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