Optogenetics Biopotential Telemeter
The Kaha Sciences Optogenetics Biopotential telemeter from ADInstruments is the first fully implantable, wireless optogenetic solution to offer both optogenetic stimulation and recording (EEG, ECG, and EMG) within the same device.
The Kaha Sciences Optogenetics Biopotential Telemeter from ADInstruments is the first fully implantable, wireless optogenetic solution to offer both optogenetic stimulation and recording (EEG, ECG, and EMG) within the same device.
Designed for use in rats, the Optogenetics Biopotential Telemeter is an ideal solution for chronic and therapeutic research applications including heart pacing, seizure suppression, and reducing abnormal motor symptoms, without the restrictions of battery power and tethers.
A 35 cm fiber optic allows for direct placement of the stimulating blue light (460nm) at target cells while the biopotential signal measures the potential difference between the pair of 25 cm coiled electrode leads. The telemeter weighs approximately 12g.
Suitable for use in rats >175g
Fully implantable - No tethers
Reusable telemeters encased in durable, biocompatible hard-shell
Simultaneous biopotential recording (e.g. ECG, EEG or EMG) and Blue LED (460nm) light stimulation
Completely software controlled, user-defined stimulation parameters
Powered by the SmartPad using patented wireless inductive technology, supporting continuous recording at high sampling rates (2kHz) for extended periods
Data transmission range up to 5 meters using battery backup
Cohousing feature enables two rats in the same cage or single rat (>350g) implanted with two telemeters for extended signal recording options
Simple and Customizable Telemetry System Setup
Configure a Kaha Sciences Rat telemetry system to meet your exact research needs. A typical telemetry setup requires one telemeter of your choice and one SmartPad per animal. Each laboratory will just require one Configurator in order to configure all your Kaha equipment.
Configure a system to meet your exact needs
An additional advantage of a Kaha Sciences Rat Telemetry System is the cohousing feature:
- Allows two rats (>175g), each implanted with one telemeter, to be housed together in a single cage to reduce stress of single housing and lab space requirements, or
- Two telemeters implanted in one animal (>350g), allowing the measurement of up to four physiological signals (e.g. Optical stimulation + EEG and brain tissue oxygen).
With Cohousing, the system continues to regulate the power supplied to both telemeters seamlessly while collecting continuous data with the expected accuracy and quality. Cohousing still requires one SmartPad per telemeter, as well as a Configurator System for the laboratory.
Existing systems can be upgraded to use the Cohousing feature without the need to purchase additional hardware. Cohousing also requires ConfigSoft software version 3.0 or later.
