Effect of addiction on the brain

[theoristo]

the TEDtalk by Psychologist Philip Zimbardo asks, "Why are boys struggling?" He shares some stats (lower graduation rates, greater worries about intimacy and relationships) and suggests a few reasons -- and he asks for your help! Watch his talk and Gary wilson's too ,the admin said I can't post so go look for it on youtube.

He talks about arousal addiction especially ...the title is the demise of guys.

Another interesting report.

here the paper I got it from http://www.ncbi.nlm.nih.gov/pubmed/21499141

Ok that about "reducing dopamine receptors" (probably on the post-synaptic neuron) and is a consequence (I believe documented) of excessive dopamine in the synapses: the body adjust to excessive levels by decreasing the number of receptors. I believe that's the case anyway. I did not read the paper.

It's a study about the irregularities in the dopaminergic brain system associated with addiction.

Here 's a newer study about the role of prefrontal cortex and the midbrain dopamine system.

if you can't read all the study just read the abstract.

Ok look, if "intelligene is not really understood" as you say, then how can we have a scientific discussion about it? But no wait, that depends on what you mean by understood. I bet there are a bunch of things we DO know about intelligence. Maybe if you focus on those and then try to see how addiction affects those things. And I think I'm right: whatever those things are, they will have a neurochemical component.

Yes of course there is a neurochemical component to intelligence but you can't examine it and link it directly to intelligence. The knowledge and technology just isn't there. It would be better to examine how people perform certain tasks like in the German paper on sexual images and working memory we discussed on the first page.
