The fields of developmental psychology and developmental neuroscience have existed independently of one another for many years. This is unfortunate, as knowledge of how the brain develops can inform the study of behavioral development. In this paper, we provide two examples of how knowledge about brain development has improved our understanding of…

Objectives: The underlying mechanisms of reduced pain perception in anorexia nervosa (AN) are unknown. To gain more insight into the pathology, the authors investigated pain perception, autonomic function, and endocrine parameters before and during successful treatment of adolescent AN patients. Method: Heat pain perception was assessed in 15…

The first case study of identical male twins concordant for DSM-IV Asperger's disorder (ASD) was presented. Their monozygocity was confirmed by short tandem repeat analyses with a probability of 99.999963%. Despite sharing the same DNA and environment, the twins are different in comorbidity (i.e., major depressive disorder in the elder and absence…

The neurophysiological and neuroanatomical foundations of developmental language disorder (DLD) are still a matter of dispute. A main argument is that children with DLD show atypical anatomical asymmetries of speech-relevant brain areas, which possibly affect efficient language processing. In contrast to previous anatomical studies in DLD…

Studies have reported a right visual field (RVF) advantage for coherent motion detection by deaf and hearing signers but not non-signers. Yet two studies [Bosworth R. G., & Dobkins, K. R. (2002). Visual field asymmetries for motion processing in deaf and hearing signers. "Brain and Cognition," 49, 170-181; Samar, V. J., & Parasnis, I. (2005).…

The dynamic and rapidly expanding field of neuroscience traditionally has involved the study of the nervous system from a biological/medical standpoint. In recent years, however, the science has become multidisciplinary, attracting researchers from computer science, psychology, sociology, philosophy, and even the humanities. For public and college…

Behavioral and electrophysiological processing of sequential tones were investigated in reading delayed (RD) and non-reading delayed (NRD) children matched on intelligence and reading level. NRD children performed consistently better on sequencing of tonal patterns. Middle latency event-related potentials from the RD group indicated reduced…

This document presents two articles on the topic of the existence of genetic predisposition for delinquent behavior. In the first article, "The Individual Offender," Richard J. Herrnstein reviews the rich and rapidly growing body of research literature on the relationship between genes and the predisposition for certain social behaviors. He makes…

Neuropsychology combines psychometrics and the study of brain processes. There are two approaches to neuropsychology. The neurologic approach uses brief tests flexibly. The psychometric approach uses standardized graded scales in a set battery. Cortical testing in the form of intellectual abilities testing is 70 years old, yet psychometric…

This experiment investigated the capability for movement and muscle spindle function at successive stages during the development of ischemic nerve block (INB) by pressure cuff. Two male subjects were observed under six randomly ordered conditions. The duration of index finger oscillation to exhaustion, paced at 1.2Hz., was observed on separate…

Described are two different statistical methods (component and discriminant analysis) used to compare electroencephalographic patterns of normal and three types of mentally retarded persons ages 7- to 41-years-old. (CL)

Evidence of a relationship between the electrical responses of the human brain and psychometric measure of intelligence is presented. These involuntary cortical responses, known as average evoked potentials are considered to be the electrical signs of information processing by the brain. The time delays of these responses from presentation of a…

The percentage of rapid eye movement (REM) during sleep is substantially greater in neonates (infants in first month after birth) than in other children or adults. It was hypothesized that REM rate may decline as rates of many response sequences do when repeatedly elicited. Electrical recordings of eye movements were obtained from a 3-day-old male…

Eleven survivors of Reye's syndrome (a form of severe enaphalopathy) ranging in age from 9 months to 12 years were evaluated for neurological and psychoeducational sequelae. (Author)

On January 1, 1977, the Netherlands Institute for Brain Research commenced operations as part of the Royal Netherlands Academy of Arts and Sciences (KNAW). Though some aspects of the research it is undertaking is a new departure, the Institute itself is by no means new. Discusses its early history, recent development, and the content of its…
