pointing out the obvious

Depression Linked with Hyperconnected Brain Areas

Brain regions may communicate excessively in depression

EEG data reveal how tightly connected the frontal cortex (red) is to the rest of the brain in depression (left) and health (right).

Like an overwhelmed traffic cop, the depressed brain may transmit signals among regions in a dysfunctional way. Recent brain-imaging studies suggest that areas of the brain involved in mood, concentration and conscious thought are hyperconnected, which scientists believe could lead to the problems with focus, anxiety and memory frequently seen in depression.
Using functional MRI and electroencephalography (EEG), psychiatrist Andrew Leuchter of the University of California, Los Angeles, and his colleagues measured the activity of depressed patients' brains at rest. They found that the limbic and cortical areas, which together produce and process our emotions, sent a barrage of neural messages back and forth to one another—much more than in the brains of healthy patients. These signals, Leuchter says, can amplify depressed people's negative thoughts and act like white noise, drowning out the other neural messages telling them to move on.
A separate study by psychiatrist Shuqiao Yao of Central South University in Hunan, China, produced a more nuanced view of these two areas' hyperconnectivity. In work published in Biological Psychiatry in April, Yao and his colleagues reported that stronger links among certain corticolimbic circuits are seen in patients more prone to rumination, the act of continuously replaying negative thoughts. Less connectivity in other corticolimbic circuits corresponded to autobiographical memory impairments, which is another common feature that appears in depression.
Scientists do not know whether these connectivity changes are a cause or an effect of depression. A study earlier this year in Proceedings of the National Academy of Sciences USA, however, found that electroconvulsive therapy—formerly known as shock therapy—both alleviates depression's symptoms and decreases connectivity in the hub where the cortical and limbic systems intersect. These results, says lead author Jennifer S. Perrin, a psychologist at the University of Aberdeen in Scotland, confirm that hyperconnectivity is a hallmark of depression in the brain and should provide a target for new drugs and treatments.

TLDR: Study shows that A factor of depression is the brain over thinking itself and blocking out its ability to see through the dark. 
um ..DUH! I thought this was a given?

I know I have been rather light on the posts as of late.

With this ADD medicine i have been on the creative juices just dont juice the way they used to.
 That and everyday stress between work and looking for a second job to help pay the bills.
Then there is family life, of course.
It is hard to be creative when you have to spend a hour a day* listening to a stupid brain voice telling you how horrible you are. How you have failed in so many ways so many times.

Makes me want to stab my brain with a Qtip just to shut it up.

But never you mind fearless reader, I have some kernels at the bottom of the popcorn bag. Just waiting for them to finish popping.


*half an hour commute to work. each way, each day.

And Lower we go

OK I really dont have much to add to this.
Oh I could rant and rave and marvel at how low humans have stooped to be able to call this crap entertainment but I really think it pretty much speaks for itself.
This show, I think its called Yogi and Boo Boo takes a crap in your brain or something like that, has gotta be on TV not because these people are interesting but just as a way of saying "Sweet Lucifer! Take a look at these fruit bats!"
