Thu, 29 Sep 2016 New treatment strategy could cut Parkinson's disease off at the pass
Researchers report they have identified a protein that enables a toxic natural aggregate to spread from cell to cell in a mammal's brain -- and a way to block that protein's action. Their study in mice and cultured cells suggests that an immunotherapy already in clinical trials as a cancer therapy should also be tested as a way to slow the progress of Parkinson's disease, the researchers say.
Thu, 29 Sep 2016 Scientists track unexpected mechanisms of memory
Our brains hold on to memories via physical changes in synapses, the tiny connections between neurons. Unexpected molecular mechanisms by which these changes take place have now been revealed by new research.
Thu, 29 Sep 2016 Cocaine accumulation in fish eyes
A study using a new imaging method has revealed that, surprisingly, cocaine accumulates in the eyes of zebrafish. The findings indicate that chemicals – especially psychoactive drugs – need to be assessed quite differently with waterborne exposure than, for example, when pharmaceutical substances are tested in mice. In particular, the uptake mechanisms and effects of cocaine in fish cannot simply be transferred to mammals or humans.
Wed, 28 Sep 2016 How the brain decides between effort and reward
In a new study, researchers investigated what parts of the brain may be involved in deciding if something is worth the effort. The team found a relevant pattern of activity in three areas of the brain, the supplementary motor area (SMA), dorsal anterior cingulate cortex (dACC) and putamen.
Wed, 28 Sep 2016 Brain disruptions similar across many emotional disorders
In an analysis of existing studies that used MRI images to study the brain’s white matter, researchers describe common brain abnormalities found in multiple emotional disorders.
