New research conducted by a team led by Dr. PARK Joo Min of the Center for Cognition and Sociality within the Institute for Basic Science (IBS) unveils a novel technique that could transform the treatment landscape for brain disorders.

The team developed a non-invasive brain stimulation method called Patterned Low-Intensity Low-Frequency Ultrasound (LILFUS), which holds tremendous potential for inducing long-lasting changes in brain function.

Scientists have discovered a new neural pathway involved in how the brain encodes the transition to high-intensity fear response behaviors that are necessary for survival, according to a recent study published in Nature.

Jones Parker, Ph.D., assistant professor of Neuroscience, of Pharmacology and of Psychiatry and Behavioral Sciences, was a co-author of the study.

Summary: If neural assemblies between the hippocampus and prefrontal cortex fail to sync together at the correct time, memories are lost.

Learning, remembering something, and recalling memories is supported by multiple separate groups of neurons connected inside and across key regions in the brain. If these neural assemblies fail to sync together at the right time, the memories are lost, a new study led by the universities of Bristol and Heidelberg has found.

Summary: When actors hear their own names during a performance, their response is suppressed by activity in the left anterior prefrontal cortex, a brain area associated with self-awareness.

Actors may suppress their core sense of self when acting, as they immerse themselves in a new role, finds a new study by UCL researchers.

Summary: Rhythmic bursts of activity in the prefrontal cortex reduce variability as an animal focuses on a task.

Working memory, that handy ability to consciously hold and manipulate new information in mind, takes work. In particular, participating neurons in the prefrontal cortex have to work together in synchrony to focus our thoughts, whether we’re remembering a set of directions or tonight’s menu specials.

Summary: Extended intense cognitive work causes potentially toxic byproducts to build up in the prefrontal cortex. This alters control over decision-making, causing a shift toward low-cost actions that require less effort as cognitive fatigue sets in.

It’s no surprise that hard physical labor wears you out, but what about hard mental labor? Sitting around thinking hard for hours makes one feel worn out, too.
