Amuza - Wireless Optogenetics for Freely Moving Animals
- Receivers (head-mounted) are very small and lightweight.
- Used with mice, rats, and marmosets.
- Remote control transmits the stimulation signal to the receiver by infrared.
- Easy scaleup to many animals.
Teleopto’s lightweight receivers and bright LEDs provide up to 13 mW of light to the tip of an attached optic fiber. 1, 2, and 3-gram receivers are available for stimulation of single locations as well as dual (bilateral) locations. We recommend 1 g and 2 g receivers for optogenetic stimulation of mice and 2 grams and larger receivers for optogenetic stimulation of rats and larger animals.
2 channel pulse receivers
The new 2 channel pulse receivers are available in 1 g, 2 g, and 3 g sizes. As with our original pulse receivers, LEDs are ON while the remote is receiving a TTL pulse (or a trigger button is being pressed), and OFF in the absence of a pulse.
2 channel pulse receivers can be used in several different ways:
- With 2 color LED fiber-optics for stimulation and inhibition at a single site
- With bilateral implants, allowing independent control of each side.
- With two single-channel receivers (custom item, please inquire). This allows independent control of the two receivers, mounted at different sites or on different animals.
One limitation of the 2 channel pulse receivers is that only one channel can be activated at a time – both channels cannot be ON simultaneously.
Each unit comprises a three-prong electrical connector, encapsulated LED, and implantable optical fiber. The LED can be blue, green, or yellow.
Single optic fiber: lightweight and robust enough to be inserted without a guide cannula.
LED probe without optic fiber: Flat window for brain surface stimulation.
Two colors LED optic fiber: Two independently controlled LEDs are attached to two 250 μm fibers bundled together.
Bilateral LED optic fiber: for bilateral stimulation.
Two-color Bilateral LED optic fiber: for bilateral stimulation and inhibition.
LED fiber optic Cannula: For stimulation via implantable cannula.
Fiber length, fiber diameter, and the distance between the bilateral fibers can all be made to specification. Please ask about custom LED colors for your wireless optogenetics device.
IR Remote Control
The remote control allows direct control by push buttons for two separate channels. It also allows two-channel control by TTL pulses from programmable stimulators and pulse generators.
Two-Channel Pulse Generator
The STO two-channel pulse generator delivers pulse trains to the Teleopto remote control and also the LAD-1 LED array driver. Pulse trains can be triggered manually or by 5V TTL pulses. TTL pulses can be generated by many types of behavioral test equipment, ask us if you are unsure about compatibility.
TeleHub
The Telehub allows a single remote control to communicate with receivers in up to six operant chambers or other optically isolated environments.
