Likewise, if my help could be useful in developing this, and if a time-turner can be acquired, I'd be delighted to help. Questionnaires/surveys aren't the sort of methodologies I typically use, but my research is in the area of perception and - increasingly - neuroscience, so I may be able to bring something useful to the table possibly. But, yeah, some sort of day-increasing device may be needed. What with my PhD to complete this year, and my DiPT-research in my spare time; I'm all researched out at the moment, really.
ETA: This may be an obvious/silly question, or it may be one more suited to ADD, I'm really not sure... Presumably (since at least a contrast between DiPT and any typical psychedelic should make it obvious that different sensory systems may be affected differentially by different psychedelics) some structures are better at playing with receptors in some areas of the brain than others, regardless of the expression of the relevant receptor types across regions... The same person (with a given distribution of 5HT2 receptors in their auditory and visual cortices) will experience auditory distortion on DiPT and visual distortion on 4-HO-DMT, say. Do we know (or is there any indication) of the sort of factors and mechanisms that determine which bits of the brain (regardless of receptor expression) a given chemical will be able to target? Is it to do with whether the chemical can physically get into the relevant part of the brain (e.g. DiPT is better at getting into the auditory cortex)? Or is it to do with different subtypes of receptor in different regions of the brain (e.g. 5HT2 receptors in the auditory cortex are structurally different from those in the visual cortex, and this difference makes them more amenable to the structure of DiPT)? Or something entirely other? (Conceivably, an alternative would be that the differences aren't at the level of the specific sensory cortices, but in the connections between the sensory cortices and integration regions.)
Oh, and a supplementary question... To what extent do we know what parts of the brain are directly affected (i.e. the drug reaches and acts on receptors in those regions; as opposed to indirectly stimulating activity in other areas, as a knock-on from the activity caused directly) by psychedelics (I know a fair amount's known about which receptors are affected, but I've not heard of much on which brain areas are involved). I guess this would require a radio-labeled psychedelic to investigate this, right?
ETA: On reflection, this question could clearly benefit from being asked in ADD, so I'll post it over there.
