on both calls so far the questions have been few and dominated by multiple questions from a few people that are off topic. Submittting them during the conference and choosing focused questions that will at the same time teach something would be more succesful. When you only have an hour, there is no time for anyone to be too wordy.My questions were:

What is the spinal tap for? i was hoping it would yield info about other transmitters.

can neurotrophic factors cause cancer cells to grow if one has cancer?
