Neuroscientists uncover the key role of dopamine in learning new motor skills

A new interdisciplinary study by researchers from the Ruth and Bruce Rappaport Faculty of Medicine and the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering at the Technion reveals a surprising insight: local release of dopamine—a molecule best known for its role in the brain’s reward system—is a key factor in acquiring new motor skills

The dark side of psychiatry: How it has been used to control societies

In his new book, No More Normal, psychiatrist Alastair Santhouse recalls an experience from the 1980s when he was a university student in the UK helping deliver supplies to “refuseniks”—Soviet citizens who were denied permission to leave the USSR. These people often faced harsh treatment, losing their jobs and becoming targets of harassment. Some were even diagnosed with a psychiatric condition called “sluggish schizophrenia.”

Two heart conditions have a similar cause—study finds key difference

Two common and potentially deadly heart diseases can be caused by mutations in the same gene. Surprisingly, though, these two conditions are each associated with very different clinical symptoms. Using engineered heart tissue, a team of researchers bring a clearer understanding of this phenomenon. The results are published in the Journal of Clinical Investigation.

Is the risk of brain injury from contact sports being overstated by the media?

More and more people are worried about the long-term effects of contact sports on the brain. In football (soccer), studies have found that repeatedly heading the ball can lead to memory problems and an increased risk of serious brain diseases. This has led to rules limiting heading the ball in youth leagues and calls to protect professional players in similar ways.
