We have examined the physiological weight changes seen in rat dams and their offspring as sequelae of either an overt or a hidden form of chronic protein malnutrition. In the overt model, which was produced by feeding dams a very low protein diet (6% casein) starting 5 weeks prior to conception and continued through lactation, the females showed significant(More)
Using Rapid Golgi and Nissl techniques, three major cell types: fusiform, multipolar and ovoid-shaped were identified in the nucleus raphe dorsalis of male rats at 30, 90, and 220 days of age. We have described the orientation and dendritic architecture of raphe cells as to type and the relationships of these cells to blood vessels and surrounding(More)
Rats whose mothers were maintained on either a 25% casein diet or an 8% casein diet and who were provided the same diet after weaning were tested on delayed spatial alternation or on one of a series of spatial localization problems using the Morris maze (Morris, 1981). Malnourished rats demonstrated perseverative deficits in the form of strings of(More)
In these studies, power spectral analysis techniques were utilized to quantify the EEG obtained from rats reared on either an 8% or 25% casein diet during various vigilance states at two stages of development: (1) adulthood-90 to 120 days old; and (2) immediately after weaning-22 to 23 days old. It was found that the cortical EEG contained relatively more(More)
We have previously reported that irreversible central and peripheral chemical changes and irreversible changes in spontaneous activity of single neurons in the frontal cortex are seen in adult rats who were born to mothers fed an 8% isocaloric casein diet 5 weeks before mating and during gestation, who were cross-fostered at birth by control (25% casein(More)
