Medical Center neuroscientists say rest — for more than a day — is
critical for allowing the brain to reset neural networks and repair any
short-term injury. The new study in mice also shows that repeated mild
concussions with only a day to recover between injuries leads to
mounting damage and brain inflammation that remains evident a year after
“It is good news that the brain can recover from a hit if given
enough time to rest and recover. But on the flip side, we find that the
brain does not undertake this rebalancing when impacts come too close
together,” says the study’s lead researcher, Mark P. Burns, PhD,
assistant professor of neuroscience at GUMC and director of the
Laboratory for Brain Injury and Dementia.
This first-of-its-kind study, published in the March 2016 issue of American Journal of Pathology,
modeled repeated mild head trauma as a means to investigate brain
damage that occurs after a sports, military or domestic abuse injury.

Dazzling Images of the Brain Created by
The brain has been called the most complex structure in the
universe, but it may also be the most beautiful.
Greg Dunn earned a PhD in neuroscience before deciding to become a
professional artist. His work captures both the aesthetics and
sophistication of this most enigmatic organ. Here are a few of his
dazzling creations:1-Cortical Columns, 2-Basket and Pyramidals, 3-Gold Cortex
II, 4-Cortical Circuitboard, 5-Brainbow Hippocampus in Blues,
6-Brainbow Hippocampus variations, 7-Glia and Blood Vessels, 8-Glial
Flare, 9-Spinal Cord
“There’s no distinction between painting a landscape of a
forest and a landscape of the brain.”
The patterns of branching neurons he saw through the microscope
reminded him of the aesthetic principles in Asian art, which he had
While much of Dunn’s work focuses on neurons, his subjects also
include other tissue types, such as glia, non-neuronal brain cells
that provide support and protection for neurons.(image 7-8)
One of Dunn’s most arresting pieces isn’t of the brain at all, but
of a slice of the spinal cord.(image 9)
Through his art, Dunn hopes to give voice to scientists whose work
usually isn’t appreciated by the general public, he said. “Art
has the power to capture people’s emotions and inspire in a way that
a lot of charts and graphs don’t have.”
So I read this article and it explained how love works with the brain. It said that the feeling of love is supplied by the most powerful circuits in the brain and that is why it is such a strong emotion. It also has been shown that love at first sight can happen due to dopamine levels reaching the same peak from meeting someone for the first time as a couple who has been in love for a year. To tell apart love and lust, you simply sleep with each other and if after you still want to connect with that person after intercourse then it is love. You can not stop the feeling because it is human natures form of pushing reproduction but you can try to ignore it and lie to yourself which will only lead to increased feelings of depression. Makes sense looking at it this way.
Most animals have smooth brains. The brains of humans (and a handful of animals we consider pretty intelligent – dolphins, chimps, elephants, pigs) start out smooth in the early days of gestation and get more and more wrinkled through infancy.
A wrinkled brain makes sense - folding means you can have a really big cortex but the different parts of the brain won’t be as far apart. But how do brains become wrinkled? Is it programmed somehow - does some genetic code determine the pattern of folds?
A new study from Harvard says no - its just simple physics. They created a 3D model of a smooth fetal brain and coated it with an elastomer gel “cortex.” When they immersed this brain in a special solution, the gel swelled, mimicking brain growth.
Lo and behold, the brain began to buckle, creating folds similar to size, shape and location of a real brain.
Since I get asked a lot about where to learn more about the human brain and behaviour, I’ve made a masterpost of books, websites, videos and online courses to introduce yourself to that piece of matter that sits between your ears.
