Recent studies on the biological development of the prefrontal cortex in rhesus monkeys are reviewed. These studies have elucidated the basic neural circuitry underlying the delayed-response function in adult nonhuman primates and suggest that a critical mass of cortical synapses is important for the emergence of this cognitive function.

The first of a series of articles on the human brain focuses on the cyclic nature of brain development. Educational and social issues evolving from current discoveries about the brain are also discussed. (CJ)

The developmental pattern of concurrent synaptogenesis in rhesus monkeys is consistent with a straightforward model of relations between brain and cognitive development. Concurrent synaptogenesis is hypothesized to lay the primary cortical foundation for a series of developmental levels in middle infancy that have been empirically documented in…

Organized in three parts, the nine brief chapters of this report aim to raise the information levels of policy makers and the public concerning several educational issues. After the first chapter's brief introductory indication of the purpose of the publication, chapter 2 provides an overview of changes that have marked the American scene since…

This article provides a literature review on the consequences of adolescent childbearing on postnatal infant development. (DB)

Explores how the body's biological clock affects the way musicians practice and perform. Delineates questions concerning this phenomenon. Discusses the implications for music teaching and focuses on areas for collaborative research between neurology researchers and music educators. (NL)
