Wireless Telemetry Starter-Pack (SPT1) The SPT1 is available to purchase and contains everything you need to get up and running with our telemtry system, excluding your transmitter of choice. All of our telemetry devices are compatible, so the form of transmitters, faraday enclosure, and reciever, can vary. See section, "Starter Packs" for more examples!
SPT1: Starter pack for signal reception, with benchtop enclosure.
SPT2: Starter pack for signal reception and activity monitoring, with benchtop enclosure.
SPT3: Starter pack for signal reception and command transmission, with benchtop enclosure.
SPT4: Starter pack for signal reception in an IVC rack, with canopy enclosure.
Research Applications and Examples:
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 (single animal) to large scale (~150 animal) studies.
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.
