i've read that parnate has a few cases of pitch shift disorder, and was problematic for professional musicians....
also, i think a lot of meds can cause temporal disturbances.
mary jane sure does. stims do. anti-psychotics-yep.
temporal and olfactory hallucinations are some of the most common throughout the populace as a whole.i forget what med's your on, but music is a complex emotionally active perception, anatomically close to pitch perception, emotion, and language. personally, my favorite music, squarepusher and other various electronica artists will vary their time signature measure by measure.
i don't think its too uncommon, also benzo's and their relatives can interfere with memory and cause various forms of amnesia.
often when life is good, time flies, when its when it's really rough i notice it will slow to a crawl....
time is a western human concept. remember dali's "persistence of memory". in the states, native americans, the hawaiians, new mexicans work on manana time, as well as italy, spain, etc. they have vastly different relationships to time than those whose lives revolve on clocks rather than seasons...
as far as i know, temporal perception is a pretty complex process not just limited to the temporal cortex, but is though of as a cyclic curcuit that creates rings of energy throughout the cortex including the prefrontal lobes.
a good old meditative practice was to look at the second hand on a watch and attempt to make it stop entirely...
i don't even think about this stuff anymore, perception is just a construct, hell i'm an artist an can practically hallucinate on demand.
but if you have very specific and worrisome effects, i'm not sure an eeg is gonna do much except show the possibility of epilepsy during an attack. for brain damage/strokes mri's and cat's are used. eeg's aside from biofeedback, are mainly used to diagnose sleep disorders. i have one, and it's pretty hard to make sense of the tremendous amount of data they produce. the science is moving forward, but for diagnostic criteria its only mostly used to diagnose narcolepsy, cataplexy, apnea, and ones sleep.
it only shows epileptic activity during an attack. its a very crude diagnostic device, but eeg biofeedback has proved its efficacy for treating ADHD, and epilepsy, and some affective disorders, autism, and mental retardation, or severe brain damage through learning to control various aspects of the type ones brain activity.
it doesn't fit the criteria for double blind research, but insurance companies now cover it as an alt to stims for kids with ADHD.
