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…

GRADES OR AGES: Twelfth grade. SUBJECT MATTER: The human body processes in normal and in certain abnormal conditions. 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)

The functional architecture of the primary visual cortex has been explored by monitoring the responses of individual brain cells to visual stimuli. A combination of anatomical and physiological techniques reveals groups of functionally related cells, juxtaposed and superimposed, in a sometimes complex, but presumably efficient, structure. (BB)

Describes the rapid advance of molecular genetics over the past 20 years that have accounted for the origin of mutations. This research has revealed that variation within species is much greater than Darwin postulated. (Author/MA)

The author reviews the theoretical base and practical implementation of human development counseling, by which the individual identifies the environmental and physiological conditions that facilitate creativity and learns to manage those conditions to enhance creativity. (CL)
