to a schedule programmed with the programmable shock generator "SG-1000S." Please use it for research on purely psychological social stress and emotions. 【Features】 ■ Enables experiments with animals receiving shocks and those observing them ■ Capable of administering intermittent shocks or gradually increasing shocks ■ The interior has transparent partitions with fine perforations ■ Animals can see each other, and their vocalizations can reach each other's partitions ■ Available in four sizes *For more details, please refer to the PDF materials or feel free to contact us.

The "SG-1000S" is a shock generator that can respond to long-term stimulation, such as in our communication boxes. In the past, to prevent animals from getting accustomed to the current, it was necessary to manually increase the current value gradually. However, with the program or cycle mode, it is now possible to freely set the strength of the current. This helps prevent habituation and ensures that the stimulation intensity does not exceed necessary levels. 【Features】 ■ The current value can be programmed and varied. ■ It has a timer control function and can operate in cycles. ■ By changing the scramble frequency and duty ratio, effective stimulation can be programmed. ■ The current value can be set in increments of 0.01mA, minimizing the risk of excessive stimulation. ■ It has a current measurement function that allows for accurate monitoring of the flowing current value. *For more details, please refer to the PDF document or feel free to contact us.

The "Shuttle Avoidance System" is a product that measures the response rates of avoidance and escape to conditioned stimuli using a shuttle-type two-way cage. Both setting and control are conducted entirely from a computer. The software operates in a Windows environment and offers excellent usability. The system can observe up to 6 shuttle cages, and the positions of the animals are displayed on the Windows screen, allowing for tracking of animal movements even during measurements in an isolation cabinet. 【Features】 ■ Uses a shuttle-type two-way cage ■ Measures response rates of avoidance and escape to conditioned stimuli ■ Both setting and control are performed entirely from a computer ■ The software operates in a Windows environment and has excellent usability ■ The system can observe up to 6 shuttle cages *For more details, please refer to the PDF materials or feel free to contact us.

The "Urination Monitoring System" is a product that monitors rat urination in real-time and analyzes the state of "frequent urination." It is used by setting a Merck Quest weight sensor under a metabolic cage for rats. The sensor detects when a rat's urine drops down, capturing changes in urine volume to a PC. Dedicated software imports the weight sensor data to the PC, recording urine volume (weight) every second. Please utilize this for research on urination disorders caused by lifestyle-related diseases. 【Features】 ■ Detects minute changes in rat urine using a weight sensor ■ Graphical display allows for easy identification of urination start and end points ■ Suitable for research on urination disorders caused by lifestyle-related diseases *For more details, please refer to the PDF materials or feel free to contact us.
