In A Nutshell Researchers used focused sound waves to temporarily quiet the amygdala in healthy adults, reaching a deep brain structure without surgery. When the amygdala was dampened, participants ...

It can take seconds for us to develop a new fear and years for us to forget it. Scientists from the Netherlands are trying to find new ways to quickly unlearn our fears.

Findings reveal sound waves can modulate fear learning and memory, enabling faster unlearning of fear, and advancing noninvasive brain therapies.

Astrocytes, once thought to be mere brain “support cells,” are now revealed to be key players in fear memory. Researchers found they actively help form, recall, and weaken fear responses by ...

In a study published in Neuron, Ciaran Murphy-Royal, researcher at the Center de recherche du Center hospitalier de l'Université de Montréal (CRCHUM), and his team show that astrocyte activity in the ...

The Synaptic Physiology laboratory, led by Juan Lerma at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and Miguel Hernández University (UMH) of ...

A new study shows how a dopamine circuit between two brain regions enables mice to extinguish fear after a peril has passed. Dangers come but dangers also go and when they do, the brain has an ...

In a study released on Nov. 20, 2013, researchers at Stanford University School of Medicine have found that measuring the size and connectivity of the amygdala—a part of the brain associated with ...

The social part of the brain is in constant contact with the emotional center of the brain, according to scientists at Northwestern University. The new findings confirm what many have long thought: ...
