Overview
- Definition: Spontaneous Activity Transients (SATs) are characteristic patterns of brain activity seen predominantly on EEG recordings in neonates and young infants.
- These transient waveforms occur spontaneously, independent of external stimulation.
- SATs reflect ongoing developmental and maturational processes in the neonatal and infant brain.
Neurophysiology and Developmental Significance
- SATs represent the brain’s intrinsic mechanisms for neuronal connectivity, synaptogenesis, and functional maturation.
- They are crucial markers of cerebral cortical and subcortical interaction and are indicative of normal neurodevelopment.
- Serve as biomarkers of normal maturation and can aid in identifying developmental abnormalities or neurological impairment early.
