¹H-MRS was used to study the metabolic changes associated with development of the neural tissue in vivo longitudinally. Different tissues (yolk, eye and vitreous body) of developing chickembryos were scanned at three different stages (E3, E6 and E8) for metabolic quantification. As expected, results indicate that a critical juncture appears between stages E3 and E6 in terms of energetic status of the embryo.
