hi we've never met i think we should remedy that

i seriously considered psychology, i adore it, but i dont think im interested so much in research as i am in treatment so i decided on social work as a happy medium. ^^;

yes! i am!! my roommate seems very nice so far, we're excited about decorating the room cause we both love vintage stuff and black and white movies and pink and purple and girly stuff askdfdksl. shes a music ed major and i think im going into english lit or social work, or both. 83

yeah C: *huggu* <3

ive been really super boRED and ready for college to start ahhhh!! seeing steve was awesome perfect amazing omg ;n; hopefully ill visit again at christmas

hi hi~ how are you feeling steph? <3

You could say that ;P

you are more than welcome to sodomize me as well sugah

y0 girLLL wAsSuP?!?!?!?!

STEPH BABY IF YOU EVER SEE THIS. MISS YOU BABE. GIVE ME A RING ON FUCKING MESSENGER GAWD

I hope you don't mind me asking, but I'm curious about what you said in the college essays thread about the time perception and colors, the PTSD, etc. Is this something you've dealt with personally?

This is probably coming out of the blue, but I due have some form of generalized anxiety and I deal with those kinds of symptoms.

Right. We can't extract specific thoughts/words from a person's mind. And I don't think we'll ever be able to-- not just because we don't know how, but experiments that would try to do so would never, ever get through any sort of ethical review boards.

So it's all very general then, right? And sorry, I mean chemical/electrical reactions within the brain. You can get a sense of what people feel or think but not any specifics, right? Like you could say, "oh that person is in physical/emotional pain" but you can't say "because his cat lost a poker game"?

I can't seem to respond on your page, so I'll respond here.

I am not exactly sure what you mean by "reactions?" Reactions to what? Emotions? A visual scene? A moving ball? A break up? What they're thinking about?

As of right now, we can "mind read" very basic reactions. I'll use the visual system as an example. There is a primary visual center in the brain. Before reaching this center, the visual information we see are just pieces. We have lines and edges, color, motion, etc. The brain pieces this information together in the visual cortex (oversimplified statement).

Neurons are what carry information and spark activity in the brain. Our brain reactions are just neurons firing electrical and chemical signals. On a very basic level, neurons "respond" preferentially to specific stimuli. There is an area called MT in the visual cortex that responds almost exclusively to movement. Within MT, there are neurons that respond to specific types of movement. Some neurons may fire when a stimulus moves from left to right, but not from right to left.

There's a saying in Neuroscience-- "Cells that fire together, wire together." So we have clusters of neurons grouped together that respond to a specific action. Say a subject views a red ball bouncing up and down. The neurons that prefer the color red will fire more strongly than neurons that prefer blue. The neurons that prefer up/down movement will also respond more strongly than ones that prefer right/left. Subjects will give consistent activation of this neurons every time they view that bouncing red ball.

Scientists can record what this activation is. They sum the activity of all the neurons and see which ones are responding more strongly-- this is called population coding. After many trials, they can determine that Cluster A of Neurons likes the color red, and Cluster B of neurons likes up/down motion.

So say in an experiment, researchers play random clips of simple images and record the activity. Using the population coding, scientists can "read" the activation of the neurons and pretty accurately say that a subject is viewing a red ball that is bouncing up and down.

Things are far more fuzzy when it gets complex, however. What about overlapping images? What about pictures of people? What about different sizes and textures of the stimuli? What about emotional reactions to an image?

Just a question because me and a friend had an argument about this once (and I'm not educated about this at all). Say, potentially, someone could literally see or feel all those crazy reactions going on within your brain and have been educated to the degree that they could interpret what they mean; to what degree would this be like 'mind-reading'?

Sup.

i need your number first gorgeous

i like where this is goin

we should hang out some time

speaking of 'staff' section you give me erections

multiple erections
