The development of a technique for the recording of fetal brain activity has been highly limited by the inaccessibility of the developing human brain in utero. Based on the needs of resolution and a noninvasive nature, only biomagnetic measurements are suitable for the determination of the integrity of the fetal brain on a routine basis. We have built a new biomagnetic measurement device dedica...

Abstract. Fetal magnetic resonance imaging (MRI) is a rapidly growing field of research for its potential to study brain development in utero. However, in contrast to adult studies automatic brain extraction and orientation is not yet solved, but remains challenging in wide field of view raw fetal MRI volumes. This has limited research to small scale studies. This paper presents an automatic fe...

Thyroid hormone is essential for mammalian brain development, but the mechanisms by which thyroid hormone exerts its effects, the developmental processes affected, and the timing of thyroid hormone effects are poorly understood. An important question is whether thyroid hormone of maternal origin is essential in guiding fetal brain development. In both humans and rats, thyroid hormone of materna...

Background: The oxidant-antioxidants balance in the living organism is constantly challenged by internal and external pressures. Maidenhair or Adiantum capillus-veneris (Acv) is rich in bioactive compounds with antioxidant effects.  Objectives: The present study aimed at investigating the effect of Acv hydroalcoholic extract on the oxidative stress rate of blood and brain of mice in the depres...

Introduction Fetal MR brain imaging is proving to be a powerful modality with which to evaluate the developing fetal brain. Advanced imaging strategies, such as diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI) have recently been applied to the human fetus [1,2]. The major difficulty of performing DWI of the fetal brain in utero is the presence of motion, which is especially m...
