The Explorer System

Modular Design for Specialized Applications

Choose from a variety of individual components to build a system as unique as your applications.

An Explorer processor and a single Front End are all you need to start recording.

Additional Front Ends can be added to increase the number of recording channels or to acquire different physiological signals.  Connect an I/O module to control or communicate with external devices through analog and/or digital inputs and outputs.

Link two processors together and operate them as a single system for high channel counts (up to 1024) or for applications such as hyperscanning.


Powered by a wall outlet or internal battery. External batteries are available to extend untethered operational time.


Can be controlled by a computer using an ethernet cable or via Wi-Fi to eliminate cables.


Run the system independently of the computer by preprogramming your experimental controls. Front buttons can be programmed to load custom software or provide feedback during operation.

The Processor

One Explorer Line, Unlimited Possibilites

The Summit

With the Summit Explorer processor featuring the same industry-leading core technology, we’ve made it easy to build a system around your specific applications.

The Summit is compatible with all Explorer Front Ends and can record up to 512 channels, making it perfect for invasive and high channel-count applications.


Modular Physiological Amplifiers and Stimulators
for Custom Neuroscience Experiments

The Explorer line offers four distinct families of Front Ends to provide ideal recording and stimulation capabilities for any modality. Designed with optimal technical specifications for each recording modality in mind, the four families are the EEG, the Macro, the Micro2, and the Physio. Mix and match Front Ends on the same processor to increase the number of recording channels and record additional physiological signals.

Designed with EEG specifically in mind, the EEG family of Front End can be used with nearly any non-invasive surface electrode and is ideal for surface recordings that do not require bipolar or true-differential referencing. For stimulation, the EEG+tES Front End can deliver transcranial (tES), transcutaneous nerve (TENS), or spinal stimulation (TSS) through the same surface electrodes used during recording.


Macro and Macro+Stim

The Macro family of Front Ends was designed to easily connect to standard clinical invasive electrodes. Recording specifications are optimized for applications such as high-resolution ECoG or sEEG. The Macro+Stim Front End features a maximum stimulation current that matches common clinical stimulators, while incorporating novel safety features to prevent excessive discharge.


Micro2 and Micro2+Stim

Ideal for high-resolution, invasive recordings, the Micro2 family of Front Ends is optimized for use with high-impedance microelectrodes and can record single-units. Stimulate and record on all 32 channels simultaneously with the Micro2+Stim for unparalleled stimulation capabilities.


Physio and PhysioD

The Physio family of Front Ends was designed specifically for electromyography. Perform shared reference or true-differential recordings with the 32-channel Physio or the 16-channel PhysioD. Both variations feature technical specifications that are ideal for any type of electrophysiology from the body, such as ECG or non-invasive peripheral nerve recordings.

Explorer Analog and Digital I/O Modules

Where Electrophysiology Meets Behavior

Connect to third party research devices with the Explorer I/O modules.

Use any of our three available configurations: the Explorer Analog I/O, the Explorer Digital I/O, and the combined Explorer Analog + Digital I/O, to seamlessly integrate stimulus presentation systems, eye tracking systems, devices for user feedback, force transducers, external stimulators, and more with your Explorer processor. Combine the Analog I/O and the Digital I/O modules for 28 analog inputs and output and 20 digital inputs and outputs. If that’s more than you need, the combined Analog + Digital I/O module provides a condensed version in a single package.

The Analog I/O and Digital I/O modules can be used independently or together. The Analog + Digital I/O module cannot be used with another I/O module.

The Trellis Software Suite

A Proven Data Acquisition Platform

Visualize and sort both surface and cortical signals with a series of simple and intuitive Trellis applications.

Make real-time measurements with the Impedance Analyzer to quickly and accurately check the impedance of your electrodes. Control stimulation on the fly with sub-millisecond precision using the Stimulation Controller. Featuring an integrated Video Monitoring application, Trellis can capture behavioral data with any number of USB cameras while recording electrophysiology data.

Supported for Microsoft Windows (7, 10), Mac OSx (10.7-10.13), and Linux (Ubuntu 18.04), Trellis has minimal operating requirements, enabling you to keep your preferred computer and operating system.

Stream data from your Explorer processor to multiple computers running Trellis EEG Software using Ethernet or Wi-Fi so everyone can keep an eye on the recordings.
