Response to Comment on “Preserved Feedforward But Impaired Top-Down Processes in the Vegetative State”
Wethank King et al. (1) for deconstructing our paper (2) showing impaired top-down processes in the vegetative state (VS). We hope our responses provide some useful clarifications. (i) Regarding the number of patients, it would have been disappointing not to have found a common abnormality in eight well-defined VS patients. If we had needed 50 patients to obtain significant differences, we woul...

Boly et al. (Reports, 13 May 2011, p. 858) investigated cortical connectivity patterns in patients suffering from a disorder of consciousness, using electroencephalography in an auditory oddball paradigm. We point to several inconsistencies in their data, including a failure to replicate the classical mismatch negativity. Data quality, source reconstruction, and statistics would need to be impr...
متن کاملPreserved feedforward but impaired top-down processes in the vegetative state.
Frontoparietal cortex is involved in the explicit processing (awareness) of stimuli. Frontoparietal activation has also been found in studies of subliminal stimulus processing. We hypothesized that an impairment of top-down processes, involved in recurrent neuronal message-passing and the generation of long-latency electrophysiological responses, might provide a more reliable correlate of consc...
متن کاملComment on "Detecting awareness in the vegetative state".
In a report of a single patient in a persistent vegetative state, Owen et al. (Brevia, 8 September 2006, p. 1402) claimed that the presence of task-specific brain activation in response to verbal command implies both covert conscious awareness and a capacity for intention. We argue that neither can be securely inferred from the evidence presented.
متن کاملthe impact of explicit instruction of top-down reading strategies on reading comprehension of intermediate efl learners
this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
