Since its introduction in early 1950s, electroencephalography (EEG) has been widely used in the neonatal intensive care units (NICU) for assessment and monitoring of brain function in preterm and term babies. Most common indications are the diagnosis of epileptic seizures, assessment of brain maturity, and recovery from hypoxic-ischemic events. EEG(More)
OBJECTIVE To document the occurrence of genuine sleep stages in the early preterm babies, and to develop an EEG-based index for following sleep wake cyclicity. METHODS Twelve preterm babies were recruited from a study that assessed ventilator strategies. We used altogether 18 polysomnography recordings that were collected at mean conceptional age of 29.3(More)
The aim of this study was to assess the practicality, reliability and safety of a recently introduced method of skin preparation for EEG recordings. We compared the traditional skin abrasion (SA) method to a method called SurePrep (SP), which creates tiny incisions through the upper epithelial layers. The study comprised three parts. In part 1, forearm(More)
OBJECTIVE To develop new standardized eye tracking based measures and metrics for infants' gaze dynamics in the face-distractor competition paradigm. METHOD Eye tracking data were collected from two samples of healthy 7-month-old (total n = 45), as well as one sample of 5-month-old infants (n = 22) in a paradigm with a picture of a face or a non-face(More)
INTRODUCTION Prenatal antiepileptic drug (AED) exposure is associated with an increased risk of cognitive impairment and autism spectrum disorders detected mainly at the age of two to six years. We examined whether the developmental aberrations associated with prenatal AED exposure could be detected already in infancy and whether effects on visual attention(More)
OBJECTIVE Prenatal exposure to antiepileptic drugs (AEDs) is associated with an increased risk of cognitive dysfunction at early school age. Our aim was to investigate whether signs of adverse drug effects on brain function could be detected already during the first 2 weeks of life. METHODS We studied prospectively 56 full-term newborns with prenatal(More)
