EEG is a non-invasive technique that can measure brain activity. The neural activity generates electrical signals that are recorded by EEG electrodes placed on the scalp. When an individual is engaged in performing a cognitive task, brain activity changes and these changes can be recorded on the EEG graph. Therefore, it is a powerful tool for cognitive scientist aiming to better understand the neural correlates associated with different aspects of cognition, which will ultimately help them...

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that has shown initial therapeutic effects in several neurological conditions. The main mechanism underlying these therapeutic effects is the modulation of cortical excitability. Therefore, online monitoring of cortical excitability would help guide stimulation parameters and optimize its therapeutic effects. In the present article we review the use of a novel device that combines simultaneous tDCS and...

The signal pathway is sequential: electrodes detect voltage fluctuations, an amplifier conditions the signals, and a digitizer converts them into a form suitable for transmission. A receiver then collects the transmitted data for synchronized analysis. Keeping these functions distinct helps connect the original neural activity to the recorded digital signal and its behavioral interpretation.
Wireless EEG telemetry is especially valuable when the research question depends on behavior occurring without a physical cable. Removing the tether reduces cable-related restraint and movement artifacts, making it easier to relate changes in brain state to locomotion, sleep, social interaction, or other tasks. The method therefore supports observations under more ecologically relevant conditions.
Synchronization matters because neural recordings and behavioral observations must be aligned in time to interpret brain-state changes during an action or state. In this system, the receiver supports synchronized analysis of transmitted EEG data, allowing investigators to examine when recorded electrical activity changes relative to behaviors such as movement, sleep, or social interaction.
A basic workflow begins by recording voltage fluctuations with electrodes, then passing the signals through an amplifier and digitizer. The processed data are transmitted to a receiver, where they can be synchronized for analysis. In behavioral experiments, this workflow is paired with observation of freely moving subjects so investigators can relate neural activity to ongoing actions or states.
Researchers can apply the approach across several behavioral contexts, including locomotion, sleep, social interaction, and other tasks. Its value is not limited to collecting EEG traces; it enables comparison of brain-state changes across behaviors while the subject moves or interacts more naturally. These recordings can therefore connect electrical activity with behavior in settings less affected by tether-related constraints.
Compared with a physically tethered recording arrangement, Wireless EEG telemetry reduces restraint associated with a cable and can reduce movement artifacts linked to that tether. This distinction is important when the behavior itself is the experimental focus, because the recording setup may otherwise interfere with locomotion, social interaction, or other natural actions. The method is consequently suited to ecologically relevant behavioral studies.
