A causal mechanism of how novel stimuli promote learning has been identified by brain scientists from KU Leuven and the Flanders Institute for Biotechnology. The findings have implications for improving learning strategies and for the design of machine learning algorithms. “Previous work suggested that novelty might activate the dopamine system in the brain. Therefore we… Read more

The balance between the neurotransmitters serotonin and dopamine may affect whether a person develops social anxiety disorder, researchers at Uppsala University report. Previous research has mainly focused on either the serotonin or the dopamine system individually. “We see that there is a different balance between serotonin and dopamine transport in people with social anxiety disorder… Read more

Sugar influences brain reward circuitry in ways similar to those observed when addictive drugs are consumed, researchers from Aarhus University have found. “There is no doubt that sugar has several physiological effects, and there are many reasons why it is not healthy. But I have been in doubt of the effects sugar has on our… Read more

The area of the brain that produces dopamine, and the brain’s separate biological clock that regulates daily physiological rhythms, are linked, suggests a new study[1]. High-calorie foods disrupt normal feeding schedules, resulting in overconsumption, the work also found. “The diet in the U.S. and other nations has changed dramatically in the last 50 years or… Read more

It’s the latest fad in Silicon Valley. By reducing the brain’s feel-good chemical known as dopamine – cutting back on things like food, sex, alcohol, social media and technology – followers believe that they can “reset” the brain to be more effective and appreciate simple things more easily. Some even go so far as avoiding… Read more
