In the 21st century, immortality beckons from several directions: cybernetics, artificial intelligence, telomere extension and cell therapy, maybe even an afterlife. But most of humanity's hope to transcend death revolves around the brain, as the manifestation of our memories and personality. On Pharyngula, PZ Myers considers the merits of new efforts to master the brain, such as a "cryonic brain preservation technique" that promises to preserve your dead gray matter for a future generation. PZ used to prepare tissue for microscopy in the same way: "I was chemically nuking all the proteins in the tissue; I was washing out most of the chemistry; I was destroying most of the physiological information to preserve a structural skeleton of what was there." He concludes the pattern of synaptic connections is not sufficient to reconstitute a mind. In another post, PZ criticizes a researcher who could not get approval to surgically implant electrodes in human brains, and so had them implanted in his own. PZ writes, "Transhumanists might dream of some amazing Prigogenic leap that abruptly makes their cyborg aspirations reality, but it’s not going to happen that way."
