We can provide three-channel and four-channel systems for studying sleep, epilepsy, and behavioral patterns in mice and rats under free movement. The EEG / EMG system uses a unique head-mounted preamplifier to obtain a very clear waveform even when the animal is in motion. The four channels have the characteristics of all three channels and an additional channel is added. The ability to configure biosensors at the same time.
The electroencephalograph of rats and mice can provide a set of professional bioelectric recording system for the study of sleep, epilepsy and general behavior paradigm of rats and mice under free movement. Using a headstage fixed to the animal's head for signal amplification, it can continuously record the ideal signal with extremely low noise even when the animal is moving.
We provide a pre-configured three-channel research system for sleep or epilepsy research. At the same time, a more flexible four-channel system can be provided, which integrates the biological probe for simultaneous recording of multiple signals. All systems support the optogenetics suite. Common applications: sleep research, epilepsy research, deep electrode recording, cortical recording, field potential, cognitive research
The prefabricated rat and mouse head holders fix the plugs connected to the EEG or EMG electrode wires to the micro board. The extra two needle electrodes are used in a 4-channel EEG configuration. Prefabricated fixture components reduce surgical time and allow multiple arrangements of electrodes, providing a plug-and-play wire connection.
The front put is secured to the animal's head with a screw.
High-pass filtering: 0.5Hz EEG, 10Hz EMG (sleep study); or 1.0Hz EEG, 10Hz EMG (epilepsy)
Gain: X100 (sleep), X10 (epilepsy)
An 18-inch cable is connected to the preamp via a wheel. The outer layer of the wires in the cable is protected by a layer of metal spring wire.
An anti-winding wheel is fixed on the top of the animal cage. The two plugs of the runner are arranged to allow the movable lever to be balanced in different directions.
A data modulation and acquisition device (DCAS) provided by the system provides secondary amplification, filtering, and digitization functions. Finally, the data is transmitted to the computer running the acquisition analysis software via a USB cable.

Brain chemical real-time monitoring module:
环伏安 法(FSCV)电化学检测系统，用于儿茶酚胺(ie, dopamine, norepinephrine, and serotonin)的测量。 Fast scanning cyclic voltammetry (FSCV) electrochemical detection system for the measurement of catecholamines (ie, dopamine, norepinephrine, and serotonin). Can be used to measure animals in free awake state. The telemetry system is suitable for mice.
Pinnacle's FAST SCAN CYCLIC VOLTAMMETRY (FSCV) SYSTEM is specifically designed to simplify the measurement of catecholamines (ie, dopamine, norepinephrine, and serotonin). Pinnacle offers turn-key systems for both mice and rats. Both the wireless rat system and the tethered mouse system use carbon fiber sensors to enable short-term measurement in the brains of freely moving animals .
HOW IT WORKS
Biogenic amine levels are detected by rapidly cycling a voltage across an implanted carbon fiber sensor and measuring the resulting current. Our systems can measure spontaneous sub-second neurotransmitter release events while conducting detailed behavioral studies. Both the wireless and tethered systems sweep from 250 to 400 V / s in a user-selectable range spanning -1.1 to +1.3 V. All systems have built-in support for controlling an external stimulus.
l Voltage Span: -1.1 V to +1.3 V
l Range: 250 – 400 V / s
l Sweeps / second: 5-10
l Points / sweep: 1000
Dopamine (blue), serotonin (green), and norepinephrine (pink) have specific voltammogram profiles when detected by FSCV.
The TETHERED FAST SCAN CYCLIC VOLTAMMETRY (FSCV) SYSTEM allows researchers to harness the powerful genetics of the mouse model to address underlying mechanisms of biogenic neurotransmitter release and function. A headmounted FSCV board sends signals through a low-torque commutator to an interface box that streams data to the host PC. The system comes with Pinnacle's FREE 8500 software.
1. The FSCV interface box provides access to stimulus lines and transmit data to PAL-8500 software.
2. A low-torque commutator, which is mounted above the cage, allows for unencumbered freedom of movement.
3. Signals are amplified and filtered at the head of the animal using our headstage, which ensures the delivery of clean, artifact-free data.
4. Stereotaxically placed guide cannulas allow easy insertion of carbon fiber sensors. Headmounts are affixed to the skull with dental acrylic and act as a connection port for the headstage.
Pinnacle's FSCV system uses CARBON FIBER SENSORS (CFSs) to measure the presence of dopamine and other catecholamines in the brains of freely moving animals. Our sensor is a 34 µm diameter carbon fiber housed in a silica sheath that extends 0.5 mm beyond the end of the silica. All Pinnacle CFSs require an Ag / AgCl reference electrode.
Our sensor is a 34 um diameter carbon fiber housed in a silica sheath that extends 0.5 mm beyond the end of the silica.
Carbon fiber sensors are ordered by cannula type and whether the researcher needs to remove them from the cannula for post-calibration. CFS-F sensors are fixed in the cannula and cannot be removed for post-calibration.
The FSCV system includes Pinnacle's FREE PAL-8500 software, which supports traditional, short recording paradigms (recordings of two minutes or less) as well as longer-term recordings that use an extended continuous mode. Furthermore, the suite supports integrated, synchronized video recording , which allows monitoring of animal behavior simultaneously with biogenic amine release.
Additional features of this software include:
• Background Subtraction
• 3D Visualization
• User-Selectable Filters
• Heat Maps
• Animated Voltammograms
• Export to Third-Party Packages
