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...

The Resting Membrane Potential

2019
Overview The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential. It is generated by differences in permeability of the membrane to various ions and the concentrations of these ions across the membrane. The Inside of a Neuron Is More Negative The membrane potential of a cell can be measured by inserting a microelectrode into a cell and comparing the charge to a reference electrode in the extracellular...

Non-restraining EEG radiotelemetry is a valuable methodological approach to record in vivo long-term electroencephalograms from freely moving rodents. This detailed protocol describes stereotaxic epidural and deep intracerebral electrode placement in different brain regions in order to obtain reliable recordings of CNS rhythmicity and CNS related behavioral stages.
FAQs
Scalp electrodes detect voltage fluctuations associated with synchronized neuronal activity. Researchers examine these signals as oscillations distributed across frequency bands rather than as responses to a particular stimulus. This frequency-based view helps characterize ongoing brain dynamics and provides a way to study neural activity when no specific task is directing cognition or behavior.
Eyes-open and eyes-closed recordings provide different standardized resting conditions for examining spontaneous activity. Comparing these conditions can help researchers determine whether observed oscillatory patterns, connectivity, arousal, or network organization depend on the participant’s visual state. The approach preserves the task-free nature of the recording while adding an important experimental comparison.
Resting-state EEG patterns can provide information about functional connectivity, arousal, and the organization of brain networks. Connectivity describes relationships among activity recorded from different regions, whereas arousal concerns the brain’s general activation state. Together, these measures help researchers examine how neural systems are organized without relying on performance during a specific cognitive task.
The participant should remain awake and should not perform a specific task during the recording. Researchers also establish whether the session uses eyes-open, eyes-closed, or both conditions, then place electrodes on the scalp to detect ongoing voltage fluctuations. Keeping these conditions consistent supports comparisons of spontaneous activity across participants or experimental groups.
Researchers choose this approach when they want to examine ongoing brain activity without introducing an experimental stimulus or requiring a behavioral response. That makes it useful for studying broad properties such as arousal, connectivity, and network organization. It can also support investigations involving participants or questions for which task performance is not the primary focus.
Applications span brain development, cognition, sleep, neurological disorders, and psychiatric disorders. Recordings can reveal patterns of spontaneous activity associated with changing brain function across these contexts. Researchers may also evaluate whether particular activity patterns could serve as biomarkers, meaning measurable indicators of altered brain function, although their interpretation depends on the study context.
