Children raised in the home as English or Welsh monolinguals or English-Welsh bilinguals were tested on untrained word form recognition using both behavioral and neurophysiological procedures. Behavioral measures confirmed the onset of a familiarity effect at 11 months in English but failed to identify it in monolingual Welsh infants between 9 and…

The purpose of this paper is to explore the relationship between constructivism and neural organization. Support is given for a constructivist epistemology in current brain theory. A brief description of constructivism is provided, followed by the implication of this set of beliefs for viewing humans as self-organizing systems. What has been…

Earlier reports of the pain of putting hand and forearm in circulating ice water were recomputed to study how subjects scale that pain and to find appropriate measures of its reduction under hypnotic analgesia. (Editor)

Progress is now being made toward ascertaining the specific effects of rearing conditions on brain and behavior, the properties of the environment that contribute to these effects, and the developmental periods in which brain tissue is most sensitive to environmental modification. (Author/RH)

The desired role of a neurologist on an interdisciplinary team serving mentally handicapped patients is described. (GW)

Text, illustrations, and exercises are utilized in these four learning modules to teach respiratory therapy students a variety of job-related skills. The first module, "Anatomy and Physiology of the Central Controls of Respiration" by Margot Lavich, describes the functions of the five centers of the brain that control respiration and…

The report covers a series of investigations on the effects of biofeedback/muscle relaxation training on the academic achievement of learning disabled (LD) students. In the first study, 32 LD elementary school students made gains in all measures except arithmetic following electromyograph biofeedback/relaxation treatment. Implementation of the…

The purpose of this study was to demonstrate that the neural efficiency of the human brain as measured by parameters of sensory evoked potentials varies depending on the sensory input used within the same subject. The subjects were 213 children aged eight to 16 years, selected randomly. Computer analysis of EEG data was performed in order to…

Electroencephalograms were analyzed during performance of verbal and spatial tasks. Complex scalp distributions of theta-, beta-, and, to a lesser extent, alpha-band spectral intensities discriminated between the two members of a pair of tasks, such as writing sentences and Koh's block design.

A history of what anatomists thought about the brain from the ancient Egyptians and Greeks up to the turn of the present century. (BB)

A brief discussion of neurophysiology, neurotransmitters, and the effect of psychoactive drugs on brain diseases such as schizophrenia. (BB)

Some newly reported research results indicate that slightly abnormal biological rhythms, both long- and short-term, may be key factors in the development of depression and manic-depression. The results may also hold clues about why certain drugs work or fail to work with different individuals. (Author/BB)

Neurometric procedures devised to achieve the goals of neurometrics, detailed in this article are described. The results of research obtained from patients with neurological problems, discusses elderly persons with cognitive empairment, and children with learning disabilities are presented. (BT)

Evidence indicates that local, small brain cells play key roles in information processing in the nervous system. (BT)
