PlexBright Optogenetic Stimulation System

PlexBright Optogenetic Stimulation System

Optogenetic techniques provide a long sought-after level of control over neural tissue – the ability to activate or silence specific brain regions or cell types with extreme precision. In 2004, Ed Boyden and Karl Deisseroth at Stanford University collaborated with George Nagel and others to perform the work considered to be the genesis of the field now known as optogenetics.

Optogenetics employs a combination of genetic modulation and optical techniques. Cells are genetically engineered to express a light-sensitive opsin and then the engineered cells are activated with light, which results in cell activation (depolarization), inhibition (hyperpolarization), or modulation of intracellular signaling cascades. Below are a few of the most commonly used opsins:

-Channelrhodopsin-1 (ChR1) and Channelrhodopsin-2 (ChR2) cause fast depolarization of neurons (activation) when activated by blue light.

-Wild-type halorhodopsin, known as NpHR, causes inhibition (hyperpolarization) of the cell when triggered with yellow light.

-Archaerhodopsin-3 (Arch) inhibits (hyperpolarizes) the cell when triggered by green-yellow light.

The tools available for optogenetics have broadly expanded and now include proteins that are diverse in their ionic selectivity, spectral sensitivity, and temporal resolution. Researchers can also achieve greater specificity by manipulating the illumination (target certain regions for spatial specificity or pulse light for temporal resolution) and by limiting genetic modifications to certain cell types.

Plexon offers a powerful LED based optogenetic stimulation system that provides stable light output, outstanding temporal precision, and fewer safety concerns as compared to laser-based systems.

Feature	Specifications and Options	Remarks

Kits are available in four experimental design set-ups and with either driver (the 4 Channel Optogenetic Controller with Radiant Software or the LD-1 Single-Channel LED Driver).
Optogenetic drivers	- PlexBright 4 Channel Optogenetic Controller, or - PlexBright LD-1 Single Channel LED Driver.	The PlexBright 4 Channel Optogenetic Controller is a multichannel, pattern generating, software controlled device, while the PlexBright LD-1 Single Channel LED Driver is a more economical alternative.
Compatible Light sources	LEDs or lasers
Number of PlexBright LED Modules simultaneously controlled per channel	1 or 2	Outputs on either driver/controller can operate a single PlexBright LED Module or two in which identical parameters are desired for both stimulation sites – such as with bilateral stimulation. A Series-Y BNC cable is required to operate two PlexBright LED Modules from a single channel.
Optogenetic Commutators	- PlexBright Dual LED Commutator - PlexBright Dual LED + 16 Channel Commutator for simultaneous use with analog headstages, - Carousel Commutator for simultaneous use with digital headstages	All support up to two specially designed, easily interchangeable, Compact LED Modules. Carousel commutators also enable simultaneous neural recording.
Optogenetic LED Module Styles	- Table-top - Compact - Head-Mounted	The Table-top style is generally used for head-fixed or in vitro experiments. The Compact or Head-Mounted style is generally used with a PlexBright commutator.
Optogenetic LED Module wavelengths	Royal (450nm), Blue (465nm),Green (525nm), Lime (550nm), Yellow (590nm), Orange (620nm), Red (630nm), Crimson (660nm), Infrared (740-940nm), Ultraviolet (365-405nm)	The 550nm Lime LED offers attractive power and a broad activation spectrum to those targeting halorhodopsins and archaerhodopsins. The near-infrared LED modules for photothermal inhibition of neural activity and the ultraviolet LED modules for Ca indicator and Light regulated GABAA receptor (LiGABAR).
PlexBright Optical Patch Cable stimulation tip styles	- Bare Fiber, - LC Ferrule, or - FC Ferrule	Bare Fiber tips are most often used for anesthetized, head-fixed or in vitro experiments; LC Ferrule tips are best suited for chronic experiments with mice or small animals; while FC Ferrule tips offer additional strength in chronic experiments for use with rats and stronger animals. Although researchers use both ferrule size tips with rats, it is highly recommended to consider the stronger FC Ferrule tip as well as the stainless steel jacketing.
PlexBright Optical Patch Cable lengths	0.5, 1.0 or 1.5m	Patch cables can be custom made with lengths to the nearest tenth of a meter. Maximum length for High Performance Patch Cables is 2.3m. High Durability Patch Cables can be made in any length to the nearest tenth of a meter.
PlexBright Optical Patch Cable jacketing	- Stainless steel, mono-coil - Stainless steel armored jacketing	An added protection from animals (chewing, etc.), or from researchers (over bending).
PlexBright Fiber Stub Implant lengths	1, 2, 3, 4, 6, 8, 10 or 12mm (available in boxes of 5 with a price break at 25 stubs)	PlexBright Fiber Stub Implants are used with the LC or FC ferrule-tipped PlexBright Optical Patch Cables when working with freely behaving animals that may be disconnected from time-to-time from the optical cable.
PlexBright Fiber Stub Ferrule sizes	- LC Ferrule, or - FC Ferrule	FC Ferrules are slightly larger and offer a bit more strength than LC Ferrules. Additionally, for a proper fit and optimal light transmission, the ferrule on the PlexBright Optical Patch Cable must match the ferrule on the PlexBright Fiber Stub Implant. For example, if the subject is an agitated rat, then the FC Ferrule Fiber Stub Implant is preferred, and then so is an PlexBright Optical Patch Cable with an FC Ferrule tip.

PlexBright Fiber Stub Implant diameters	- 110/125μm optical fiber, or - 200/230μm optical fiber	The first number represents the core fiber diameter, while the second gives the total fiber diameter including the cladding. PlexBright Fiber Stub Implants utilize the same high performance optical fiber that is found in our PlexBright Optical Patch Cables. The smaller diameter fiber may be more appropriate when minimal tissue disturbance is of special concern and/or for small animals such as mice, while the larger fiber may be more advantageous if maximum power delivered to the tissue is especially important.
Accessories	- PlexBright Light Measurement Kit - PlexBright Optical Fiber Cleaning Kit - PlexBright Series-Y BNC Cable	The PlexBright Light Measurement Kit ensures accurate output measurements of the optical fiber throughout the light path (unlikely to be accurately read without this kit and the contained adaptors). The PlexBright Optical Fiber Cleaning Kit maximizes light transmission at fiber connections and extends the life of the fiber connection tips. The PlexBright Series-Y BNC Cable enables the simultaneous operation of two PlexBright LED modules from a single driver/controller output (channel).

PlexBright LED Power Output With Head-Mounted LED Modules

The PlexBright 4 Channel Optogenetic Controller controlled by Radiant Software is one of the cornerstones of the PlexBright Optogenetic Stimulation System (PlexBright System). Radiant offers unsurpassed control of LEDs or lasers over multiple channels.

Through Radiant’s easy-to-use GUI, each 4 Channel Optogenetic Controller starts, drives and stops up to four channels independently from the most basic signals to the generation of sophisticated output patterns. Further, one channel may drive an LED module, while a second channel drives a laser.

Each channel/output may be configured to deliver up to 1100mA of precision-controlled current to one or two PlexBright LED Modules. Alternatively, outputs may be configured to deliver up to a 5V signal, enabling simultaneous control of both LED modules and lasers. The 4 Channel Optogenetic Controller further enables interaction with third party equipment through eight digital inputs and 16 digital outputs.

Radiant v2’s pattern generation functionality allows researchers to quickly define simple to complex output patterns that may be saved and played back repeatedly. Arbitrary stimulation patterns can also be loaded from user defined text files, or the outputs can be controlled directly by the user in manual mode. Patterns can also be generated in an offline mode for use at a later time.

With respect to LEDs – and like the PlexBright LD-1 Single Channel LED Driver – each output of the 4 Channel Optogenetic Controller is capable of controlling one or two LED modules. When two modules share a single output simultaneously (accomplished via a specialized cable that connects the LED Modules in series called a PlexBright Series-Y BNC cable), each module receives the same control signal. This configuration is particularly applicable to bilateral stimulation experiments.

For higher volume research experiments, Radiant enables the integration of up to four PlexBright 4 Channel Optogenetic Controllers simultaneously operated by a single computer – yielding up to 16 channels of independent output.
