Scientific studies have shown that fatty acids and vitamin E can modulate learning and memory processes.

متن کاملJuvenile rats show reduced c-fos activity in neural sites associated with aversion to pups and inhibition of maternal behavior.
Juvenile rats (18-23 days old) interact avidly with pups as novel stimuli and show maternal behavior after only 1-3 days of pup exposure; adults initially avoid pups and require 3-9 days of pup exposure. Upon exposure to pups as novel stimuli, adults had more c-Fos-immunoreactive neurons in the hypothalamus and amygdala--regions associated with aversion to pups--than adults exposed to familiar ...
متن کاملCocaine disrupts pup-induced maternal behavior in juvenile and adult rats.
Impaired onset of maternal behavior in first generation rat dams was previously correlated with rearing by cocaine-treated dams and prenatal cocaine exposure. Pup-induced maternal behavior in non-lactating rats has not been examined with regard to cocaine exposure and rearing conditions. First generation male and female juveniles and young adult males reared by cocaine-treated or control dams a...
متن کاملMaternal separation results in early emergence of adult-like fear and extinction learning in infant rats.
Recent studies in rats have shown that extinction occurring early in life is resistant to relapse and may represent the erasure of fear memories. In the present study we examined the effects of early life stress on extinction in the developing rat, which could have important implications for the treatment of anxiety disorders in those who have experienced early life stress. In the present study...
