Subject: animal brains

Dr. Havelock asked about Suda's and related work updates.

A few years ago, when he was still in the Ukraine, Dr. Yuri Pichugin and 

colleagues worked with rabbit brain pieces on commission for CI, using solutions
similar to CI's, and obtained coordinated electrical activity in networks of 

neurons after rewarming from liquid nitrogen. I believe this goes beyond Suda's
work and is still the most advanced of its kind. A report was published in The 
Immortalist, as I recall.

Dr. Pichugin's recent work for CI has been mostly with rats, not mice, and 
also sheep heads obtained from a slaughter house. Other animals are being 

considered, but not dogs or cats, for proposed work later this year in Russia. 
Human 
cadavers are also expected to be used. A Russian group is expected to help 
with the expense. 

Dr. Pichugin's recent work has resulted in significant advances in the areas 
of vitrification and reduction of toxicity (per the K/Na criterion). But we 
also want full evaluation with microscopy and electrophysiology. We hope to be 
ready for a major change in procedures later this year.
