I think they operate on a much more frequent level, every second there is phasic activation of many gabaergic neurones...hm, theres a lot on this, but i think there can be a link, normally when i think of tonic/phasic i think of role in modulating the orchestration of neurones into sysmtes in the brain, and the information processing stuff. i liked maths but reading calculus and statistics is just too much for me to remember. but tied in with bipolar, it could be analogus to epilepsy kindling, at least thats what i think of when i think of improper gaba neurone patterns, the improper synchronizing of neurones in the brain.

> i was also thinking then that 'normal' serotonin levels would be phasic, and when a person becomes depressive the serotonin takes on a tonic attribute. thus why some AD's make you manic, not needing a serotonin LEVEL adjustment, but just need a 'current adjustment'...

i think something like this might be the case with the locus caeruleus and norepinephrine... i think phasic activation is reduced by methylphenidate, so behaviour is less activated, tonic is increased, more attentive to surroundings...

good to bring this up, instead of just 'more vs. less' of a transmitter...it all matters, circuits/location, pattern of activation, interplay with immune system, etc.
