In some cases, surgical removal of a small brain region is the best option. However, the region in question varies from one patient to another. This poses neurologists with a dilemma -- exactly which region needs to be removed? In many cases, they select regions of brain tissue that -- in an MRI image, for example -- appear to have an abnormal structure. Mathematicians from the University of Twente, together with researchers from the University Medical Center Utrecht, have used computer simulations to show that it may sometimes be better to remove regions with a normal appearance rather than 'abnormal' brain tissue. Jurgen Hebbink , one of the researchers involved, points out that "Our model yields insight into the key role that the network structure can play. In our simulations it...

A brand new examine from UC Davis working with a mouse mannequin of social nervousness reveals that the "love hormone" oxytocin can improve unfavorable in addition to constructive experiences. After social stress, feminine California mice have extra energetic oxytocin cells within the mind and keep away from novel social conditions.
