drugs like ritalin, adderall, modafinil .. that i think target Dopamine neurotrasmitter?

Wooh, big difference between these three! (SEE LIBRARY; DRUGS & CHEMICALS SECTION)

[s] the people who take it and says they experiment better "concentration" (especially people with ADD/ADHD) they achieve better concentration "indrectly" i mean, just because they have more alertness, and more desire (behaviour of explore) because of dopamine but not because in directly increase their concentrarion?


I'm not absolutely sure I understand you here but firstly, there is a common problem with qualitative data. To fully understand what's being experienced, we would need to know which people say this, talk to them extensively, and try to find out what exactly do THEY mean by 'concentration' or 'alertness' or 'desire'? Because we are not experiencing their feelings for ourselves, it's difficult to be sure whether they mean (what we call) attention, alertness, awakeness, interest, motivation, desire, excitement, concentration, observation, orientation or focus.

You see the problem here? The members of the general public who take these drugs ordinarily don't have much knowledge of physiological or psychological terms; they use words like 'concenration' in the colloquial. Unless someone is looking at intelligence from the same background model as yourself, it's hard to be sure what they mean.

Because each of these states has a different chemistry, though, it IS possible to measure changes in the brain. If these are combined with qualitative statements from the same persons, then we can decipher what's going on.
You could try searching for 'imaging cohort studies/(name of drug)', or wait ages until I've got time to explore this further...


[s] (because it seems it is in N3 and not N2? and it need Oxytocin..?

What we call 'Concentration' as the chemical & physiological state that we describe as the first stage of learning, is accomplished by merging the skills of (what we call) Attention and Orientation. Basically they enable you to direct your senses at a thing and move them to remain pointing at that thing (N1 & 2) Employing those skills together enables Concentration in N3.

So altogether it the process needs Serotonin (so you stay attentive and receptive for long enough to gather data), then dopamine (so you orient yourself to where the data leads you and get motivated to go looking for more) then Oxytocin in N3 for (what we call) Observation so you can pay attention to something with a view to copying it, to adapt yourself to be more similar to it.

This is a whole new kind of attention experience, because it employs imagination as well as concentration.
Obviously you need other transmitters for the other stages of COMP...

Re: mindfulness; if you're achieving the relaxation response by whatever means, you are benefiting all networks.



[s] awareness/attention (they are the same stuff?)

No. Awareness is sentience (before star trek got hold of the word). It literally means 'able to receive information via the senses'. Attention is pointing your senses at the thing worthy of attention.

Alertness is a more proactive, controlled process and is tied to our sleep/wake cycle, concepts of order and focus. It's the state for practice, stamina, tenacity, staying power and it depends on acetylcholine and the employment of alpha rhythm. At its best it enables that space creative people athletes and gamers call "the zone".
Hope this helps!
