Tryptophan restriction causes long-term plastic changes in corticofrontal pyramidal neurons.


A Golgi study of third-layer pyramidal neurons from the corticofrontal cortex of tryptophan-restricted rats was carried out. At 40 days of age, dendritic arborization from treated rats was less profuse than that seen in control rats, and enlargement of dendritic processes, as well as an increase of the number of dendritic spines, were observed in 60-day-old… (More)
