Brain structures that show high levels of glucose metabolism also tend to have a high density of GLUT-1 transporters.
Previous studies showed that sustained stimulation of hippocampal mossy fibers (MFs), a brain structure that shows the strongest Zn2+ amount in the brain, produces a great increase in synaptic Zn2+ levels and more recent evidence has demonstrated that such synaptic Zn2+ is a principal factor in modulating neurotransmission.
Due to the fact that a known visual pathway connects the only brain structures that have been shown to be active during magnetic orientation, our findings strongly support the hypothesis that migratory birds perceive the magnetic field as a visual pattern and that they are thus likely to "see" the magnetic field.
Regional volumes, surface area, cortical thickness and curvature are plastic measures of brain structure that commonly show alterations in the presence of aging, learning, and neurodegeneration related to disease.
We performed an immunoelectron microscopy study to determine the subcellular localization of CB2-R in the selected rodent brain structures that we have shown contain CB2-R immunoreactivity [23].
Mr. Gala, who asked that he be identified as openly gay, cited the news release for a 2004 paper in the journal Endocrinology that showed differences in brain structure between homosexual and heterosexual sheep.
Furthermore, the increase in contrast of white matter substructures and deep brain structures show that FLAIR imaging at 7 T may be a valuable addition to MR neuroimaging protocols at this ultra-high field strength.
Miniature brains that show electrical activity akin to "a primitive type of thinking" could revolutionise how some drugs are tested and reduce the need for animals in research, according to scientists who have developed the structures.
In this study, we used voxel-based morphometry to investigate differences in regional gray matter volume (rGMV /regional white matter volume (rWMV) between science and humanities students to test our hypotheses that brain structures previously robustly shown to be altered in autistic subjects are related to differences in faculty membership.
Between these extremes are a number of genes that show variability across the structures of the brain.
