Small systems of neurons are discussed as they relate to studies of simple animals and the generating of behavior from interacting systems. (SA)

The chemical dimension of the function of the brain is discussed in this article. The chemical transmitters or substances are related to the excitatory or inhibitory influence on neurons. (Author/SA)

The review examines issues and research relating to the involvement of the central nervous system in reading disorders. Questions regarding subtypes, pre- and perinatal influences, genetics, sex differences, and early identification are briefly surveyed along with a summary of major research findings in neuropsychology and neurology.

"Psychologists in the People's Republic of China are engaged in research concerning theory, Chinese language, child development, vision, audition, and areas of physiological psychology including acupuncture, pain, memory, and central nervous system functioning. The Institute of Psychology within the Chinese Academy of Sciences represents the…

Describes the Extended Attention Span Training (EAST) system for modifying attention deficits, which takes the concept of biofeedback one step further by making a video game more difficult as the player's brain waves indicate that attention is waning. Notes contributions of this technology to neuropsychology and neurology, where the emphasis is on…

This article discusses the contributions of Margaret Byrd Rawson in the field of dyslexia. She was instrumental in the founding of the Jemicy School in Maryland, served as President of the International Dyslexia Association (IDA), and was on the IDA Council of Advisors at the time of her death. (CR)

Described is the discovery that oscillations of electric potential at 40 hertz hold the key to how the brain assembles sense impressions into a single object. Potential implications from this research are discussed. (CW)

The article reviews issues of diagnosis and treatment of children with HIV (Human Immunodeficiency Virus) infection. A spectrum of clinical signs is correlated with serological results. The intense central nervous system involvement typically present in childhood cases is examined. (DB)

Discussed are the neurological aspects of human immunodeficiency virus, its clinical course, prevalence, distribution, risk factors, and outlook for the future. Also discussed are the educational implications of dealing with Acquired Immune Deficiency Syndrome and the possible educational needs should these brain-damaged children be healthy enough…

Describes a demonstration that illustrates the use of behavioral tests of reaction time to infer unobservable physiological mechanisms. Appropriate for use in large introductory psychology classes, students participate in a behavioral experiment that tests a physiological hypothesis. Discusses variations of the experiment and advantages of its…

The study investigated two neurophysiologic components of event-related brain potential during auditory and visual target detection tasks with 11 non-retarded autistic children, 9 retarded autistic children, and 16 normal subjects, aged 15-19. Results were consistent with the hypothesis that non-retarded autism involves abnormal attentional and…

Simultaneous 3- channel recorded auditory brainstem responses (ABR) were obtained from 20 neonates with various high-pass filter settings and low intensity levels. Results support the advocacy of less restrictive high-pass filtering for neonatal and infant ABR screening to air-conducted and bone-conducted clicks. (Author/JDD)

In a study by Toshiaki Hashimoto and colleagues (EC 611 142), 10 infants with developmental delay, poor eye contact, and poor facial expression underwent magnetic resonance brain imaging and were later diagnosed with autism. This offered direct evidence of abnormality of the cerebellar vermis and the brainstem at the beginning stages of behavioral…

This review notes that more behavioral recovery is often seen following damage to the nervous system than should be possible from the limited capability of the nervous system for regeneration and reorganization. The review offers a framework for reconciling the effectiveness of early childhood intervention strategies and the conclusions of…

Explains how a simple three-step algorithm can aid college students in solving synapse transmission problems. Reports that all of the students did not completely understand the algorithm. However, many learn a simple working model of synaptic transmission and understand why an impulse will pass across a synapse quantitatively. Students also see…
