Humans have developed sophisticated concepts like mass and gravity to explain a wide range of everyday phenomena, but scientists have remarkably little understanding of how such concepts are represented by the brain.
Using advanced neuroimaging techniques, Queen’s University researchers have revealed how the brain stores knowledge about an object’s weight – information critical to our ability to successfully grasp and interact with objects in our environment.
Jason Gallivan, a Banting postdoctoral fellow in the Department of Psychology, and Randy Flanagan, a professor in the Department of Psychology, used functional magnetic resonance imaging (fMRI) to uncover what regions of the human brain represent an object’s weight prior to lifting that object. They found that knowledge of object weight is stored in ventral visual cortex, a brain region previously thought to only represent those properties of an object that can be directly viewed such as its size, shape, location and texture.
“We are working on various projects to determine how the brain produces actions on the world,” explains Dr. Gallivan about the work he is undertaking at the Centre for Neuroscience Studies at Queen’s. “Simply looking at an object doesn’t provide the brain with information about how much that object weighs. Take for example a suitcase. There is often nothing about its visual appearance that informs you of whether it is packed with clothes or empty. Rather, this is information that must be derived through recent interactions with that object and stored in the brain so as to guide our movements the next time we must lift and interact with that object.”
According to previous research, the ventral visual cortex supports visual processing for perception and object recognition whereas the dorsal visual cortex supports visual processing for the control of action. However, this division of labour had only been tested for visually guided actions like reaching, which are directed towards objects, and not for actions involving the manipulation of objects, which requires access to stored knowledge about object properties.
“Because information about object weight is primarily important for the control of action, we thought that this information might only be stored in motor-related areas of the brain,” says Dr. Gallivan. “Surprisingly, however, we found that this non-visual information was also stored in ventral visual cortex. Presumably this allows for the weight of an object to become easily associated with its visual properties.”
In ongoing research, Drs. Gallivan and Flanagan are using transcranial magnetic stimulation (TMS) to temporarily disrupt targeted brain areas in order to assess their contribution to skilled object manipulation. By identifying which areas of the brain control certain motor skills, Drs. Gallivan and Flanagan’s research will be helpful in assessing patients with neurological impairments including stroke.
The work was funded by the Canadian Institutes of Health Research (CIHR). The research was recently published in Current Biology.

I gotta say Ricky ! Cause he was completely innocent..had a child and was making moves to leave the hood ! Then he gets killed smh
I only seen one of these movies.
Cleo for me..hate scene and the music makes it worse lol then Ricky’s.
Cleo, all the girls death tbh
It’s between Ricky & Raheem for me
I cry every time I see Ricky die!
Korrasami selfie.. at the beach.
Wee bit of fanservice! I’ve never been good at drawing asami well ( 4gifh me pls OTZ ) oh well atleast korra looks good :’D amaright?
Pencil sketch from my sketchbook + quick photoshop of colors..
Also I hit 311 followers. Yey ! little milestones. thanks a bunch, it means so much to me. (srsly ;_; )
Goodnight ! ( its 2am actually fml )

You’ve probably seen those intriguing paintings of iconic hip-hop artists like Notorious BIG or Tupac painted as 17th century royal figures floating around on Complex, The Cotton Candy Machine, or even Buzzfeed, but do you know about the man behind the brush?
these photos were taken earlier this year when I attended school in Tennessee (my 4th year to be exact)
I don’t know if you can tell but I was very sad at the time…
Sad is actually an understatement… I had actually never thought about suicide before going to a religious school… But it’s just something about being surrounded by people who care about everyone else but the ones they are supposed to care about… People who set out to “help the broken” but who were too blinded by their own hypocrisy to help the broken ones right under their stuck up noses… I never would have guessed I would be sleeping in my car and in hotels all while trying to get my education at a place that literally hated me… Or the idea of what I represented.
This piece, “Overhead” was one done in response to being told “create a work about how you are feeling”
At the time I felt so empty and lonely that it physically hurt…
"Overhead" represents the idea of a dark cloud overtaking a persons’ life… How the feelings of sadness can have a physical weight of it’s own… A presence if you will…
I spent 5 days/nights (even after the piece was due) to finish this room sized installation. It consisted of over 500 fishing lines attached to a 15 x 20 ft grid and pounds of scrap bubble wrap …
I did not finish the piece on time even when I asked for an extension… I just wanted to do my best..in my mind, it would all pay off…
It didn’t. My professor: a racist homophobic sexist conservative man took it as his opportunity to put me in my place… To break me… he didn’t even look at the piece once it was done.. It was up for a week… He was so mad that I had finished it.. At the end of the year he failed me….and ONLY me..an advanced sculpture student who had always made A’s and who had received scholarships for my work…
Fast forward to now… I wish I could have told the person I was a couple months ago that everything was going to be ok…
I’m now in NYC. Things are not perfect (I don’t have a degree after almost finishing school) but I wouldn’t trade it for the world.
Tennessee broke me… and even thinking about “Overhead” brings back terrible feelings and resentment… But I’m so thankful it did. I was meant to be pushed away from that place.
I’m free.“Just like a dark cloud everything passes.”
…if it comes to pass, I hope it happens.

"i’m not saying that things don’t change. i’m just saying that, structurally, they reproduce and mutate."
"there is something about racial empire and its consumption of the black body that is without analogue."
"the construction of democratic virtue exists hand and hand with the enslavement of black bodies. and since democratic virtue is sold to the world as the gold standard, that i think, makes this unique. does that make it the worst atrocity in the world, no. it just happens to be the one that i’m living through."
"what does it mean to go? what does it mean to take flight?"
"i would like to think of a liberated ideological territory, in which being wedded to a two-party system or acquiescing to a lesser of two evils or ‘this this the best that we can get’ is understood as a dumbing down."
"audre lorde talks about the difference between the erotic impulse and the pornographic impulse. the erotic is life-giving, it’s intimate, it’s sustaining, it’s about community. the pornographic is about power and domination. for me, democracy is a graveyard is a pornographic culture. and so what does it mean to embrace eros in the face of it? whether or not it’s going to be triumphal? … it doesn’t mean that you’re going to build the new world or that people are going to flock to it. but it just means that you’re not restricted by notions of humanity shaped by a consumer culture, embedded in empire where the marketplace dominates everything. that you have a vision beyond that. and can you deliver anything that’s going to be comforting? probably not.
but flight has its own beauty.”
just watch this shit. it is so important.
