Teplov's far-reaching ideas on the physiological mechanisms of human individual-psychological differences are presented; in particular, his use of "involuntary" experimental methods to study nervous-system types and the "combinability" of nervous-system characteristics. (CS)

This article describes chemical reactions of the body to the birth control pill and lists side effects. (PD)

Analogies can be useful in the study of behavior, physiology, and comparative evolution. Dangers in mistaking a homology for an analogy are discussed. (RH)

This article discusses conditioning courses at colleges and the various teaching methods possible. (JA)

Provides up-to-date information on ranking of physiology periodicals based on citation counts. (JB)

This article discusses a study attempting to determine if a biotelemetry system developed for use on chickens could be suitable for monitoring electrocardiograms of humans during exercise. Techniques for its use are reviewed. (JS)

Fifty-six healthy nontrained women aged 18 to 48 were tested for maximal work capacity on a bicycle ergometer. The women were divided into three age groups. A continuous step-increment bicycle ergometer work test was administered with the workload starting at 150 kpm (kilometers per minute) and 50 pedal rpm (revolutions per minute). The workload…

This study describes the effects of several fixatives and buffers on the morphology of mitochondria from resting and exhausted rats. Rats were run to exhaustion and adjacent portions from the left ventricle or from the soleus were treated with the following fixation procedures: (a) glutaraldehyde buffered with cacodylate, S-collidine, or phosphate…

This study investigated the effects of 30 minutes of endurance jogging on pulse rates at rest, during exercise, and at recovery and eight skinfold fat measures in middle-aged women. Subjects were 15 middle-aged women between 30 and 58 years of age who had not been engaged in any exercise program at least for 1 year. Eight sedentary subjects were…

ORGANIZATION AND PHYSICAL APPEARANCE: The document contains a preface, a list of goals, a list of specific block objectives, a bibliography, a course outline for each of the six blocks, and a quinmester posttest. The six blocks are…

In this paper three experimental techniques are described for studying ambiguous characters and for investigating the relationship between physical attributes and functional attributes. (Author)

A discussion of two classes of natural opiate peptides (endorphins and enkephalins) recently found in the brain, and the role they may play in linking emotion and memory. (BB)
