It would be nice if the article didn't have a section describing various lesions and their effects on behaviour, and then at the end make the vague and poorly supported statement "If there is a lesion in the PAG, then consciousness is lost." 184.108.40.206 (talk) 04:58, 2 March 2016 (UTC)
Thanks for pointing this out. I have removed that section of the article, as the statements are at best oversimplified, and in any case are not adequately supported by the cited sources. I don't even think it is possible to lesion the PAG without also damaging other critical circuitry that is intermingled with its elements. Looie496 (talk) 14:43, 2 March 2016 (UTC)
