PlexBright Head-Mounted LED Modules

At the heart of the PlexBright® Optogenetic Stimulation System are the cost-effective and powerful PlexBright Head-Mounted LED Modules for use with our PlexBright Commutators for freely behaving animals.

 

Plexon’s Head-Mounted LED modules provide outstanding light stability and pulse characteristics are miniaturized for placement directly on an animal’s head. Our ever-expanding series of powerful, fiber-coupled PlexBright LED Modules effectively elicit responses from several opsins targeted in neuroresearch, including channelrhodopsins (ChRs), archaerhodopsins (Arch) and halorhodopsins (NpHR).

The Head-Mounted LED modules are available in Blue (465nm), Green (525nm), Lime (550nm), and Orange (620nm)

We also offer Magnetic Head-Mounted LED Modules that include a magnetic optical rotary connector that can be used with the NEW magnetic fiber stubs to relieve the torque on the implant from rotational movements such as spinning and twirling (available in blue, green, lime, and orange).

Commutators that deliver power to the LEDs as they spin freely along with a behaving animal. These modules have recently been enhanced to feature a magnetic connection to the commutator. The new style of magnetic attachment enables faster module interchangeability. These Compact LED Modules are compatible with the PlexBright Dual LED Commutator, PlexBright Dual LED + 16 Channel Commutator for simultaneous neural recording with analog headstages, or the NEW Carousel™ Commutator for simultaneous neural recording with digital headstages.

PlexBright Starter Kits offer the initial products to get started. Kits are available in four experimental designs and with either driver (the economical kit with the LD-1 Single Channel LED Driver or the fully functional kit with the PlexBright 4 Channel Optogenetic Controller with Radiant Software).

In addition to super intensity PlexBright LED Modules, Optical Patch Cables and Commutators, the PlexBright Optogenetic Stimulation System also offers the PlexBright LD-1 Single Channel LED Driver; the more sophisticated PlexBright 4 Channel Optogenetic Controller running Radiant Software; specially designed PlexBright Fiber Stub Implants; the PlexBright Light Measurement Kit; and the PlexBright Optical Fiber Cleaning Kit to safely maintain and extend the life of the fiber tips. If your experiments include freely behaving animals, you may also be interested in learning more about the CinePlex® and CineLyzer® Behavioral Research Systems.

Your Plexon Sales Engineer is available to provide additional information and to assist you in determining what configuration might be the best choice for supporting your research.

Head-Mounted LED Modules are used in conjunction with our PlexBright Commutators (for use with freely behaving animals).

¹Power values are measured using pulsed stimulation (1 msec pulses)

*Magnetic Head-Mounted LED modules have lower values for Measured Output at the the LED module because they are made with a smaller fiber (200/230)
