A paper from Rhode Island Hospital and Henry Ford Hospital in Detroit examines whether different presentation formats, presenter characteristics, and patient characteristics affect decision-making for patients requiring treatment for asymptomatic carotid stenosis. Based on the study, the researchers concluded that how the treatment options are presented to a patient strongly impacts patients’ decision-making, while the patient’s age, gender, and education level may also influence the decision. The study was recently published in the journal Neurology.

Is there a general motivation center in the depths of the brain?
A French team coordinated by Mathias Pessiglione, Inserm researcher have identified the part of the brain driving motivation during actions that combine physical and mental effort: the ventral striatum. The results of their study were published in PLoS Biology on 21 February 2012.
Cocaine and the teen brain: Study offers insights into addiction
When first exposed to cocaine, the adolescent brain launches a strong defensive reaction designed to minimize the drug’s effects, Yale and other scientists have found. Now two new studies by a Yale team identify key genes that regulate this response and show that interfering with this reaction dramatically increases a mouse’s sensitivity to cocaine.
Being born in another country may protect against stroke for US Hispanics
New research finds foreign-born Hispanics now living in the United States appear to be less likely to have a stroke compared to non-Hispanic white people. The research was released today and will be presented at the American Academy of Neurology’s 64th Annual Meeting in New Orleans April 21 to April 28, 2012. The research is also being simultaneously published in Stroke: Journal of the American Heart Association.
Scientists identify link between size of brain region and conformity
Every generation has its James Dean: the rebel who refuses to follow the path beaten by their peers. Now, a new study in Current Biology has found a link between the amount of grey matter in one specific brain region and an individual’s likelihood of conforming to social pressures.
