What Your Brain Looks Like When You Solve a Problem
(gizmodo.com)
Researchers have revealed that epiphanies physically reshape brain activity. What’s more, they discovered that people remember epiphanies better than solutions reached through a more methodical approach. These results could have important implications for how instructors approach teaching in classrooms.

Glutamate Unlocks Brain Cell Channels to Enable Thinking and Learning
(neurosciencenews.com)
In an effort to understand how brain cells exchange chemical messages, scientists say they have successfully used a highly specialized microscope to capture more precise details of how one of the most common signaling molecules, glutamate, opens a channel and allows a flood of charged particles to enter.

The mysterious flow of fluid in the brain
(quantamagazine.org)
Encased in the skull, perched atop the spine, the brain has a carefully managed existence. It receives only certain nutrients, filtered through the blood-brain barrier; an elaborate system of protective membranes surrounds it. That privileged space contains a mystery. For more than a century, scientists have wondered: If it’s so hard for anything to get into the brain, how does waste get out?

Optimal brain process requires balance between excitatory and inhibitory neurons
(phys.org)
The brain's ability to process information is known to be supported by intricate connections between different neuron populations. A key objective of neuroscience research has been to delineate the processes via which these connections influence information processing.

Brain function requires a constant supply of glucose. However, the brain has no known energy stores, except for glycogen granules in astrocytes. In the present study, we report that continuous oligodendroglial lipid metabolism provides an energy reserve in white matter tracts.
