Pay attention: How we focus and concentrate

Scientists at Newcastle University have shed new light on how the brain tunes in to relevant information.

Publishing in Neuron, the team reveal the interplay of brain chemicals which help us pay attention in work funded by the Wellcome Trust and BBSRC.

By changing the way neurons respond to external stimuli we improve our perceptual abilities. While these changes can affect the strength of a neuronal response, they can also affect the fidelity of that response.

Lead author Alex Thiele, Professor of Visual Neuroscience explains: “When you communicate with others, you can make yourself better heard by speaking louder or by speaking more clearly. Neurons appear to do similar things when we’re paying attention. They send their message more intensely to their partners, which compares to speaking louder. But more importantly, they also increase the fidelity of their message, which compares to speaking more clearly.

“Our earlier work has shown that attention is able to affect the intensity of responses – in effect the loudness - by means of the brain chemical acetylcholine. Now we have shown that the fidelity of the response is altered by a different brain chemical system.”

In the paper, the team reveal that the quality of the response is altered by means of glutamate coupling to NMDA receptors (a molecular device that mediates communication between neurons). Carried out in a primate model, these studies for the first time isolate different attention mechanisms at the receptor level.

The research builds on the team’s previous studies and has potentially significant implications not only for our understanding of how our brains work but also give an insight into conditions such as schizophrenia, Alzheimer’s disease and attention deficit disorder, and may aid in the development of treatments for them.

I have to say this is completely legit - someone tried to steal her handbag and she simply went “Fuck this- *suplex*”

someone teach me this pweeze-ooc

Ok Ladies, here’s the info on this move.

We are blessed with a low center of gravity. This means that when we get ahold of someone and tip over backward like that, it’s easy peasy for us to do. Especially on a guy. Think of it like a fulcum and lever: they’re the lever, we’re the fulcrum, and because their center of gravity is up in their chest, instead of in their pelvis, when we get down low and lean back, whupsy there they tip right over.

Now, here’s the real deal on that particular move. Check out how this gif end, with the guy’s head on the floor like that? How his torso seems straight up and down, his head and neck on the floor, all his body weight and the momentum of having been tossed over her shoulder?

Yeah, he’s pretty messed up from that. In the really real world, if you do that move correctly, toss your whole body into it, seriously oomph it up and give that mugger a throw, you can snap his neck.

All that said, here’s how you do it!

This is something you do fast, ladies. Move quickly and with assurance, and don’t worry about whether you’re strong enough to do it or not: you are. This is about physics, not muscle.

Get low, bend your knees and hips. Our strength is largly concentrated in our lower bodies, and when we put our knees and thighs into a move, we bring some of the largest muscles in the human body to bear. You’d be surprised what you can move with your legs.

When she got low on him, her right arm was around his waist, her shoulder roughly at or under his ass, her left arm wrapped around his left leg. Feet shoulder width apart for a nice stable base, big deep breath in, and lift just a bit while falling backwards. It doesn’t take much strength but it will really mess with the dude’s day. Landing on your head will at the very very least knock you silly for a minute.

Interestingly, we can use these same basic principles to ruin a guy’s day if he’s the one to grab us! Imagine, if you will, mugger dude runs up behind you and bear hugs you in preparation for dragging you into the alley. Scary, right? Yep.

If he lifts you too fast, and you find your feet off the ground, kick him in the shins, scrape your shoes down his legs, aim for the knees and his feet. Toss your head back and head butt him. Bite him. Squirm. Do what it takes to get your feet back on the ground.

Feet on the ground, grab his arms and hold on to them. Don’t let him get away, because this move, ladies, will put him down and out, and if he moves away he may go for a distance weapon, or start using his fists. Hold onto his arms and keep him in close.

Again, feet shoulder width apart. Use your booty and hips now, like you’re trying to hit his not-so-manly bits with your ass, get your hips back, bend your knees and flex your hips. If he’s shortish, you should at this point have picked him up and be balancing him on your back. If he’s tall, you’re now in position to put a crimp in his style in a big way.

Tuck your head to your chest and roll forward, just like you did when you were a kid. Flip yourself forward and let gravity do the rest. You will have your head tucked down, aiming to land on the upper back of one shoulder; he won’t. This means he’ll land on his face, with the full force of his own body weight behind it as well as any momentum you’ve built up. You may very well land on top of him too.

From here, get up, run like hell towards a light source while yelling “help, fire, call 911 (or whatever emergency services number exists in your country)”

Remember, ladies, with just a little understanding of comparative anatomy and physics, you too can put a man on the ground and seriously mess up his day. But then, that’s what he was planning to do to you, so fair’s fair.

Reblogging again because of Gryphyn’s awesome comment. C:

THIS IS AWESOME.

thank

Casual save for reference. 

u go girl

i’m really sick of the phrase “find yourself”

you don’t find yourself 

you make yourself

you’re a blank canvas

don’t waste your time looking for blank canvases

when you’ve had a paint brush in your hand the whole time

you can be anything you want to be 

you don’t need to find yourself 

you already have yourself

now paint

This makes me really sad.

aw :(

Ive reblogged this so many times.

you can actually feel the pain and loneliness in your heart.

he’s not even surprised because this is normal for him :/

It’s a fucking cartoon

It’s a claymation movie actually but that’s beside the point.

The point of movies is (often) to portray real life situations. Who cares if it’s a “cartoon”? There’s someone somewhere that sees this as reality.
