    FAST SCAN CYCLIC VOLTAMMETRY SYSTEM

    Pinnacle’s 青青草视频在线寓目_青青草2018网址最新版_青青草免费版佳构视频在线寓目 is specifically designed to simplify the measurement of catecholamines (i.e., 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 resultant 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

    Analysis

    99热视频那只要佳构国产,99热在线视频寓目免费,99热久久免费视频在线,亚洲视频99热佳构在线播放


    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 transmits 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.

     




    CARBON FIBER


    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.

    CARBON FIBER SENSORS

    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。



    FSCV PAL-8500 SOFTWARE PACKAGE

    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
