This publication of the American Physiological Society provides information about some new classroom experiments and techniques. These are: "Negative Feedback Control in the Blowfly--A Laboratory Exercise,""Demonstration of Various Habitats for Investigating Murine Behavior Patterns," and "Use of Behavioral Objectives and Audio-Visual Tutorial…

Thirty-two males were divided into high and low creative groups based on the Remote Associates Test and the Alternative Uses Tests. High creatives exhibited a lower basal alpha index, a higher basal theta index, differential amounts of alpha on creativity and intelligence tests, and were better at alpha control in a feedback situation than low…

A model demonstrating the relationship between the structure of blood vessels and the flow of blood is described and illustrated in the biology section of the newsletter. The apparatus also contains a functional (but not structural) model of the heart. Suggestions for the preparation of a relatively permanent dialysis bag from visking tubing are…

Reported were results of the first year of a 3-year physiological study of the hyperkinetic child. The male subjects were 6 to 9 years of age, attending school, without sensory defects, 80 or above in Wechsler Intelligence Scale for Children Full Scale, off medication for 3 months prior to testing, and diagnosed as hyperactive.…

Describes a physical fitness program for children under age 5 conducted three times a week in a full-size gymnasium converted into a safe place for young normal and handicapped children. (ED)

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.

What shade of gray a surface appears is related to the perceived distribution of light and shadow, which in turn depends on the perceived spatial relation between the surface and its neighbors. (Author/ BB)

Reviews a current book on mathematics for the biologist. Includes a discussion of the general topic and a listing of previous books on mathematics for the life sciences. (MA)

All-pass filter systems can be used in laboratory experiments in the physics and psychophysics of sound and music. Particular applications, such as lateralization of sounds in headphone listening, are presented. (BB)

Mendeleev's prediction of existence of the radioactive element, Polonium, and the discovery of iproniazid and its role in antidepressant therapy are presented. (BB)

Describes a study using heart rate as an index of autonomic arousal to measure the effects on television viewers of depicting the consequences of violence, violence with no consequence, and nonviolence. Supports the conclusion that specific content manipulations of aggressive stimuli affect levels of arousal. (JMF)

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)
