To evaluate the development of visual cognitive function in childhood, we examined exploratory eye movements in 84 healthy subjects viewing picture-based stimuli. Age-defined groups included 4- to 6-year-olds, 7-year-olds, 10-year-olds, 14-year-olds, 16-year-olds, and adults. In each group, 7 subjects were male and 7 were female. Exploratory eye movements,(More)
To investigate the prefrontal hemodynamic response during a cognitive task in childhood anorexia nervosa (AN), we measured regional cerebral blood volume changes in terms of changes in hemoglobin concentrations [Hb], using near-infrared spectroscopy (NIRS). Sixteen females with AN (mean age 14.2 years old) and 12 age-matched healthy female control subjects(More)
The aim of this research was to compare the Strengths and Difficulties Questionnaire (SDQ) scores and subscale scores in children with high-functioning autism spectrum disorder (HFASD) and attention-deficit/hyperactivity disorder (AD/HD), and also to clarify the differences between parent- and teacher-assessed SDQ scores/subscores in HFASD and AD/HD(More)
The Strengths and Difficulties Questionnaire (SDQ) is a short screening instrument which addresses the positive and negative behavioral attributes of infants, children and adolescents. The SDQ is widely used to evaluate child developmental disabilities, psychological and psychiatric conditions or disorders in Japan. However, we did not have normative data(More)
We present a method to localize intraoperative target vessel bifurcations under bones for ultrasound (US) image-guided catheter interventions. A catheter path is recorded to acquire skeletons for the target vessel bifurcations that cannot be imaged by intraoperative US. The catheter path is combined with the centerlines of the three-dimensional (3D) US(More)
The aim of this study was to investigate the prefrontal activation in childhood anorexia nervosa (AN) patients when imaging symptom-provocative factors such as body type, high-calorie food, and attachment between mother and child. The prefrontal activations during each task, in terms of blood volume changes, were measured by near infrared spectroscopy.(More)
BACKGROUND Cortisol awakening response (CAR) as an indicator of psychological stress and related physical and psychiatric diseases has attracted growing attention from researchers. Although CAR changes have been investigated extensively in children with behavioral and psychiatric disorders, the association between CAR and conventional psychometric scales(More)
We reported the results of the 3-week summer treatment program (STP) for children with attention deficit hyperactivity disorder (ADHD) in 2006. The STP was based on methods established by Professor Pelham in Buffalo, NY and has been used in a number of studies and at a number of sites in the U.S. This is the first STP outside North America. Thirty-six(More)
OBJECTIVE Previous eye-tracking studies using an eye mark recorder have reported that disturbances in exploratory eye movements in adult schizophrenic patients are associated with social functioning. The current study sought to determine whether exploratory eye-movement disturbances are present in children with Asperger's syndrome (AS) compared with(More)
BACKGROUND To improve the accuracy of catheter navigation, it is important to develop a method to predict shifts of carotid artery (CA) bifurcations caused by intraoperative deformation. An important factor affecting the accuracy of electromagnetic maxillofacial catheter navigation systems is CA deformations. We aimed to assess CA deformation in different(More)
