obsteve 21-Apr-11, 15:37	Multiple Body Transplant If aobsteve and his 2 brothers were involved in an horrific car accident, where aobsteve's body was destroyed and the brains of his 2 brothers, bobsteve and cobsteve, were destroyed, I think the sensible thing to do would be to transplant half of aobsteve's brain into each of his brother's empty skulls. But would obsteve see through the eyes of bobsteve or cobsteve?
obsteve 21-Apr-11, 17:54	or are there 2 aobsteves?
obsteve 21-Apr-11, 17:59	err or none?
antinephilehi 22-Apr-11, 05:19	Will two half make one ? Hope your brothers where two very vlose twins.
obsteve 23-Apr-11, 11:46	Hi Neph re: "Will two half make one?" No, after the accident bobsteve's body (with the left hemisphere of aobsteve's brain) will move to Australia, while cobsteve's body (with the right hemisphere of aobsteve's brain) will move to Canada. Both bodies have enough brain to function
antinephilehi 23-Apr-11, 12:03	Who's eyes? Don't really know. As long as they don't work as Taxidriver. What are the to answer the customer? "Are you talking to me?"
obsteve 23-Apr-11, 13:09	bobsteve's body (with the left hemisphere of aobsteve's brain) we could call Lefty. cobsteve's body (with the right hemisphere of aobsteve's brain) we could call Righty. Actually, both Lefty and Righty could work as "taxidrivers", where only having half a brain is not problematic
antinephilehi 24-Apr-11, 10:20	Who am I ? Just muscular and some fat,a few nervcells.Or is there more to it then that? I think.Therefore I exist.But with only half a brain,is it only half true? What we really should worry about is if a medic reads the idea.He would kill the thread along with a,b and c-person.
obsteve 24-Apr-11, 13:51	Hemispherectomy I just looked it up: en.wikipedia.org "Studies have found no significant long-term effects on memory, personality, or humor after the procedure,[2] and minimal changes in cognitive function overall." ok, so body transplants not yet possible- but they might be one day! en.wikipedia.org so given that both halves of aobsteve's brain continue to think, the "I think therefore I exist" maxim would suggest aobsteve continues to exist in 2 locations...
antinephilehi 24-Apr-11, 22:06	But since we are in the process of learning what will happened,Perhaps it is only half the truth

obsteve 25-Apr-11, 02:07	true however, I am less keen on the other options- i) aobsteve continues to think/exist as a "person" in 2 locations, ii) aobsteve continues to think/exist as 1 "person" in only Lefty or Righty iii) aobsteve ceases to think/exist as a "person" at all (bobsteve and cobsteve continue to exist) my worries about scenario i are, how can a "person" exist in 2 locations? with scenario ii I worry that the other body would be left operating without a "person" in it. As for scenario iii, I think this would mean that a true "body transplant" is logically impossible. (sorry about the deleted message above, I noticed a typo that rendered it more confusing!)
obsteve 26-Apr-11, 17:01	partial brain transplant ok, so the challenges with total body transplant are presently insurmountable, it seems. SOmething to do with the difficulty of repairing scarred nerve tissue, and also "reconnecting" the correct nerves. However, partial brain transplant seems relatively nearer realisation www.scienceblog.com I wonder how much brain tissue would need to be transplanted in order to maintain a sense of identity in the transplanted cells? And I wonder what it might feel like, a) to be the receiver of said brain portion, and b) to be the identity carried in said brain portion?
antinephilehi 27-Apr-11, 09:37	I wonder to. Another Q:If "the me" is in the brain then it isn't really a brain transplant but rather a "body transplant"?
