This review focuses on the postnatal neuroanatomical changes that arise during the first
years of human life. Development is characterized by 2 major organizational periods. The …

This quantitative Golgi study extends our investigation of relationships between cortical
dendrite systems in humans and higher cognitive functions. Here we examine the …

Effects of motor training on a neocortical nerve cell population involved in performance of
the motor task were assessed by measuring Layer V pyramidal neuron apical dendritic …

Background and Purpose—d-Amphetamine administration increases behavioral recovery
after various cortical lesions including cortical ablations, contusions, and focal ischemia in …

In organs other than the brain, cell activation seems to increase “wear and tear,” eg, by
increased free-radical formation, and so to cause an increased rate of aging. However …

Ovariectomized adult female canaries were treated with physiological doses of testosterone,
dihydrotestosterone, or estradiol. Singing, which is typical of males, occurred in the …

Male and female hooded rats were raised from weaning in either a complex or an isolated
environment in two separate replications. After one month, the brains were Golgi-Cox …

Evidence for structural modifications in the brain following environmental changes have
been provided during the last decades. The most pronounced alterations following …

Animals placed in complex environments develop greater numbers of visual cortex
synapses per neuron than animals housed in standard cages. Increased numbers of …

The idea that sleep might be involved in brain plasticity has been investigated for many
years through a large number of animal and human studies, but evidence remains …
