Scambler1 1Developmental Biology of Birth Defects, UCL Institute of Child Health, 2MRC Centre for Regenerative Medicine, SCRM Building, University of Edinburgh We present a protocol for the analysis of coronary vessels in whole embryonic murine hearts up to E15.5, using standard immunological staining methods followed by optical clearance and confocal microscopy. This technique enables visualization of blood vessels throughout the entire heart without the need for time-consuming analysis of serial sections. Developmental Biology Dual Labeling of Neural Crest Cells and Blood Vessels Within Chicken Embryos Using ChickGFP Neural Tube Grafting and Carbocyanine Dye DiI Injection Jean-Marie Delalande1,2, Nikhil Thapar1, Alan J. Burns1,3 1Birth Defects Research Centre, UCL Institute of Child Health, 2Blizard Institute, Centre for Digestive Diseases, Queen Mary University of London, Barts and The London School of Medicine and Dentistry, 3Department of Clinical Genetics, Erasmus University Medical Center, Rotterdam Here we report dual labeling of neural crest cells and blood vessels using chickGFP neural tube intraspecies grafting combined with intra-vascular DiI injection. This experimental technique allows us to simultaneously visualize and study development of the NCC-derived (enteric) nervous system and the vascular system, during organogenesis. Behavior Cortical Source Analysis of High-Density EEG Recordings in Children Joe Bathelt1, Helen O'Reilly2, Michelle de Haan1 1Cognitive Neuroscience & Neuropsychiatry Section, UCL Institute of Child Health, 2Academic Division of Neonatology, Institute for Women's Health, University College London In recent years, there has been increasing interest in estimating the cortical sources of scalp measured electrical activity for cognitive neuroscience experiments. This article describes how high density EEG is acquired and how recordings are processed for cortical source estimation in children from the age of 2 years at the London Baby Lab.
