Summary: Researchers at the Human Brain Project have identified and mapped 7 new areas of the insular cortex.

All newly detected areas are now available as 3D probability maps in the Julich Brain Atlas, and can be openly accessed via the HBP’s EBRAINS infrastructure.
Summary: Dampening retromer activity slows down the trafficking of tau in neurodegenerative disorders, a new study reports.

Neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease are associated with atypical proteins that form tangles in the brain, killing neurons. Neurobiologists at EPFL have now identified some key mechanisms underlying the formation of these tangles.

Summary: Study reveals how the element of surprise helps facilitate learning and memory retrieval.

A study by University of Manchester neuroscientists into the effect of surprise on our memory has inadvertently discovered a method which might help us to perform better in exams.
Summary: Researchers have identified human-specific cell types in the prefrontal cortex. These unique cells may explain why humans are more susceptible to neuropsychiatric diseases than other primate species.

What makes the human brain distinct from that of all other animals—including even our closest primate relatives?
Due to a rare genetic mutation, Aliria Rosa Piedrahita de Villegas should have had Alzheimer’s.
Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.
The flow of time from the past to the future is a central feature of how we experience the world. But precisely how this phenomenon, known as the arrow of time, arises from the microscopic interactions among particles and cells is a mystery—one that researchers at the CUNY Graduate Center Initiative for the Theoretical Sciences (ITS) are helping to unravel with the publication of a new paper in the journal Physical Review Letters. The findings could have important implications in a variety of disciplines, including physics, neuroscience, and biology.
Fundamentally, the arrow of time arises from the second law of thermodynamics: the principle that microscopic arrangements of physical systems tend to increase in randomness, moving from order to disorder. The more disordered a system becomes, the more difficult it is for it to find its way back to an ordered state, and the stronger the arrow of time. In short, the universe’s tendency toward disorder is the fundamental reason why we experience time flowing in one direction.
“The two questions our team had were, if we looked at a particular system, would we be able to quantify the strength of its arrow of time, and would we be able to sort out how it emerges from the micro scale, where cells and neurons interact, to the whole system?” said Christopher Lynn, the paper’s first author and a postdoctoral fellow with the ITS program. “Our findings provide the first step toward understanding how the arrow of time that we experience in daily life emerges from these more microscopic details.”
