Stable and plastic unit discharge patterns during behavioral generalization.

A movable microelectrode was implanted in adult cats trained to respond differentially to two different frequencies of light flicker. Unit responses were recorded along cortical and thalamic trajectories. The late components of the poststimulus response of 29% of the cells examined showed statistically significant differences when data from different behavioral outcomes to the same neutral generalization stimulus were compared.

Echocardiographic evaluation of adriamycin cardiotoxicity in children.

Thirty children with malignant solid tumors receiving adriamycin had serial evaluation of left ventricular (LV) function by echocardiography. The echocardiographic studies showed a progressive decrease in myocardial contractility as evidenced by changes in several parameters of LV function with increasing cumulative doses of the drug. Using the patients as their own controls, serial echocardiography appears to be a reliable method for detecting early alteration of cardiac function in the asymptomatic patient. This technique may prove useful to prevent cardiomyopathy secondary to adriamycin and to prolong therapy beyond the currently established limits.
