News tips from the Journal of Neuroscience

...n vitro . This week, Xie et al. used cell lines to unravel the underlying mechanism. Treatment of naive human H4 neuroglioma cells with 2% isoflurane increased caspase-3 activation and decreased cell viability without affecting secreted A. In APP-overexpressing cells, however, isoflurane increased APP proces...

Impulsiveness linked to activity in brain's reward center

...s. "These data are exciting because they begin to unravel individual differences in brain organization underlying differences in complex psychological constructs, such as 'impulsivity,' which may contribute to the propensity to addiction," says Terry E. Robinson, PhD, of the University of Michigan biopsycho...

Eventually, involution could become a useful surrogate endpoint for research in breast cancer prevention. A possible approach to prevention may be to develop strategies ...

Ludwig Fund donates $20 million to University of Chicago for cancer research

...mistry, imaging and medicine. The goal will be to unravel what makes cancer susceptible to metastasis and what drives the process to completion once it has started. "One reason metastasis is so deadly," Greene said, "is because it is frequently associated with treatment resistance." As an initial focus...
