Re: [escepticos] Más sobre el belga en coma

[Carlos Dominguez]

Entre los comentarios al post de PZ, está éste sobre los mapeos
cerebrales  de personas en estados vegetativos que me parece
interesante:
Las técnicas de  imagenes diagnósticas en estos casos deben ser tomada
con escepticismo, y la "comunicación facilitada" ya es sabido que es
charlatanería (Lilkienfeld se dedicó a ella in extenso)-

Wahoo, finally a Neuroscience story allowing me to go from
enthusiastic Pharyngula-reader to commenter :D

Laureys is not a kook. He's got strong opinions that aren't widely
accepted, but the vegetative / minimally conscious / comatose arena is
hugely complex and there are's no consensus about a lot of these
tests. The best - and shortest - article I've read on the subject is
this one.

http://perso.univ-rennes1.fr/pascal.benquet/index_fichiers/science%20FRMI%20vegetatif.pdf

This is an fMRI study where a minimally conscious (ie, no behavioural
responses at all) patient's neural activity was compared to that of a
healthy control, while performing mental imagery tasks, such as
'imagine yourself playing tennis'. They show activity in very similar
brain areas (though reduced in intensity), which is unlikely just to
be due to hearing the task instructions... it's far more likely that
this activity is produced by *following* those instructions. Where
there's someone to listen and obey instructions, there's something
like a conscious agent locked inside, who can hear and respond. No FC
here, and no wild claims, but a distinct possibility that all is not
what it seems in this patient.
