Schizophrenia: patients usually have less brain tissue
Major Depression: scans show less brain activity in depressed brain
Alzheimer’s: brain tissue significantly shrinks, hippocampus is usually the first region to go
ADHD: less brain activity in the frontal cortex (area associated with decision making) 
OCD: high brain activity 
Post Traumatic Stress Disorder (PTSD): hippocampal volume reduction (area involved in memory) and increased activation of the amygdala (area involved in emotional responses) 

This is so important! I usually don’t reblog posts but people need to understand that mental illnesses are NO CHOICE! You cannot get over it, or snap with your fingers and just be okay again. It takes constant fixing and a lot of strength to get out of this.So to everyone who judges people with mental disorders: people don’t get a choice to develop a disorder or not, but being stupid and telling them to get over it is a choice.PLEASE DONT JUDGE THINGS UNLESS YOU UNDERSTAND!

Okay, everyone probably knows by now that one of my little pet peeves is badly published ‘science’ without criticism or reflection.
And while yes, mental illness is very, very real I would advise people not to jump on the ‘neuroscience as unquestionable fact’ bandwagon -it’s an incredibly young science with major flaws. And even at that, this post gives you no actual scientific information except for a few impressive looking brain scans.
So here’s a few reasons why you shouldn’t assume that these scans tell us anything about mental illness (as they are presented here).
There is no mention of the method of the tests or even what the hypothesis or theory behind these snippets of research were. Cognitive neuroscience is not about putting a person in the scanner and hitting the on button. It is about studying the brain while it is in action, none of these scans tell you what task elicited these activities, they tell you nothing about the patient’s history aside from a singular diagnoses, they tell you nothing about the controls in place for the study.
The issue about patient history is a big one. The main problem with studying the brains of people diagnosed with schizophrenia is that neuroleptics have a massive effect of the brain, and so any differences in brain function or mass could be caused by the medication. (And it is very, very ethically questionable to refuse to medicate a person with schizophrenia for the sake of research, so I highly doubt that’s the case here.)
Brain volume and activation tells you very little about the mechanism of the disorder, while the disorder is brain based it is widely accepted that disregulation of neurotransmitters is really what is key.
And the big one, the massive one, and the real problem with neuroscience at it’s very heart - THESE TELL YOU NOTHING ABOUT CAUSATION! You cannot say, from these scans, whether a decrease in brain function causes depression, or whether depression causes a decrease in brain function.
Basically, what these scans are showing is what we already know about mental illness just by looking at a persons behaviour. A depressed person has depressed brain activation - who’d have thought it? This is basically a description of what we already know, but this time it’s through ‘scientific scans’ to make the work seem more valid and impressive. When really it’s just too reductionist to be helpful and offers absolutely no new insights into the mechanism of mental illness or any tips into effective treatments.

The Experiments: Seawater

Dr. Hans Eppinger and others at Dachau conducted experiments on how to make seawater drinkable. The doctors forced roughly 90 Gypsies to drink only seawater while also depriving them of food. The Gypsies became so dehydrated that they reportedly licked floors after they had been mopped just to get a drop of fresh water. The experiments caused enormous pain and suffering and resulted in serious bodily injury.

Powerful portraits of the Liberians who beat Ebola

To help humanize the overwhelming statistics, Pulitzer Prize-winning photographer and senior staff photographer at Getty Images, John Moore, visited an Ebola treatment center of the organization, Doctors Without Borders in Paynesville, Liberia. At the treatment center, survivors spoke about the brothers, sisters, husbands and wives they lost due to the disease. They also spoke of recovery, stigmas they continue to face in their villages and renewed hope.

I love telling vegetarians hitler was also a vegetarian.

But he wasn’t.

That was propaganda, made up by Goebbels to give him the aura of a revolutionary ascetic. His chef, Dione Lucas, wrote a book, and in it she wrote: “I do not mean to spoil your appetite for stuffed squab, but you might be interested to know that it was a great favorite with Mr. Hitler, who dined at the hotel often. Let us not hold that against a fine recipe though.” He would often go on semi-vegetarian binges (advised by his doctor), apparently to cure himself of sweatiness and flatulence, but he would still eat meat during these binges.

The word ‘vegetarian’ used to be thrown about quite loosely then also, here’s an article from May 30, 1937, titled ‘At Home With The Fuhrer’: “It is well known that Hitler is a vegetarian and does not drink or smoke. His lunch and dinner consist, therefore, for the most part of soup, eggs, vegetables and mineral water, although he occasionally relishes a slice of ham and relieves the tediousness of his diet with such delicacies as caviar.” Robert Payne, who wrote ‘Hitler: The Life and Death of Adolph Hitler’, said that Hitler’s vegetarianism is “legend”, which was created by Goebbels.

His main diet was extremely meat based, especially with Bavarian sausages, and ham, which all of his biographers claimed. Not to mention, if Hitler was a vegetarian he wouldn’t have banned vegetarian organisations in Germany and the occupied countries, and he also would have urged Germany to have a meat free diet during the WWII food shortage.

elephants are fucking awesome.

I’m glad humans are starting to understand that we’re not the be all and end all of self aware, intelligent animals…

hammer time. schools of scalloped hammerhead sharks photographed in the galapagos by (click pic) alexander safanovmontgomery gilchrist, eric h cheng, norbert wu, franco banfi, todd aki, chris newbert and larry gatz.  

scalloped hammerhead populations have declined by over 95 percent in the past thirty years, largely due to the shark fin trade. this summer, scalloped hammerheads became the first species of shark to be protected by the u.s. endangered species act, one of the world’s strongest wildlife conservation laws.

Like a large number of serial killers Richard Ramirez experienced severe head injuries during his youth. In one instance a dresser collapsed on top of him and he required 30 stitches to fix a laceration that he had sustained to his forehead. In a second instance he was knocked unconscious when he was hit by a swing - this particular head injury caused seizures that persisted throughout his youth. While head injuries do not explain his later crimes, these injuries being a common factor in a significant number of serial killers lives makes it a point of interest.

The skull of a Bengal tiger rests along side the skull of a domestic cat.

Notice the proportionally smaller braincase and eyes in the tiger, and the much larger flanges for muscle attachment, in comparison to the overall size of the skull.

As animals scale up in size, more muscle is needed to bear the additional weight and counteract the effects of gravity. To anchor the increased mass of the muscle, bones become more robust. Thicker, heavier, with larger flanges, and deeper hollows to provide the additional muscle with leverage. 

It’s a cyclic system. More muscle is needed to support heavier bone which in turn supports more muscle…etc. 

You’d think it could go on forever, but as animals become larger and more powerful, they also become heavier. For land predators, the cycle reaches a cutoff size when the increasing weight begins to negatively affect agility, maneuverability, and the ability to successfully catch prey.

Some 900 years ago, a Peruvian healer used a hand drill to make dozens of small holes in a patient’s skull. In her study, Kurin notes trepanations first appeared between 200 and 600 A.D. The medical procedure continued until Spanish conquistadors put an end to the practice in the early 16th century. According to Kurin, these ancient surgeons spent time trying different techniques and experimenting with different ways of opening up the skull.
