Objectives: Neuroimaging studies have revealed lithium-related increases in the volume of gray matter in the prefrontal cortex (PFC) and hippocampus. Postmortem human studies have reported alterations in neuronal and glial cell density and size in the PFC of lithium-treated subjects. Rodents treated with lithium exhibit cell proliferation in the dentate gyrus (DG) of the hippocampus.

This study compares the cytoarchitectonic parcellation of the prefrontal cortex (PFC) in the mouse as presented in publications that are commonly used for identifying brain areas. Agreement was found to be greater for boundaries in the medial PFC than in the lateral PFC and lowest for those in the orbital areas of the PFC. In this review, we explain and illustrate in a selected series of photographs and stereotactic pictures the differences in location and terminology of the different prefrontal cortical areas.

Currently, well-illustrated mouse brain stereotaxic atlases are available, which, however, do not provide a description of the distinctive cytoarchitectonic characteristics of individual prefrontal areas. Such a description is of importance for stereological, neuronal tracing, and physiological, molecular and neuroimaging studies in which a precise parcellation of the prefrontal cortex (PFC) is required.

In this study, we determined the effect of genotype on the ability to isolate and quantify introduced 2,4-DAPG producers from the rhizosphere of wheat using three different methods: traditional dilution plating on selective media, colony hybridization followed by polymerase chain reaction (PCR), and phlD-specific PCR-based dilution endpoint assay. Regression analysis of the population densities of 10 2,4-DAPG-producing P.
