The hippocampus, which plays an important role in memory functions and emotional responses, has distinct subregions subserving different functions. Because the volume and shape of the hippocampus are altered in many neuropsychiatric disorders, it is important to understand the trajectory of normal hippocampal development. We present the first dynamic maps(More)
Straub et al. (2002) recently identified the 6p22.3 gene dysbindin (DTNBP1) through positional cloning as a schizophrenia susceptibility gene. We studied a rare cohort of 102 children with onset of psychosis before age 13. Standardized ratings of early development, medication response, neuropsychological and cognitive performance, premorbid dysfunction and(More)
BACKGROUND There are, to date, no pre-post onset longitudinal imaging studies of bipolar disorder at any age. We report the first prospective study of cortical brain development in pediatric bipolar illness for 9 male children, visualized before and after illness onset. METHOD We contrast this pattern with that observed in a matched group of healthy(More)
Prior cross-sectional anatomic brain imaging studies of the hippocampus in schizophrenia have generally shown loss in total hippocampal volume although the progressive course of these changes remains unknown. We report the first prospective sub-regional maps of hippocampal development in childhood onset schizophrenia (COS), reconstructed from serial brain(More)

The convergence of traditional voice-oriented telecommunications networks and data-oriented computer communications networks is yielding new challenges for building systems equally adept at handling voice and data applications. While there is much discussion about packetized voice over IP networks, a little explored opportunity is the ability to more easily(More)
Schizophrenia is increasingly recognized as a neurodevelopmental disorder with altered connectivity among brain networks. In the current study we examined large-scale network interactions in childhood-onset schizophrenia, a severe form of the disease with salient genetic and neurobiological abnormalities. Using a data-driven analysis of resting-state(More)
—This paper presents an experimental study on ultra-sonic focusing in an attenuative solid made of cement mortar. The objective is to comparatively investigate the performance of various techniques for wave focusing. Standard attenuation measurements are performed on small cement mortar samples to generate a preliminary idea about the loss in the material.(More)
