Thyroid hormones are important during development of the mammalian brain, acting on
migration and differentiation of neural cells, synaptogenesis, and myelination. The actions of …

A large number of chemical pollutants including phthalates, alkylphenolic compounds,
polychlorinated biphenyls and polychlorinated dibenzodioxins, organochlorine pesticides …

A stereological method for obtaining estimates of the total number of neurons in five major
subdivisions of the rat hippocampus is described. The new method, the optical fractionator …

The present study assessed whether prenatal androgen and estrogen exposure affected
adult spatial learning and hippocampal morphology. Water maze performance, the CA1 and …

For centuries philosophers and scientists have grappled with the existence and meaning of
the differences between the sexes but the idea that there may be differences between the …

Fluid percussion (FP) brain injury causes spatial memory dysfunction in rats regardless of
injury location (midline vs. lateral). Standard histological analysis of the injured brains shows …

Background: Thyroid hormones are important for the adult brain, particularly regions of the
hippocampus including the dentate gyrus and CA1 and CA3 regions. The hippocampus is a …

Fluoro-Jade B (FJB) is an anionic fluorescein derivative that has been reported to
specifically stain degenerating neurons. We were interested in applying FJB staining in a …

Thyroid hormone deficiency has long been considered to affect profoundly such cognitive
functions as learning and memory, which are known to depend on the structural integrity of …

The hippocampal formation presents a special opportunity for realistic neural modeling
since its structure, connectivity, and physiology are better understood than that of other …
