Epoch Wireless EEG Systems for Animals

Small Animal Wireless EEG System

Two channels of long-term wireless EEG for mice, rats, or pups

Continuous long-term recording

wireless in vivo neural recording
Part #: EPOCH-MSE-SYS, EPOCH-RAT-SYS, EPOCH-PUP-EEG-S
  • Long-term wireless EEG/neural signal system for rats, mice, or pups
  • Dual-channel wireless EEG implantable transmitters
  • Additional transmitters available—just move the receiver tray to record from multiple home cages

Complete system includes a receiver tray, two 2-channel implantable EEG sensor transmitters*, and Faraday cage to collect data from a mouse housed in an industry standard home cage. Each Epoch EEG Transmitter amplifies and transmits two channels of high-fidelity EEG data. To record, simply place the animal’s cage on top of the receiver tray with the implanted animal inside of the cage. EEG data from the sensor is telemetered to the receiving tray and then sent to the data acquisition system.

  • small implants uniquely suited for neonatal and adult rodent recording
    • two-week transmitter suitable for pre-weaned rodents (less than postnatal day 21)
    • two-month transmitter suitable for rats as young as postnatal day 7 and older OR mice as young as postnatal day 12 and older
    • six-month transmitter suitable for adult rats and mice
  • transmitter mounts to the skull with cyanoacrylate
  • reduces surgical time to tens of minutes

When used with an MP Research System, use the power of AcqKnowledge software’s automation and scoring tools to identify seizures, predefine and control recording protocols, or set triggers based on external events (dosing, light changes, etc.).

After recording, use automated EEG analysis routines to quickly score multiple channels of EEG data simultaneously. Derive frequency bands, complete a Frequency analysis, look at Alpha RMS, etc., all with guided automated routines.

No crosstalk

High-quality data—no “crosstalk” between neighboring cages in high-density housing

Compatibility


EPOCH transmitters and BIOPAC DAQ

The receiver tray has BNC connections that easily connect to a BIOPAC data acquisition system or third-party devices capable of accepting signals within the ±5 V range; each channel requires one output cable. Use CBL123 for BIOPAC MP160/HLT or CBL102 for BIOPAC MP150/UIM.

Teflon insulated platinum electrode wires are 10 cm and can be truncated to desired length; custom longer lengths available on request.

This system ships with the default transmitter Gain setting; other Gain settings are available if requested before order is placed. AcqKnowledge software includes the scale settings for each transmitter Gain option.

Neural Implant Gain Options
Typical Use Gain Settings
EEG, ECoG, LFP – default 2000x ±1.0 mV range, 2.0 mVpp in = 4 V out
Status-Epilepticus 800x ±2.5 mV range, 5.0 mVpp in = 4 V out
LFP, EEG in rat or mouse pups 4000x  ±0.5 mV range, 1.0 mVpp in = 4 V out

Additional sensor transmitters can be ordered individually.

Receiver Tray Specifications

Operating Temperature: 30-45ºC
Maximum Tray Dimensions (LxWxH):

Pup (cage attached): 188 mm x 188 mm x 160 mm  (7.4″ x 7.4″ x 6.3″ )
Mouse: 345 mm x 210 mm x 21 mm  ( 13.6″ x 8.25″ x 1″ )
Rat: 429 mm x 216 mm x 21 mm (16.9″ x 8.5″ x 1″)

Maximum Animal Size: 1 Kg
Maximum Output: ±4V

Activate Sensors When You’re Ready to Use Them

Transmitters are shipped deactivated and must be activated within 6 months of shipment to ensure the full active battery-life. Add the Sensor Activation & Test Utility (EPOCH-ACTI) to start the sensor battery when ready to use the transmitter.

  • The reusable activator is battery operated and can be used for any sensors that are ordered as deactivated.
  • Deactivated sensors require that the user has an EPOCH-ACTI on-hand or includes one in the EPOCH order.
  • The activator utility can also output two independent channels of data (sinewaves) for testing purposes.

System Extensions

Add SleepSign for Animals (SSA100W) for complete sleep data analysis.

Use Camera Systems (CAMSYS4 or CAMSYS8) to monitor and record protocols and animal behavior. Recorded video will be time synchronized to the physiological signals in AcqKnowledge for easy investigation of key areas of interest.

Mobita Advances Prestimulus EEG Research

The Mobita 32-Channel EEG recording system was used in research examining if physiological data can be used to predict truly random events that correspond to perceptual stimuli. Baumgart, et al. from the University of California Santa Barbara utilized a quantum random number generator (qRNG) to choose from three randomized conditions: light, sound, and no stimulus. […]
