Scripps Florida scientists devise accelerated method to determine infectious prion strains

... mouse line called Tga20 plays an important role, because it succumbs rapidly to prion disease. "The prions primarily target the brainstem and the thalamus of this transgenic mouse, explaining why these animals have a shorter incubation time than their normal counterparts," Lasmzas said. "The prion ...

Wayne State University and Children's Hospital of Michigan Research Team Discover Chemical That Plays a Major Role in Pediatric Obsessive-Compulsive Disorder

... significant associations between glutamate receptor and transporter genes and abnormal brain volumes in brain regions implicated in OCD such as the thalamus ('grand central station' in the brain), caudate nucleus (brain's secretary), anterior cingulate cortex (brain's arousal center) and orbital ...

Gulf War Syndrome May Stem From Chemical Exposure

... areas we previously suspected responded abnormally to the cholinergic challenge," Haley said. "Those areas were in the basal ganglia, hippocampus, thalamus and the amygdala. "Changes in functioning of these brain structures can certainly cause problems with concentration and memory, body pain, ...
