Headline:
Brain activity of patient in vegetative state responds to instructions.

Method

Functional Magnetic Resonance Imaging (fMRI) was used to measure neural responses in a vegetative state patient and twelve healthy control participants.

Experiment 1: participants were presented with spoken sentences

(e.g. “there was milk and sugar in his coffee”).

Experiment 2: participants were instructed to imagine either visiting different rooms in a house or playing tennis at different points during the scan.

Results

Experiment 1: speech-specific neural activity (in bilateral middle and superior temporal gyri regions) was observed in both the vegetative state patient and controls (no difference).

Experiment 2: brain activity specifically corresponding to the mental imagery tasks was observed in the patient (tennis task: supplementary motor area; spatial navigation task: parahippocampal gyrus, posterior parietal cortex and lateral premotor cortex).

Again these results were indistinguishable from those of controls.

Is this summary missing some information?

Anyone got a good review paper on the posterior parietal cortex?

Check out this weeks Panorama on BBC1 - it's all about this research!

If you like this paper - you should check out Adrian Owen's 2010 paper - it's a cracker!

Does anyone know of any papers that are similar to this one? It's really interesting and highly relevant for a project I'm working on.

Most amazing research I've heard of this year. Please send me to Adrian Owen if I ever end up in a vegetative state!
