According to what I know about neurophysiology, a lot is stored in the spinal cord. Apparently parts of complex motor skills are stored in several places (like sensory integration in the parietal cortex, error correction in the cerebellum etc), and actual movement patterns are stored in the spinal cord. When a motor action is started, its regulated and "programmed" by the higher areas, but the actual sequence of signals is generated by a pattern generator in the spinal cord, suitably modulated. In fact, the spinal cord can execute quite complex programs by itself. This is a problem for neurosuspension. While a lot of patterns probably are quite preprogrammed (like walking or crawling), they have individual variations and may be linked in many ways to the brain. Not to mention new motor patterns, which do not exist in other spinal cords. Personally I would prefer to have the spinal cord suspended with the brain, in order to make sure the right conections are made (would it be easier to suspend the entire skull and spine than suspending only the brain?). -- ----------------------------------------------------------------------- Anders Sandberg Towards Ascension! http://www.nada.kth.se/~nv91-asa/main.html GCS/M/S/O d++ -p+ c++++ !l u+ e++ m++ s+/+ n--- h+/* f+ g+ w++ t+ r+ !y -- ----------------------------------------------------------------------- Anders Sandberg Towards Ascension! http://www.nada.kth.se/~nv91-asa/main.html GCS/M/S/O d++ -p+ c++++ !l u+ e++ m++ s+/+ n--- h+/* f+ g+ w++ t+ r+ !y Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=3668
