Do you have access to the full paper?
No, but I read summary in Russian chemrar.ru/u-mozga-nashli-c...
Thanks for the link. Though it's still the summary. I was curious what drug(s) did they try. It's a little bit more specific in the Russian abstract "anti-epileptic" vs "anti-seizure". The last sentence of the abstract generalize it "for drugs targeted to the central nervous system". I guess it may work for many supplements that we discuss here which have low bio-availability due to BBB crossing limitation.
That picture of a mosquito . It would make sense that the brain would keep out anything during a time period when higher probability of mosquito contact would occur and open to be more receptive when it is safer. Very interesting thanks for posting. Are you in Russia now?
