The goal of this study is to characterize the potential effect of artifacts originating from physiological noise on statistical analysis of diffusion tensor MRI (DTI) data in a population. DTI derived quantities including mean diffusivity (Trace(D)), fractional anisotropy (FA), and principal eigenvector (ε(1)) are computed in the brain of 40 healthy(More)
Electrolytic lesions of the central nucleus of the amygdala (ACe) have been shown to attenuate the development of hypertension in spontaneously hypertensive rats (SHR). Whether this was due to destruction of local neurons and/or fibers is unknown. In the present study, neuronal perikarya in the ACe of 4-wk-old SHR were selectively destroyed with ibotenic(More)
