Failure is frequently the end point of laboratory exercises in physiological psychology that involve stereotaxic surgery by inexperienced students. Lab instructors should caution students to pursue the potential location of misplaced brain lesions using a variety of simple behavioral tests and the Thompson stereotaxic atlas. (Author/RM)

A report on the National Bureau of Standards is presented. It provides national measurement standards for some 40 physical quantities related through the laws of physics to the basic six - length, time, mass, temperature, electric current, and luminous intensity. (DF)

The diffraction bands caused by a thin transparent plate of glass inserted over half the field in a spectrometer are discussed. (TS)

Discusses the theory of the Josephson Effect, the derivation of the Josephson voltage-frequency relation, and methods of measuring the fundamental constatn ratio e/h. Various types of Josephson junctions are described. The impact of the measurement of e/h upin the fundamental constants and quantum electro-dynamics is briefly discussed.…

Describes how industrial arts programs can incorporate space age technology into meaningful and interesting learning experiences for students. (GR)

Investigates spatial orientation of infants, comparing behavior in the laboratory to behavior in the infant's home. Also investigates whether the infant relies on his body as a spatial reference system. (Author/SS)

Presents data on release of renin during direct and indirect stimulation of renal nerves. Conclusions show that renin release is influenced by change in activity of carotid and cardiopulmonary baroreceptor systems, and excitation of discrete areas of brain and hypothalamus by changes in renal sympathetic nerve. (Author/SA)

Presents a laboratory experiment demonstrating the binding of calcium/calmodulin to calmodulin kinase II, which is important in the metabolic and physiological activities of the cell. Uses SDS polyacrylamide gel electrophoresis (PAGE). (YDS)
