...rognosis." The researchers used 'diffusion tensor' magnetic resonance imaging (MRI), which depicts the diffusion, or displacement, of water molecules through tissue. Ischemia results in tissue changes that are visible with diffusion tensor imaging at least two to three hours before they can be seen on convent...Avoiding punishment is its own reward
...d activity. Kim et al. argue that these functional magnetic resonance imaging (fMRI) results provide direct evidence that avoiding bad outcomes and receiving a reward provoke a similar response in the medial OFC. Avoiding negative outcomes and receiving rewards amount to the same thing for the brain: achie...Carnegie Mellon researchers discover key deficiencies in brains of people with autism
...IQs. In one study, the researchers used functional magnetic resonance imaging (fMRI) to view which parts of the brain were activated in people with autism compared to a control group of normal participants while completing the Tower of London task. In a Tower of London task, participants must -- in a set numb...Yale biomedical engineers receive prestigious Early Career Awards
...usly detect cells that cause autoimmune disease by magnetic resonance imaging, and deliver drugs to those cells," said Fahmy. "The approach is driven by an expert understanding of the basic and clinical science coupled to a promising novel nanotechnology that is rapidly translatable to the clinical setting. ...Study confirms males/females use different parts of brain in language & visuospatial tasks

...he amygdala. Paradoxically, past research using magnetic resonance imaging with children has shown that the amygdala in young males with autism is abnormally large in volume due to precocious maturation. "It is somewhat surprising, therefore, that there are ultimately fewer neurons in the autistic amygdala...Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...rkeley used a combination of microscopic beads and magnetic tweezers to observe that when a DNA molecule is stretched, it actually begins to overwind. This overwinding continues until the force being applied to stretch the DNA exceeds about 30 picoNewtons.

Together, the images provide a highly detailed picture of how the cone snail toxin fits into the binding protein, and thus how it also would fit into a nicotinic receptor. "By p...Researchers discover brain abnormality in kids with autism
...All of the children were age two to four. Using magnetic resonance imaging scans (MRI), the researchers measured the transverse relaxation (T2) of cortical gray and white matter in the children's brains. T2 relaxation is a measure of how tightly bound, or mobile, water is in brain tissue and has been used ...News tips from the Journal of Neuroscience
