Apollo is an inexpensive, high-performance data acquisition (DAQ) system for in vivo neurophysiology experiments using up to 32 electrodes. Its user-friendly software and plug & play hardware provide researchers with a sophisticated yet easy-to-use neural DAQ system. Its digital signal processor and software acquires, processes, and analyzes physiological signals (e.g., spikes, field potentials) together with experimental events from third-party equipment including behavior, stimulation, and video systems. Stereo audio output allows for real-time monitoring of neural signals using headphones or speakers. A battery-power mode eliminates inadvertent ground loops to ensure high signal-to-noise recordings even in the most demanding EMF noise environments. Apollo is the perfect solution for laboratories new to neurophysiology and experienced researchers not needing many recording channels. Price, portability, and performance also make Apollo the preferred choice for monitoring electrode quality during surgery.

Powerful & Intuitive Software
Apollo's Digital Headstages provide a miniature, featherweight, high-fidelity link to electrodes implanted in in vivo brain preparations for electrophysiology studies.The onboard analog filters and digital circuitry combined with LVDS (low voltage, differential signaling) cable transmission ensure a stable, extremely-high, signal-to-noise link to the brain. The multiplexed output allows just a few wires to carry signals from many electrodes making it ideally suited for recording from freely-behaving animals as small as song birds and baby mice. Expensive and noisy motorized commutators are no longer required. The headstage is compatible with individual microelectrodes, microwire & microelectrode arrays, silicon probes, and ECoG/iEEG grids.
Note: Our headstages are compatible with wireless (untethered) devices from TBSI (a division of Harvard Bioscience) and can be used as plug & play (drop in) replacements for the larger headstages in DAQ systems provided by Open Ephys and Intan Technologies.

Commutators: Electrical, Optical & Fluid Channels
Commutators are critical for minimizing mechanical forces on animals and preventing damage to electrical, optical and fluid channels during freely-behaving animal experiments. We offer a variety of commutators with electrical, optical, and fluid channels. We also build noise-immune interfaces to any in-house built or 3rd-party commutator.
