Now that we know the brain is not completely sequestered from the immune system, new questions arise, Schwartz said. Neurological diseases might be caused by malfunctions in communication between the brain and the immune system, rather than by problems within the brain. According to Rustenhoven, the dural sinuses offer both a location to study diseases like multiple sclerosis or even Alzheimer’s disease and a potential target for treatments.
We can also train our brains to behave in a more ‘aware’ way by engaging in activities that facilitate greater connection or neural synchronisation. Higher synchronisation – imagine a large group of brain cells singing together – has been found following the practice of different contemplative paradigms, such as meditation and prayer (creating, as it were, slower ocean waves, now growing calmer and calmer). One way of interpreting this is that neuronal synchronisation enhances our brain ‘harmony’ or ‘integrity’ – achieving a state in which the brain works in a more congruent way, adopting a more global perspective. Other findings point to the psychological consequences of this state – greater neuronal synchronisation tends to enable a greater ability to make moral judgments and problem-solve creatively.

Research in mice shows that neural representations of sensory information get rotated 90 degrees to transform them into memories. In this orthogonal arrangement, the memories and sensations do not interfere with one another.
The two researchers hypothesized that there might be a psychological explanation: when faced with a problem, people tend to select solutions that involve adding new elements rather than taking existing components away.

These ‘zombie genes’ — those that increased expression after the post-mortem interval — were specific to one type of cell: inflammatory cells called glial cells. The researchers observed that glial cells grow and sprout long arm-like appendages for many hours after death.
“That glial cells enlarge after death isn’t too surprising given that they are inflammatory and their job is to clean things up after brain injuries like oxygen deprivation or stroke,” said Dr. Jeffrey Loeb, the John S. Garvin Professor and head of neurology and rehabilitation at the UIC College of Medicine and corresponding author on the paper.
New research suggests that stimulating neurons in the brain can address psychological issues with surprising speed and precision.

Katy Waldman reviews the new book “Chatter,” by Ethan Kross, an experimental psychologist and the founder of the University of Michigan’s Emotion & Self-Control Lab. The book examines the purposes and pitfalls of the inner voice, as well as how we can marshal it for greater use.
