Hippocampal neurogenesis in adult primates: a systematic review.

It had long been considered that no new neurons are generated in the primate brain beyond birth, but recent studies have indicated that neurogenesis persists in various locations throughout the lifespan. The dentate gyrus of the hippocampus is of particular interest due to the postulated role played by neurogenesis in memory. However, studies investigating the presence of adult hippocampal neurogenesis (AHN) have reported contradictory findings, and no systematic review of the evidence has been conducted to date.

What impact do self-referral and direct access pathways for patients have on health inequalities?

Background: There is increasing interest in self-referral and direct access as alternatives pathways to care to improve patient access to specialist services. The impact of these pathways on health inequalities is unknown.

Objectives: The purpose of this systematic review is to explore the impact of self-referral and direct access pathways on inequalities in health care use.
