Brain development from infancy through childhood involves complex structural and functional changes influenced by both internal and external factors. This review provides a comprehensive analysis of event and task-related brain oscillations, focusing on developmental changes across different frequency bands, including delta, theta, alpha, beta, and gamma. Electroencephalography (EEG) studies highlight that these oscillations serve as functional building blocks for sensory and cognitive processes, with significant variations observed across different developmental stages. Delta oscillations, primarily associated with deep sleep and early cognitive demands, gradually diminish as children age. Theta rhythms, crucial for attention and memory, display a distinct pattern in early childhood, evolving with cognitive maturation. Alpha oscillations, reflecting thalamocortical interactions and cognitive performance, increase in complexity with age. Beta rhythms, linked to active thinking and problem-solving, show developmental differences in motor and cognitive tasks. Gamma oscillations, associated with higher cognitive functions, exhibit notable changes in response to sensory stimuli and cognitive tasks. This review underscores the importance of understanding oscillatory dynamics to elucidate brain development and its implications for sensory and cognitive processing in childhood. The findings provide a foundation for future research on developmental neuroscience and potential clinical applications.

Fabry disease (FD) belongs to the group of lysosomal storage diseases (LSD), which are characterised by insufficient activity of enzymes responsible for the intra-lysosomal breakdown of various substrates. The result is an uncontrolled accumulation of by-products of cellular metabolism. Lysosomal storage diseases are inherited diseases, transmitted mainly in an autosomal recessive fashion.

Article Synopsis
- Lennox-Gastaut syndrome (LGS) and Dravet syndrome (DS) are severe epilepsy types often seen in young children, and a CBD medication (Epidyolex®) has been reimbursed in the Netherlands since December 2022 to help treat their seizures.
- A cost-effectiveness analysis using a Markov model showed that using CBD along with usual care for LGS resulted in additional costs of €28,338 but provided increased quality-adjusted life-years (QALYs) of 1.318, making it cost-effective below the €80,000 threshold.
- For DS patients, CBD plus usual care showed a cost saving of €23,642 while increasing QAL

Functional magnetic resonance imaging (fMRI) studies with adults provide evidence that functional brain networks, including the default mode network and frontoparietal network, underlie executive functioning (EF). However, given the challenges of using fMRI with infants and young children, little work has assessed the developmental trajectories of these networks or their associations with EF at key developmental stages. More recently, functional near-infrared spectroscopy (fNIRS) has emerged as a promising neuroimaging tool which can provide information on cortical functional networks and can be more easily implemented with young children.

Background: Respiratory infections in early life is one identified risk factor for asthma. We hypothesized that infection preventive measures during the COVID-19 pandemic influenced the risk of respiratory morbidity and aeroallergen sensitization in early childhood.
Objective: To compare respiratory morbidity and aeroallergen sensitization in children born before and during the pandemic.

The aim of the current study was to investigate visual scan patterns for the self-face in infants with the ability to recognize themselves with a photograph. 24-month-old infants (N = 32) were presented with faces including the self-face in the upright or inverted orientation. We also measured infants' ability to recognize oneself in a mirror and with a photograph.
