We designed a dry-type 16 channel EEG sensor which is non-invasive, deformable, and re-usable. This paper describes the whole process from manufacturing the proposed EEG electrode to signal processing of visual evoked potential (VEP) signals measured on a mouse scalp using a dry non-invasive multi-channel EEG sensor.

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...

FAQs
The measured voltage reflects voltage differences associated with synchronized postsynaptic activity across cortical neuron populations. With several electrodes, researchers can examine whether changes occur across one area or as distributed patterns over the scalp, while retaining precise timing information. This combination helps relate neural activity to sensory processing, cognition, sleep, epilepsy, or behavior without reducing the recording to a single location.
Signal interpretation depends on more than the recorded waveform. Artifacts can introduce activity unrelated to the neural process under study, reference choice affects how voltage differences are represented across channels, and volume conduction can complicate assigning a pattern to a particular brain region. These issues must be considered before treating channel similarities as evidence of distributed neural activity.
Multiple channels capture spatial patterns alongside temporal changes. Comparing channels can reveal distributed oscillations, event-related responses, and connectivity patterns rather than activity at only one recording site. This broader view is useful when a research question concerns how brain regions participate together or how neural activity changes during sensory processing, cognition, sleep, or behavior.
A practical workflow begins by placing multiple electrodes across the scalp and collecting voltage differences from the separate channels during the relevant research condition. Researchers then examine the combined recordings for oscillations, event-related responses, or connectivity patterns. Interpretation also requires checking artifacts and considering the reference and volume-conduction issues that can affect the apparent distribution of activity.
Researchers can examine oscillations, event-related responses, and connectivity between brain regions. These outputs organize the recording around ongoing activity, responses associated with events, or relationships among distributed regions. The most informative outcome depends on the scientific question, including whether the study focuses on sensory processing, cognition, sleep, epilepsy, or neurological disorders.
The technique is useful when researchers need to relate changing brain activity to behavior or to processes such as sensory processing, cognition, and sleep. It also supports studies of epilepsy and neurological disorders, as well as brain-computer interfaces. Its millisecond-scale temporal resolution is particularly valuable for linking neural dynamics with events or behavioral changes over time.
