Our implantable telemetry devices allow for continuous recording of biopotentials in freely-moving, cohabitating small animals. Researchers across pre-clinical fields employ our system for both short-term and long-term in-vivo studies, and for small scale studies with ten animals to large scale studies with a hundred animals. Visit our Publications and Posters page to read more about how researchers have used our telemetry system.
Epilepsy: Researchers use our transmitters to record EEG in small animals from mice pups to rats. Our event detection program allows for automatic detection of a wide variety of events in local field potentialm(LFP) and electroencephalograph (EEG) recordings.
Optogenetics: Our Implantable Stimulator Transponder allows for wireless optical stimulation of tissue, using either a surface mounting LED for surface stimulation, or a fiber-coupled LED for deep stimulation. We provide free EEG and EMG event detection software that allows for respnse with real-time stimulus.
Spreading Depolarization: Our DC transmitters allow researchers to detect and record spreading depolarization in animal models. All of our transmitters digitize analog inputs with sixteen-bit precision, allowing for monitoring of biopotentials at frequencies down to DC and up to 640 Hz. Operating life ranges from 5-500 days, depending on device configuration
Stroke: Our telemetry devices provide continous, realtime monitoring of the brain, which allows researchers to observe abnormal activity surrounding a stroke, identify charachteristics of idchemic events, and enables long term monitoring of the brains recovery after a stroke.
Sleep: Wireless eeg monitoring aids researchers in their understanding of sleep and its affects on a wide variety of conditions, such as alzheimers, obesity, addiction, and epilepsy.
Telemetry Devices
Transmitters & Stimulators
Subcutaneous Transmitter (SCT): Telemetry devices for implantation in small animals. Many configuration options: mass 1.6 g to 14 g, low-frequency cut-off 0.0 Hz (DC) to 20 Hz, high-frequency cut-off 20 Hz to 640 Hz, input dynamic range 30 mV to 300 mV, 1 to 4 channels, lead thickness 0.5-0.7 mm, lead length 20-260 mm, depth or surface electrodes. Configuration-dependent operating life 5 to 500 days.
Head Mounting Transmitter (HMT): A biopotential sensor that mounts on the head of a small animal by means of a miniature connector, compatible with our subcutaneous transmitter (SCT) system.
Implantable Stimulator-Transponder (IST): An implantable stimulator designed for long-term experiments requiring intermittent, short-duration stimulation. Provides pulsed, variable-current electrical stimulation with a bipolar electrode, or pulsed optical stimulation with one of our implantable lamps.
Implantable Inertial Sensor (IIS): An implantable accelerometer and gyroscope for recording the dynamics of fish swimming or rodents running.
Electrodes, Leads & Accessories
Subcutaneous Depth Electrode (SDE): Accessories for our imlantable sensors and stimulators, permit recording and stimulus in deeper parts of the brain.
Subcutaneous Lead (SCL): The same flexible, silicone-insulated, fatigue-resistant, corrostion-proof leads we use with our implantable telemetry sensors, but sold separately.
Electrode Interface Fixture (EIF): A connector with leads and electrodes designed to be cemented to the head of a small animal and mate with one of our HMTs.
Implantable Light-Emitting Diode (ILED): A variety of implantable lamps for use with our Implantable Stimulator-Transponders (ISTs). We have red, green, and blue Surface-Mount Light-Emitting Diodes, and green and blue Fiber-Coupled Light Emitting Diodes.
Data Acquisition System
Animal Cage Camera (ACC): A wide-angle, wide depth of field camera that provides compressed video synchronous to ±0.1 s with telemetry recordings. Provides night-day programmable, dimming and brightening white and infrared illumination.
Animal Location Tracker (ALT): A combined receiver, activity monitor, and location tracker in the form of a platform we place beneath a cage full of animals with implanted SCTs
Faraday Enclosures (FE): Faraday cages with internal absorbers designed to block and absorb 902-915 MHz microwaves so as to provide a quiet space for micropower telemetry.
