What is neonatal EEG?
Neonatal EEG is a non-invasive technique used to measure electrical activity in the brain of newborns.
How is EEG recorded in neonates?
EEG is recorded using electrodes placed on the scalp or through an EEG cap designed for infants.
What are the main uses of neonatal EEG?
It is primarily used for diagnosing seizures and assessing brain maturity in preterm and term infants.
What advancements have been made in neonatal EEG?
Recent advancements include the use of multi-channel EEG caps and improved understanding of preterm EEG signals.
Why is full-band EEG important?
Full-band EEG captures all frequencies without distortion, allowing for better detection of brain activity.
How do sensory responses differ in preterm infants?
Preterm infants exhibit larger and longer-lasting sensory responses compared to older children.
What is the significance of sensory testing during EEG?
Sensory testing during EEG can provide insights into the neurological health and development of preterm infants.
