Early efforts in physiological research in the United States were produced by lone investigators working in laboratories funded by their own medical practices. In Europe, however, Claude Bernard and Carl Ludwig produced a new model of scientific research laboratories funded by the state that sought to develop the pursuit of biomedical research as…

Outlines methods for manipulating multiple gas data so as to gain the greatest amount of insight into the properties of ventilation-perfusion distributions. Refers to data corresponding to normal and abnormal lungs. Uses a two-dimensional framework with the respiratory gases of oxygen and carbon dioxide. (CS)

It has recently been shown that perceived motion, in the absence of any appropriate retinal motion, is a sufficient stimulus to generate smooth pursuit eye motions. However, three experiments show that perceived motion is not necessary for pursuit, but that retinal motion always governs pursuit. (BB)

The Gordon Research Conferences were established to stimulate research in universities, research foundations, and industrial laboratories. The topics for the conferences are listed as well as the locations and scheduled presentations at each conference. (CS)

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)

Describes experiments demonstrating that root pressure in plants is probably controlled by a circadian rhythm (biological clock). Root pressure phenomenon plays significant part in water transport in contradiction with prevalent belief. (PS)

Tests of the predictivity of the biorhythm theory using 30 staff members of a psychiatry service and 50 patients of a college health center showed low correlations between the observed and predicted feeling states. Most were not statistically significant. (BB)

In eighteen chronic schizophrenics, subcutaneous doses of the dopamine reception agonist, apomorphine, improved psychotic symptoms. The results are interpreted as a consequence of presynaptic dopamine receptor activationby apomorphine with a subsequent decrease in dopamine-mediated neural transmission. (Author/BB)

Discusses the conflicting evidence and points of view presented by scientists involved in research on the nature of memory. The research of one group supports a chemical basis for memory, while the other group presents evidence supporting an electro-physiological basis. (JR)

A new method generates specific predictions concerning the expected frequencies of aphasia after unilateral injury to the brain in the left- and right-handed. These predictions are then compared with the observed data for all known studies between 1935 and 1973 to derive the best-fitting model of hemispheric speech lateralization in the left- and…

Described is the development of bioelectrochemistry and biorheology research. Stressed is the importance of continued development of interdisciplinary research. (SL)

Presents annotated abstracts of 630 papers relating to research in physiology presented in the 1977 meeting of the American Physiological Society. (SL)

Two specialized facilities to produce cells and cell components on a large scale for scientific research have recently been established by the National Science Foundation. (BB)
