Choose a complete system: amplifier, acquisition station, software and sensor nets. We clarify the contents of each configuration with you.
The GES 500 combines high-density acquisition with Net Station 6 on PC. Desktop and cart configurations are available.
The manufacturer describes a unified interface for EEG and TMS control, with an architecture designed for integrations and closed-loop applications.
Configure my EGI system ↗Availability, options and software features to be specified in your quotation.
The GES 400 combines amplifier, computer, software and nets. Dedicated configurations support TMS or 3 T MRI. We review your existing equipment to identify upgrade options.
Channel count is not everything. Net selection also depends on recording duration, participants and accompanying modalities.
Saline Geodesic Sensor Nets use sponge sensors. The net positions the electrodes together, without scalp abrasion.
An option for sessions requiring quick preparation, particularly with infants and children.
Gel versions are offered for longer recordings, including sleep studies.
We help select sizes, consumables and maintenance conditions for your use.
Geodesic Sensor Nets cover head circumferences from 28 to 64 cm. This range supports research into early development, language, cognition, learning, and perception, from premature infants to adults.
The flexible net positions all sensors together. Magstim EGI brochures highlight quick application and participant comfort. For routine EEG, the clinical flyer cites about 15 minutes after training. Saline nets require no scalp abrasion or glue.
These features can make BabyLab sessions easier to organize. Validate the setup, size, and workflow for each age group, recording duration, and study protocol.
The age ranges below are manufacturer estimates; they vary with sex and growth. Measure head circumference to choose a size, and confirm compatibility with the intended system and configuration.

Discuss a BabyLab configuration ↗From net selection to EEG–TMS integration, explore a few examples of Magstim EGI systems in use.
Net Station supports EEG acquisition, review and processing. The version must match your system: Net Station 6 accompanies GES 500; Net Station 5.5 belongs to the GES 400 range.
MFF data can be used with third-party tools such as EEGLAB and FieldTrip. We check formats and data exchange requirements for your analysis pipeline.
Discuss EGI software with Gaze Intelligence →View the signals and events in your acquisition.
Review software options, for your needs.
Prepare transfers and synchronisation with your environment.
Keep your stimulus presentation tools and link protocol events to EEG data: stimuli, responses and experimental conditions.
The egi-pynetstation library connects a PsychoPy experiment to Net Station, controls recording start and stop, and sends timestamped event markers through the ECI interface.
Visual markers can be tied to the screen refresh; clock-offset and drift correction help maintain their alignment with the EEG.
egi-pynetstation is an independent community open-source project. We help you select the interface and validate your setup.
PsychoPy / Net Station documentation ↗Gaze Intelligence supplies the E-Prime Extensions for Net Station (EENS) add-on to integrate E-Prime with EEG acquisition: recording start and stop, stimulus and response markers, and trial information.
The extension synchronises clocks through NTP/SNTP and sends events over Ethernet using ECI for precise temporal alignment with EEG signals. Its tools integrate directly into E-Studio.
E-Prime / Net Station brochure · PDF ↗Clock synchronisation is complemented by checks of actual stimulus presentation. Photocell or EGI AV Tester tests measure the offset and its variability before data collection. We tailor integration to your PsychoPy, E-Prime and Net Station versions and your amplifier.

Explore the interactive brain →Physio16 is an input box for physiological signals that complement EEG. It records these measurements in synchrony with EEG and displays them together in Net Station.
Each Physio16 provides up to 16 bipolar channels and one SpO₂ channel. Two input boxes can connect to Net Amps 400 for 32 physiological channels and two SpO₂ channels alongside EEG.
The GES 500 offers a new-generation Physio module with 8 to 16 physiological channels plus SpO₂, depending on configuration. This extension combines EEG and physiology, including for sleep research.
We select the module, sensors and connections for your GES 400 or GES 500. Reusing an existing Physio16 with a GES 500 requires a specific compatibility check.
