Background: Childhood onset schizophrenia (COS) is a rare but severe form of the adult onset disorder. While structural brain imaging studies show robust, widespread, and progressive gray matter loss in COS during adolescence, there have been no longitudinal studies of sufficient duration to examine comparability with the more common adult onset…

Purpose: This study explores the relationship between age and resting-state regional cerebral blood flow (rCBF) in regions associated with higher order language skills using a population of normal children, adolescents, and young adults. Method: rCBF was measured in 33 normal participants between the ages of 7 and 19 years using single photon…

This book describes a neuro-developmental approach to learning difficulty assessment and remediation through assessment of a student's reception of information through the sensory channels, processing of sensory information in the brain, and repertoire of responses for expression. Chapter 1, "Reflexes: Their Impact on Success or Failure in…

The unit provides information on the study of the human brain for students in grades 5-9 with suggestions for extending the lessons for gifted and talented students. Learning activities are offered for ten lessons (sample subtopics in parentheses); introduction to the unit (student pretest and posttest); brain growth; medulla-oblongata-reptilian…

The development of the National Institute of Mental Health and Neuro Sciences (NIMHANS) in Bangalore, India, is chronicled over its 10-year history. The volume begins with an examination of the Institute's organization and administration, funding, staffing, teaching activities, etc. Subsequently, reports from 26 departments of NIMHANS are…

A model was tested in which it was assumed that the left and right cerebral hemispheres have access to independent supplies of resources, which they may use in most kinds of information processing situations. Eight male subjects were specifically selected for having demonstrated a strong right-hand superiority on several manual tasks, and a strong…

This case study reviews the literature related to diet, behavior and learning and describes procedures and results of a change in the diet of an adolescent girl who had an extensive history of problems at home and at school. Studies of nutritional deficiency, nutritional imbalance, allergies, and synthetic food additives are briefly overviewed.…

Research findings in the area of brain growth periodization establish that the human brain does not grow on a constant continuum. Eighty-five to ninety percent of youngsters of average and above ability experience periods of great brain growth between ages 3-10 months, 2-4 years, 6-8 years, 10-12 years, and 14-16+ years. Mental growth data have…

Reported is a research program to observe children at high risk for schizophrenia and explore possibilities of prevention. Characteristics of the high risk group (n=207) observed during 1962 are discussed, and a theory which suggests that schizophrenia is an evasion of life is explained. Among results of a diagnostic assessment conducted 10 years…

Some of the major lines of investigation that point to neurophysiological factors in spatial skill are presented. These lines include: the two hemispheres of the brain, recent studies, tachistoscopic studies, morphological differences between the cerebral hemispheres, Geschwind and Levitsky's discovery, cerebral dominance re-examined, sex…

Investigated was the correlation between socioeconomic status, ethnic group membership, and neurological pathology in a random sample of 508 fourth- and fifth-grade children. (CL)

This study relates excitatory and inhibitory personality variables of a heterogeneous group of severely retarded children to performance on a discrete trial, successive go-no-go intradimensional discrimination learning problem, which was followed by stimulus generalization tests on a color hue continuum and extinction trials.

A study of the functional aspects of Wernicke's and Broca's areas of the cerebral cortex and their relationship to second language learning and ability. Some implications are drawn regarding second language teaching and methodology. There seems to be a relationship between methodology and the neurological mechanism used by students. (AMH)
