Acquisition

SleepSign-Rec is a dedicated aquisition system for SleepSign.
It records analog signals such as EEG and EMG, and can also perform simultaneous video recording.
Compared to the previous version, it enables longer recording periods.
Additionally, by using the optional “Sleep Stage Closed-Loop Function,” real-time scoring and signal output to external devices based on scoring results are possible.

*SleepSign-Rec is the successor to VitalRecorder and SleepSign-Recorder.

Hardware

SleepSign data acquisition program and related hardware enable you to acquire data from analog output of your amplifier and store as digital data in a PC.

Using your acquisition system

By connecting to the BNC Connectors terminal box, you can record the analog signals output from your acquisition system.

To record analog signals, the following products are required.

Please procure the products listed in the configuration table locally.

Biotex Amplifiers

Biotex amplifiers are engineered specifically for sleep research, offering unparalleled performance and reliability in biological signal acquisition.

Traditionally, measuring biological signals such as EEG and EMG in experimental animals has been a complex and time-consuming process. Researchers were required to select, configure, and customize equipment combinations tailored to their specific measurement needs, while also establishing a noise-free recording environment—placing a substantial burden on valuable research time.
To address these challenges, we’ve developed the ideal solution: a streamlined recording system specifically engineered for sleep measurement. Featuring only the essential signals—EEG, EMG, and locomotor
activity—our system eliminates the need for complex amplifier configuration while incorporating advanced noise reduction technology.
This is the Biotex measurement device—designed to let you focus on your research, not your equipment setup.

*Currently, Biotex products are sold only in Japan and China.

• Electrode

  Electrodes are available for purchase for both mice and rats.
  Since rats are particularly stronger than mice, the rat electrodes employ a special design that is resistant to detachment by using a clutch to assist the connection strength and utilizing a SATA connector.

  

• Junction Cable

  Connect the Slip ring with the Electrode that mounted on the mouse head.
  The cable has a soft material, so it does not limit the animal behavior.
  The cable material can be selected from Nomal type or Higrade type, and the cable
  length also can be selected from 30cm or 40cm.

  

• Slip Ring

  Slip Ring rotates with the movement of the mouse or rat and prevents the cable
  from twisting.
  There are two types available: with hole and without hole type.

  • Without hole typeSL-006(22): This is the standard type. Please use this for recording normal EEG and EMG.
  • With hole typeSL-006(32) H: This type has a hole for passing wires, which is necessary for drug administration, etc. Please use this type if you want to perform continuous drug administration or stimulation using fibers, etc., on the animal during recording.
  

• Head Amplifier

  Head Amplifier is an EEG and EMG amplifier for measuring EEG and EMG of small
  animals. For models with Locomotor, the animal activity is also measured with a 3D
  infrared pyroelectric sensor.

  

• Interface cable

  Connect the Interface Box and Head Amplifier.

  

• InterFace Box

  InterFace Box supplies power to four EEG/EMG amplifiers (head amplifiers) and relays signals to the A/D converter (CONTEC/AIO-161601UE3-PE). This device has a connector for direct connection to the A/D converter. One unit can supply power to up to four head amplifiers.

  

• Calibrator

  Output ±100㎶signal for calibration of Amplifier.

  

• Cage for Mouse

  A mouse breeding cage for experiments.

  

Closed Loop Option

ClosedLoop-option is a function that estimates sleep stages in real time from EEG and EMG signals, while simultaneously outputting a signal when the subject transitions to a specified sleep stage.

Feature

• Controls optogenetics and various other external devices.
• Output feedback stimuli are non-isolated open-collector outputs.
• Up to four subjects can be individually controlled from a single PC.

To output a trigger signal, the following product is required.
