We have currently only looked for it in the hippocampus - that was what our original funding payed for... It should be noted that increasing neurogenesis in the hippocampus using plant-based compounds is pretty cool! We have some ideas about other areas that we want to check, though, and this is exactly the type of exploratory (e.g., somewhat risky in terms of return-on-investment) pilot data that could be generated with these donations. Last week we got a little over 2.5 BTC, which is enough to buy about 700 slides (which is about enough to mount slices of these other brain areas from 1 experiment). A few more would cover the histology reagents and cutting blade costs - with these, we could generate some (potentially) innovative data with micro-donations that a peer-reviewed grant would not have funded (the hippocampus has a much higher chance of success when looking for neurogenesis)....
