TAINI 20/16

TAINI 20/16, a novel ultra-lightweight (1.8g) low power wireless neural recording system allowing 72-hours of recording from 16 channels sampled at ~19.5 kHz (9.7 kHz bandwidth). It captures local field potentials (LFP) and action-potentials (AP) while animals (e.g mice, rat) engage in unrestricted behaviour in a variety of environments and while performing tasks.

Together with our TAINILIVE software, users are able to view the live recorded signals while configuring the recording settings.

TAINI system can also be synchronized with other external systems, such as video tracking, which allows the recorded data to be synchronized to animals’ behaviour with sub-second precision.
