I took this from another board I posted on. Noone could really answer much of it. Please no debate about what intelligence is. I couldn't find a neuroscience message board, but I have some questions, so I'm hoping someone can answer them here. What exactly makes one intelligent. Is it the structure of the brain, or how well the brain is running? Can things change the structure of the brain, or the connections between neurons. SSRI's keep S bouncing around the synapse, so don't they send errant messages. I'm so worried that meds will change the structure of my brain, or destroy some connections. I know nothing about neuroscience. How does xanax work? I know that many drugs can destroy the brain. Can someone at least point me in the direction of a place where I can get these questions answered? Thanks. Ok, well the word intelligence isn't important. I could have us heightened consciousness, awareness, or anything of that sort. By intelligence I mean being able to think through logical steps, control thoughts, ground one's thoughts, tranform feelings into words, manipulate feelings that represent ideas, and so on. A "crack head" is not intelligent, no matter what exactly the word means. We have ideas about what it is. Anyway, do these drugs change the structure of the brain or destroy connections between neurons at all. Benzos or SSRIs. Xanax actually makes me feel more "intelligent" for a while, and then makes me feel less afterward. I just don't want to mess anything up. I like the way I think and I don't want it to change.
