Simultaneous recordings of auditory brainstem and middle latency responses were obtained in both vertex-ipsilateral and vertex-contralateral derivations in 22 children, ages 8-12. For specific recording conditions, the latencies of middle latency responses differ significantly between children with and without learning disabilities, offering…

Averaged cortically evoked potentials to frequency-modulated tones were obtained from 12 children with specific language impairment (SLI) and 12 controls. Responses from SLI children were not significantly different from those of normal language learners, indicating no difference between groups with respect to neural systems involved with…

The relationship between mental retardation and brain size is discussed. Research suggests that a common path for many otherwise idiopathic mild retardation cases (genetic or environmental) could be small brain size, indicating reduced information processing capacity. Suggestions are made for further research on neuron number. (SLD)

Fourteen Dutch children with dyslexia were compared with controls on automatic processing under a dual task (motor balance task and auditory choice task) model. Results indicated the dyslexic group was more impaired in the dual task condition than in the single task condition, compared with controls. Findings support the automatization deficit…

Connectionist (parallel distributed processing) modeling provides a new way to approach the neurological study of language. This method focuses on the interplay between a computational model and the appropriate neurological, neuropsychological, and speech and language data, couched in connectionist mechanisms that map naturally to what is known of…

Visual search data are given a unified quantitative explanation by a model of how spatial maps in the parietal cortex and object recognition categories in the inferotemporal cortex deploy attentional resources as they reciprocally interact with visual representations in the prestriate cortex. (Author/SLD)

A review of 11 studies of auditory brainstem response (ABR) in individuals with autism concludes that the ABR data are only suggestive (rather than supportive) of brainstem involvement in autism. The presence of peripheral hearing impairment was observed in some of the autistic individuals. (Author/DB)

Results of applying the electrophysiological measure of auditory long latency event-related potentials (P3 AERP) on 20 children with central auditory processing disorders before and after a structured treatment program found a significant decrease in P3 latency and a significant increase in P3 amplitude when compared with control subjects who had…

A study of 14 nurses who completed a children's neuroscience course found evidence of improved knowledge and increased ability to care for neurology patients. Although the direct impact of continuing education on patient care is difficult to assess, participants' assessment of their learning and its potential to affect patient care is a valid…

Assessment of visual acuity, using Teller Acuity Cards, was combined with observations of behavioral state to indicate central nervous system activation in 24 individuals with mental retardation. Results indicate that forced-choice preferential-looking technique can be used to test visual acuity in this population unless the participant is drowsy.…

Describes empirical research in the fields of neurology and cognitive science that is being conducted to determine how and why the brain learns. Explains ways that video is compatible with how the brain learns and suggests it should be used more extensively by teachers and library media specialists. (LRW)

This article presents a case report of a male child with Fragile X syndrome, typical autistic behavior, and cerebellar hypoplasia. Questions are raised concerning the possible role and importance of cerebellar abnormalities in relation to autistic symptoms. (DB)

Results for sensory thalamocortical latency (3 somatosensory evoked potentials) for 205 college students agree with data that correlate a more extensive visual evoked potential latency with intelligence quotient. Findings suggest that the correlation occurs because the latency indexes cortical nerve conduction velocity. (SLD)

Explains the concept of stretch reflexes to students using a mechanical model. The model provides a dynamic multisensory experience using movement, light, and sound. Describes the construction design. (SAH)

The Self-Memory System (SMS) is a conceptual framework that emphasizes the interconnectedness of self and memory. Within this framework memory is viewed as the data base of the self. The self is conceived as a complex set of active goals and associated self-images, collectively referred to as the "working self." The relationship between the…
