This video demonstrates a protocol for implanting an electroencephalogram (EEG) and electromyogram (EMG) electrode assembly in an anesthetized mouse. The process involves securing the mouse on a stereotaxic frame, making a midline incision in the skull, drilling holes for the electrodes, and fixing the electrode unit for signal recording. After recovery, the mouse's sleep-wake behavior is analyzed using the recorded signals.

Standard EEG analysis techniques offer limited insight into nervous system function. Deriving statistical models of cortical connectivity offers far greater ability to investigate underlying network dynamics. Improved functional assessment opens new possibilities for diagnosis, prognostication, and outcome prediction in nervous system diseases.

The video demonstrates long-term continuous electroencephalography (EEG) monitoring in rodent pups using a wireless transmitter system. The transmitter contains two recording electrodes and one reference electrode extending to the brain's surface. Upon placing the pup in a recording chamber, EEG can be continuously monitored throughout the pup's development into adulthood.

Mechanisms of sudden unexpected death in epilepsy (SUDEP) are poorly understood and challenging to translate from current models. Transgenic rabbits may offer insights into these mechanisms. We describe a method for long-term, continuous electroencephalography and electrocardiography recordings in transgenic rabbit kits to evaluate serious events that may lead to death.
FAQs
The recorded voltage changes arise when groups of cortical neurons act in a synchronized manner. Greater coordination of this activity creates electrical patterns that scalp electrodes can detect, while less synchronized activity may produce weaker or less distinctive waveforms. This relationship allows clinicians to examine changing neural function rather than relying only on a physical examination.
Continuous recording extends observation beyond the short interval of a routine examination. Because abnormal electrical activity may not occur during a brief assessment, monitoring over time increases the opportunity to identify clinically relevant changes. This is particularly useful when evaluating suspected seizures or epilepsy and when clinicians need information to support treatment decisions.
Amplification makes the detected voltage changes suitable for display, while filtering processes the recorded signals before they appear as waveforms. These steps help present brain electrical activity in a form that can be examined over time. Interpretation of the resulting patterns supports clinical evaluation of neural function and identification of abnormal activity.
A brief examination provides a limited snapshot of a patient’s condition, whereas EEG monitoring follows electrical activity across a recording period. This time-based information can reveal abnormalities that are absent during the examination itself. In clinical medicine, that added temporal perspective is valuable for assessing seizures, altered consciousness, and other neurological conditions.
The process begins with placing electrodes on the scalp to detect voltage changes associated with cortical neuronal activity. The detected signals are then amplified, filtered, and displayed as waveforms. Clinicians interpret these recordings over time, using the observed electrical patterns to evaluate brain function and identify activity relevant to the patient’s condition.
Continuous recording is especially relevant when abnormal activity could be intermittent or when the patient’s neurological state changes over time. Clinical uses described for this approach include seizure and epilepsy evaluation, altered consciousness, sleep-related disorders, and critical care assessment. Longer observation can provide information unavailable from a short examination.
In critical care, ongoing EEG data contribute to assessment of brain function and can help identify abnormal electrical activity over time. The findings may also inform treatment decisions, particularly when a patient’s level of consciousness or neurological status makes direct evaluation difficult. Its value comes from repeated observation of neural activity rather than a single time point.
The same recording approach can be applied to several clinical questions, including suspected seizures, epilepsy, altered consciousness, sleep-related disorders, and broader neurological problems. Its usefulness varies with the question being investigated, but the shared benefit is access to electrical activity over time. This helps clinicians connect observed waveforms with diagnosis, monitoring, and treatment planning.
