Neuroimaging perspectives on fetal motor behavior.

Area of Science:

• Developmental neuroscience
• Neuroimaging
• Fetal development

Background:

• Early motor behavior originates from supraspinal centers and reflects neurological integrity.
• Altered motor patterns can precede clinical disease manifestation.
• Ultrasound studies have provided foundational knowledge on fetal motor behavior.

Purpose of the Study:

• To review the state-of-the-art in fetal motor behavior research.
• To propose a reconceptualization of fetal motor behavior using advanced imaging.
• To highlight the role of the intrauterine environment in sensorimotor pathway activation and brain development.

Main Methods:

• Review of findings from human and preclinical models.
• Utilizing cine Magnetic Resonance Imaging (cineMRI) to visualize fetal motor behavior.
• Incorporating insights from multimodal imaging approaches.

Main Results:

• CineMRI is a valuable tool for visualizing fetal motor behavior.
• The intrauterine environment significantly influences sensorimotor pathways and brain development.
• Advanced imaging can reveal early biomarkers for neurodevelopmental disorders.

Conclusions:

• A reconceptualized model of fetal motor behavior is needed.
• Understanding the intrauterine environment is crucial for fetal development.
• Multimodal imaging offers a novel source of in utero biomarkers for predicting neurodevelopmental disorders.
