Human Brains Develop Wiring Slowly, Differing from Chimpanzees

Research comparing brain development in humans and our closest nonhuman primate relatives, chimpanzees, reveals the speed at which myelin in the cerebral cortex grows, shedding light on the evolution of human cognitive development, and the vulnerability of humans to psychiatric disorders. Myelin is the fatty insulation surrounding axon connections of the brain.

Recent research by Chet Sherwood, associate professor of anthropology in Columbian College of Arts and Sciences, along with Daniel Miller, a former GW graduate student, and other colleagues, reveals this key difference in brain development between human and chimpanzee. The findings were recently published in the September 24th edition Proceedings of the National Academy of Sciences (PNAS).

In the article, Dr. Sherwood and co-authors write that the development of myelin from birth to adulthood in humans is protracted in comparison to chimpanzees. In humans, myelin develops slowly during childhood, followed by a delayed period of maturity beyond adolescence and into early adulthood. In contrast, in chimpanzees, the development of myelin already starts at a relatively more mature level at birth and ceases development long before puberty.

“These observations indicate that a marked delay in the development schedule of the human neocortex may play an important role in the growth of connections that contribute to our species-specific cognitive abilities,” wrote Dr. Sherwood and co-authors.

The developmental timing of myelination is important because it establishes connectivity among parts of the growing brain, which is essential to higher-order cognitive functions, such as decision-making and emotional regulation. These cognitive functions are known to mature relatively late in humans, after the time of adolescence. Also, this period of persistent myelin development during early adulthood in humans is a time of particular vulnerability to neuropsychiatric diseases, including schizophrenia, bipolar disorder, and depression.

TW: animal cruelty,You tube sensation: SLOW LORIS animal cruelty


We have probably all seen this adorable video of the slow loris being tickled or even this one of a slow loris holding a tiny umbrella, but these seemingly innocent videos are actually the result of incredible amounts of animal cruelty.

The Slow Loris is a nocturnal primate from Southeast Asia but thanks to the millions of hits on youtube, slow lorises have become a “must have pet” and are being plucked from their natural habitat and sold for upto £3,500 ($5,500US)Now you would be lucky to see a slow loris in the wild, these beautiful creatures are endangered. 
If this wasn’t bad enough, what these people do to these animals before they are “pet-ready” is so much worse.

slow lorises have a toxic bite, and because of this before they are sold they have their teeth ripped out with pilars or nail clippers so that they don’t cause damage to their “owners”.

This horrible process often causes infection and slow and painful deaths to the lorises.

They are also NOCTURNAL animals, which is why in the videos they are not just being “cute” these animals are disoriented and BLINDED by the bright light.
These harmless little animals suffer terrible stress from exposure to the sunlight at these markets where they are dumped in cramped cages. These timid creatures normally move about quietly in the darkness of the night. 
‘The markets, where they are surrounded by other animals and people, are a nightmare for them. Tragically, many of them die from trauma even before they have been sold.

although there is a global high protection order under the endangered species conventions, that doesn’t stop them being adbucted and sold on the black market.
Few to no lorises can be found in the wild today, suggesting that the illegal trade may be the cause of the population decline. They are now feared to be on the verge of extinction, which is very serious
all because people want to keep these guys as pets. 

When will people learn to just leave animals in the wild, why is there such an obsession with “owning” exotic pets. Your greed and selfishness has put so many animals on the verge of inexistance. You have no right to steal someone from their home and MUTILATE their body, cause them stress and even death all because you want a cute little pet.

see these articles for more information:
Do popular viral videos depict animal abuse 
Killer Cuteness 

please share this post, it might not be too late for these little guys.
also sign this petition to get the videos removed from youtube 

ugh dammit

people who have an obsession with owning exotic animals should probably not be around animals, ever.

ok, this is pretty cute.

Japanese Deer ‘Eavesdrop’ On Monkeys For Food


Sika deer “eavesdrop” on monkey chatter in order to find food, say scientists.

A team from Kyoto University, Japan, tested how macaque monkey calls affected the feeding behaviour of the deer that live on Yakushima Island.

Previous research has focussed on species “listening to” one another to avoid danger.

But when scientists played macaque calls from hidden speakers, the deer gathered nearby, indicating that they associate the sounds with benefits.

Dr Hiroki Koda who led the study said it was a good example of “possible interspecies communication” and that the deer seemed to be eavesdropping as a “foraging strategy”.

Yakushima Island lies to the south of Kyushu, Japan, and is protected by its Unesco world heritage status.

The island, which includes the ancient and famous Yakusugi Forest, is home to 1,900 species and subspecies of fauna. The deer and macaques that live there feed on the fruit of camphor trees.

Researchers first reported the deer “gleaning” fruit from beneath trees where monkeys were feeding in 2004.

Dr Koda from the Primate Research Institute at Kyoto University wanted to investigate how the deer were able to follow the monkeys to foraging sites.

After hiding speakers in the forest he played recordings of calls commonly made between the monkeys during feeding sessions.

In his experiments, Dr Koda found that groups of deer often gathered near speakers during the playbacks, but they rarely gathered during “silent” periods when no calls were played.

Dr Koda now aims to investigate whether the deer can differentiate between the various food calls made by the monkeys.

He explained that there were “many common food items” that both deer and macaques ate.

“But of course,” he said, “some food items are used only by macaques, or only by sika deer.

“When macaques make food-associated calls [for] “macaque fruits”, sika deer might not [respond].”

cheeky deers :D

New monkey species identified in Democratic Republic of Congo

Guardian:A new species of monkey has been identified in Africa in what is only the second time such a discovery has been made on the continent in 28 years. The finding is considered significant because the identification of mammals new to science is rare.

‘Lesula,’ as the monkey is known locally, has a naked face and mane of long blond hairs. Researchers say it is a shy and quiet creature that lives on the ground and in trees in a habitat of lowland rainforests.The animal’s diet consists of mostly fruit and vegetation.

ETA: A more fitting heading: Monkey species in the Democratic Republic of Congo identified by Western scientists as researchers, however, the locals probably already knew most of the information released in the report from the ‘new’ discovery.

Or something like that.
