The hippocampal formation has long been associated with the execution of higher-order cognitive functions, and impairment of this structure following severe stress and aging has been linked to cognitive disturbances. In order to understand the involvement of the hippocampal formation in the mediation of normal and pathological behaviors, much attention has recently been devoted to hippocampal neurogenesis. The dentate gyrus of the hippocampal formation has the ability to generate new neurons throughout the entire life. Surviving de novo produced cells develop into granule neurons and integrate into the functional circuitry. Neurogenesis has been proposed to play a role in hippocampal-mediated learning and has been implicated in the appearance of behavioral pathologies associated with the hippocampal formation.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
