In the context of EEG, electrocerebral inactivity refers to a state where there is an absence of detectable electrical brain activity. The threshold that is commonly recognized for determining electrocerebral inactivity is set at 2.0 microvolts (μV). This means that if the measured electrical activity in the EEG recording is less than or equal to 2.0μV, it indicates that there is either no significant brain activity or that the brain is in a state of inactivity.

This threshold has been established as a standard in the evaluation and interpretation of EEG readings, particularly in contexts such as assessing brain death or significant neurological impairment. It is vital for healthcare practitioners to understand this level, as identifying electrocerebral inactivity can have significant implications for patient management and prognosis.
