Maturation of action monitoring from adolescence to adulthood: an ERP studyAlexandra M Hogan
Developmental Cognitive Neuroscience Unit, Institute of Child Health, University College London, UK
Dev Sci 8:525-34. 2005..In conclusion, the neural systems underlying action-monitoring continue to mature throughout the second decade of life, and are associated with increased efficiency for fast error detection and correction during complex tasks...- Brain response to unexpected novel noises in children with low and high trait anxietyAlexandra M Hogan
University of Southampton, Highfield, UK
J Cogn Neurosci 19:25-31. 2007..There was no effect of anxiety on the later novelty P3. These data suggest a subtle moderating role of trait anxiety on brain response to novelty, and further research with clinically anxious children is indicated... - Impact of frontal white matter lesions on performance monitoring: ERP evidence for cortical disconnectionAlexandra M Hogan
Developmental Cognitive Neuroscience Unit, Institute of Child Health, University College London, Great Ormond Street Hospital for Children NHS Trust, London, UK
Brain 129:2177-88. 2006.... - Physiological correlates of intellectual function in children with sickle cell disease: hypoxaemia, hyperaemia and brain infarctionAlexandra M Hogan
Developmental Cognitive Neuroscience Unit, Institute of Child Health, University College London, UK
Dev Sci 9:379-87. 2006..This supports the hypothesis that lowered intellectual function is partly explained by chronic hypoxia, and has wider implications for our understanding of SCD pathophysiology... - An exploratory study of physiological correlates of neurodevelopmental delay in infants with sickle cell anaemiaAlexandra M Hogan
Institute of Child Health, University College London, London, UK
Br J Haematol 132:99-107. 2006..This exploratory study suggests that SCA infants may be at greater risk of neurodevelopmental delay than previously considered, and may provide the impetus for further research into the very early precursors of cognitive impairment... - Intellectual decline in children with moyamoya and sickle cell anaemiaA M Hogan
Developmental Cognitive Neuroscience Unit, Institute of Child Health, University College London and Great Ormond Street Hospital for Children, London, UK
Dev Med Child Neurol 47:824-9. 2005..While the reduction in IQ attributed to SCA does not appear to become more marked with increasing age, the difference between those with and without MMS is associated with increasing effect over time... 
Neurophysiological evidence for cognitive and brain functional adaptation in adolescents living at high altitudeCassandra Richardson
School of Psychology, University of Southampton, UK
Clin Neurophysiol 122:1726-34. 2011..Neurophysiological methods were used to study the effects of high altitude living on brain functions in a subgroup of participants of the Bolivian Children Living at Altitude (BoCLA) project...- Development of aptitude at altitudeAlexandra M Hogan
UCL Institute of Child Health, London, UK
Dev Sci 13:533-44. 2010..Thus, psychomotor slowing is proposed to be an adaptive rather than a deficient trait, perhaps enabling accuracy of mental activity in hypoxic conditions... - Effects of aging on habituation to novelty: an ERP studyCassandra Richardson
School of Psychology, University of Southampton, UK
Int J Psychophysiol 79:97-105. 2011..We extend current understanding of novelty processing in normal aging by comparing this habituation related-hyperfrontality with intellectual functioning... - Detecting white matter injury in sickle cell disease using voxel-based morphometryTorsten Baldeweg
Developmental Cognitive Neuroscience Unit, Institute of Child Health, University College, London, United Kingdom
Ann Neurol 59:662-72. 2006..This study aimed to detect the presence and extent of white matter abnormalities in individuals with SCD using voxel-based morphometry (VBM)... 
Auto-adjusting positive airway pressure in children with sickle cell anemia: results of a phase I randomized controlled trialMelanie J Marshall
Neurosciences Unit, UCL Institute of Child Health, The Wolfson Centre, London, UK
Haematologica 94:1006-10. 2009..Six weeks of auto-CPAP therapy is feasible and safe in children with SCA, significantly improving sleep-related breathing disorders and at least one aspect of cognition...- To sleep, perchance to enrich learning?Catherine M Hill
Division of Clinical Neurosciences, School of Medicine, University of Southampton, UK
Arch Dis Child 92:637-43. 2007..Sleep is critical for health and is undervalued both in our 24 h society and in paediatric clinical practice. Paediatricians need to understand the neurodevelopmental consequences of poor quality sleep in children... - Increased cerebral blood flow velocity in children with mild sleep-disordered breathing: a possible association with abnormal neuropsychological functionCatherine M Hill
Division of Clinical Neurosciences, University of Southampton, United Kingdom
Pediatrics 118:e1100-8. 2006..We hypothesized that there would be cerebral blood flow velocity differences in sleep-disordered breathing children without sickle cell disease that might contribute to the association with neuropsychological deficits... - Cerebral blood flow velocity and cognition in children before and after adenotonsillectomyAlexandra M Hogan
Developmental Brain Behaviour Unit, Neurosciences Unit, University College London Institute of Child Health, London, England
Pediatrics 122:75-82. 2008..The goal was to determine whether amelioration of sleep-disordered breathing through adenotonsillectomy would reduce middle cerebral artery velocity in parallel with improvements in cognition and behavior...
