Running increases neurogenesis in the dentate gyrus of the hippocampus, a brain structure that is important for memory function. Consequently, spatial learning and long-term potentiation (LTP) were tested in groups of mice housed either with a running wheel (runners) or under standard conditions (controls). Mice were injected with bromodeoxyuridine to label dividing cells and trained in the Morris water maze. LTP was studied in the dentate gyrus and area CA1 in hippocampal slices from these mice. Running improved water maze performance, increased bromodeoxyuridine-positive cell numbers, and selectively enhanced dentate gyrus LTP. Our results indicate that physical activity can regulate hippocampal neurogenesis, synaptic plasticity, and learning.

The EU’s Central Asia Strategy approaches its fourth anniversary. In that time the EU has placed its relationship with Central Asia on a more structured footing. Although progress has been made in building dialogue and in furthering engagement, the strategy’s limitations are increasingly obvious. This brief argues that the driving force of the EU engagement should be based on a closer link between security and development. Engagement in this broad field should be underpinned by a values based approach that seeks to promote more explicitly reform on human rights, rule of law, governance and democracy. The momentous changes sweeping across the Middle East and North Africa have demonstrated that even the most apparently durable authoritarian regimes are vulnerable to sudden political shocks.
