QUOTE: "If we perturb the global positional information of the system, these cells get placed in the wrong positions, and then axons go to the wrong positions—so we think there's a positional information framework that places the cells during regeneration,BB and that allows them to work as guideposts in the correct locations." (David's bold)

DAVID: interesting that muscle cells are co-opted for this role which is usually by astrocytes. Note in my bold the use of the word 'information' which always disturbs dhw. A perfectly reasonable usage. Not by chance. Design fits.

dhw: I have no objection to the word “information” until it is used in such a way that it requires a new definition which writers fail to deliver. A classic example: “Information as the source of life”.

See today's entry from Stephan Talbot's thoughts about the 'ghost in the machine'. it is information.
