GromPack.
Precision Redefined.
A wireless neurorecording and stimulation device for the Madagascar Hissing Cockroach (MHC). Designed to replace restrictive wired setups, it allows for undisturbed behavioral analysis.
Ultralight Form Factor
The total mass of the headstage is below 6 g, staying well below the biological overload limit of 15 g to minimize the impact on natural behavior.
High-Fidelity Neurorecording
Captures analog neural signals in the 300 to 3000 Hz range with a sampling rate of 12.5 kHz.
Real-Time Preview
Maintains a stable connection within a 10 m open field range, delivering low-latency data preview with sub 100 ms delay.
Integrated Power
Provides an uninterrupted operational time of at least 2 hours of wireless data transfer via an onboard LiPo battery system.
