Neurophysiology and child development in the US and Sri Lanka (Baby Bravo study)
In this R21 study funded by the NICHD of NIH, we adopt mobile technology so that EEG and evoked potential studies can be done remotely throughout the country of our collaborators in Sri Lanka as well as here in New Mexico. Raw data is sent securely to the Mind Research Network for primary analysis. Clinical assessments are integrated with portable electrophysiology to identify early markers of developmental disabilities in children at risk, and to design new therapy based on the capability of a much more timely diagnosis.
Incidental findings in neuroimaging research.
Neuroimaging provides a tremendous amount of information to the researcher. It also uncovers findings in approximately a third of all research subjects that may not be related to the original research question, but may have medical relevance for the individual. Ethical principles need to be considered when deciding how much and by what method research information is offered directly back to subjects who volunteered for the research project. Our multidisciplinary collaborative group is studying the effect of providing research subjects with an official radiology reading of their MRI scan, probing relationships between key ethical principles such as beneficence, subject autonomy and justice. Our goal is to contribute to the national discussion regarding incidental findings in research, and demonstrate that findings of potential clinical significance can be returned in a way that minimizes harm and maximizes personal benefit for research participants.
Premature Infant Development
Enormous and rapid changes in the brain occur during the neonatal period and first years of our lives, which makes the brain particularly vulnerable to physiologic stresses such as premature birth.
In the project BRain imaging and developmental follow-up of Infants Treated with Erythropoietin (BRITE), led by Drs. Robin Ohls and John Phillips, we are investigating the impact of erythropoietin (Epo) treatment on brain development in young children who were born prematurely (with very low birth weight or VLBW). Our preliminary results on altered neurochemistry in prematurely born children is reported in JP Phillips, et al., Anterior Cingulate and Frontal Lobe White Matter Spectroscopy in Early Childhood of Former Very Low Birth Weight Premature Infants, Pediatr Res. 69(3):224-9 (2011). We observed that both NAA and total creatine are on average low in VLBW children relative to normal birth weight children, suggesting reduced neuronal function or density along with a reduced energy metabolism in VLBW children. These findings were consistent with a lower performance on cognitive tests demonstrated by the VLBW group. Our hypothesis is that follow-up studies on these children 2 years later and after treatment with Epo will reveal a normalization of these biochemical and cognitive markers towards the levels in the healthy control group.

Brain Imaging and Developmental Follow-up of Infants Treated with Erythropoietin (BRITE) Project
This is the first study that uses neuroimaging to study the neurologic consequences of erythropoietin treatment for very premature infants. We follow three groups of children: 1) children born prematurely who were treated in the newborn intensive care unit with erythropoietin, 2) similar premature children who were not treated with erythropoietin, and 3) healthy term-born children. These children are evaluated at approximately 3 years of age and again at approximately 6 years of age with MRI scans and developmental assessments. Our goal is to determine whether early erythropoietin therapy improves developmental outcome, and secondly to characterize the neurologic mechanisms of that improvement.
Comprehensive Evaluation in the Relationships of Early Brain Response Overtime (CEREBRO) Project
This is a longitudinal study of normal brain development from 4 months of age through the preschool years. Children are followed with serial assessments including developmental tests, MRI scans and genetics. Our developmental assessments include a focus on early childhood self-regulation and executive function development. By following this cohort of children over time we hope to characterize individual differences in normal brain development, which offers an opportunity to study brain-behavioral relationships in both healthy children as well as those at risk of developmental disorders.
