Discusses the process of aging in the brain, including some of the structural and chemical changes that take place in the nerve cells as they age. (CS)

Discusses recent brain research as it pertains to reading instruction. (DD)

Analysis of event-related potentials associated with detected targets in a vigilance task showed that a negative component (N2) covaried in latency with reaction time. These results support the hypothesis that N2 reflects a decision process which controls behavioral responses in sensory discrimination tasks. (BB)

Presents a paper that relates human behaviors, such as pleasure, pain, learning, and speech to specific anatomical areas of the brain. (MLH)

Presents the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research guidelines for performing psychosurgery. Also includes dissenting arguments of commission members favoring a total ban of psychosurgery. (SL)

Reviews what is known about the neurobiology of learning and then considers the future. Augments the neurobiological analysis with a series of implications and reservations about their use and the social factors in their use which may interact with them. (Editor/RK)

The relationship between physiological learning theory and the school-aged child with minimal brain damage is explored. (Author/SBH)

On the basis of a search of the literature and extensive inquiries to clinicians, cases that contained any information concerning possible neuropathologic changes in cases of childhood autism or psychosis were catalogued. (Author/SBH)

Today, researchers can learn about blood flow, electromagnetic fields, and chemical composition of the brain by using functional MRI (magnetic resonance imaging). As biologists, medical researchers, and cognitive scientists learn more about brain functions, educators must keep informed, study, and apply what they have learned in the classroom.…

Syntactic processing was explored in nine individuals who stutter (IWS). Grammaticality judgments and event-related brain potentials (ERPs) were obtained while participants read sentences, half containing verb-agreement violations, via computer or paper. Judgment accuracy of IWS for the online task, but not offline, was lower, especially for more…

Comparison of children (n=6) with either autism or Asperger syndrome (AS) and children (n=9) with neither condition found overall postural instability was significantly reduced in autistic children compared with both AS and normal children and confirms the existence of a visuo-postural detuning in autistic children. Results suggest a…

Tests the hypothesis that, because it uses tri-dimensional sensory pathways which show a higher rate of neural activity than uni- or bi-dimensionals, lab-activity-based instruction is a more effective teaching strategy for learning science than verbal-based instruction. Applies manipulative teaching strategies that use visual, somatosensory, and…

Autopsy analysis of eight dyslexic brains found that the ordinary asymmetry in a language-relevant area of the temporal lobe was missing. The greater development of the right side may reflect an increase in the total number of neurons involved in language processing, resulting in changes in interhemispheric interactions. (JDD)

Auditory brainstem responses (ABR) were measured in 535 children from 3 months to 3 years of age. Results suggested that changes in wave V latency with age are due to central (neural) factors and that age-appropriate norms should be used in evaluations of ABR latencies in children. (Author/DB)

A theory of the development of anomalous dominance and its biological associations is explained and the literature is reviewed in an attempt to apply this theory to the study of autism. The review supported the increased incidence of left-handedness, learning disabilities, and immune disorders postulated by the theory. (Author/DB)
