## Abstract The effect of social context on experimental foraging in squirrel monkeys (__Saimiri sciureus__) was investigated. The 12 subjects comprised six pairs in which strong social preference and attraction had been demonstrated during observations of a stable group. Individuals were first tra

Abstract
Pregnant squirrel monkeys were exposed to 2450βMHz (CW) microwaves at an equivalent power density of 10 mW/cm^2^ (SAR 3.4 mW/g) for three hours daily in a cavityβcage module. The exposure began when pregnancy was determined by a hormonal method, and continued through the offspring's first 9.5 months. After irradiation, the brains of the offspring were fixed with formaldehyde, and the inferior vermis of each cerebella was removed and processed for histologic observations. Purkinje cell density in the uvula was determined in sagittal serial sections. There was no significant difference between control and experimental animals in the number of Purkinje cells per mm of Purkinje cell line (linear density), as well as in the density of Purkinje cells in the Purkinje cell layer.

Stereological estimates of the numbers of Purkinje cell nucleoli in human cerebellar cortex have been obtained from systematic random samples of tissue by using the fractionator. The estimates are unbiased by fixation, section thickness, or sampling errors and are independent of any assumptions abou
The effects of undernutrition on the developing cerebellum were studied in 30-day-old rats undernourished from birth by restricting access to the lactating mother. These animals showed a significant reduction in cerebellar weight when compared with well-nourished controls. Quantitative studies of th
## Abstract Male rats, undernourished from birth until 30 days by restricting access to the lactating dam, were given __ad libitum__ food supplies until 80 days. Body weight, whole brain weight and cerebellar weight remained significantly lower in these animals than in normally fed controls. Signif
