The group of papers on memory reactivation and consolidation during sleep included in this volume represents cutting edge work in both animals and humans. They support that the two types of sleep serve different necessary functions. The role of slow wave sleep (SWS) is reactivation of the hippocampal-neocortical circuits activated during a waking…

Post-retrieval interference with a memory has uncovered a phenomenon known to the field as reconsolidation. In this article, we will review the specific molecular mechanisms that have been implicated in reconsolidation. As a result of numerous studies over the past five years, it can now be said with a fair amount of certainty that reconsolidation…

Objective: To test the hypothesis that young girls and boys with autism exhibit different profiles of neuroanatomical abnormality relative to each other and relative to typically developing children. Method: Structural magnetic resonance imaging was used to measure gray and white matter volumes (whole cerebrum, cerebral lobes, and cerebellum) and…

There are few available resources for learning and teaching about ethical issues in neuroimaging research with children, who constitute a special and vulnerable population. Here, a brief review of ethical issues in developmental research, situated within the emerging field of neuroethics, highlights the increasingly interdisciplinary nature of…

The prevalence and cost of chronic pain is a major physical and mental health care problem in the United States today. As a result, there has been a recent explosion of research on chronic pain, with significant advances in better understanding its etiology, assessment, and treatment. The purpose of the present article is to provide a review of…

College age students are in the midst of important psychosocial and neurobiological changes. The developmental fluidity of this period of life compels caution in diagnosing and treating depressive episodes, especially in discriminating between bipolar and non-bipolar depression. Treating college age students with depression requires adherence to…

In this study we examined prepotent motor inhibition and responsiveness to reward using a variation of the stop signal reaction time (SSRT) task in clinic- and community-recruited children ages 7 to 12 with attention-deficit/hyperactivity disorder-inattentive type (ADHD-I), ADHD-combined type (ADHD-C), and non-ADHD controls. Contrary to…

Personality/behavioral characteristics of empirically derived subgroups of learning disabled (LD) children (8-11 years old) were examined. A modified Halstead-Reitan battery was administered to 56 LD Ss. Their parents completed personality/behavioral measures. Ss' scores on 13 neuropsychological measures were cluster analyzed, and three subgroups…

The study compared the Halstead-Reitan (H-R) neuropsychological test profiles of 25 normal, 47 learning disabled (LD) and 20 brain damaged (BD) young adults. Multivariate analyses indicated that the H-R battery could differentiate these groups beyond chance expectancy and that the neuropsychological deficits in LD performance are intermediate in…

Discussed are the role of the sensory integration specialist in diagnosing and treating various disorders of sensory integration. (DB)

The human brain is lateralized, different functions being housed in each hemisphere. Several assumptions which are mistakenly considered fact by researchers include: (1) the left hemisphere is for rational functions, while the right is for intuitive functions; (2) the hemispheres do not interact as well with each other as they should; (3) the use…

The role of pharmacologic agents in the treatment of learning and behavior disorders in children is discussed with respect to the biological basis of these disorders. Illustrative studies dealing with autonomic reactivity and cortical excitability as reflected in the cortical evoked response are presented. The question of the combined effects of…

The author suggests that most research on the early detection of learning disabilities is characterisized by an ineffective and a theoretical method of selecting and validating tasks. An alternative technique is proposed, based on a neurological theory of cognitive processes, whereby task analysis is a first step, with empirical analyses as…

The author, a neurologist, looks at the nature of reading disabilities. He suggests that many reading disabilities are the result of normal constitutional differences and that the term "minimal brain dysfunction" is rarely appropriate and does not help the remediation process. Noted are various theories which relate neurology and reading ability.…
