Many clinical, behavioural and brain imaging studies have suggested that language functions are less asymmetrical in women than in men. Sommer and colleagues challenge this view in a recent review on the outcome of 24 functional brain imaging studies (PET, functional MRI or functional transcranial Doppler ultrasound) that looked at possible sex differences in language lateralization. A vote cou...

Electrically evoked itching has the strong potential to be used to investigate the central processing associated with itching at high temporal resolution by employing magnetoencephalography, electroencephalography (EEG), and event-related functional magnetic resonance imaging. However, it has not been investigated whether time-locked brain activity can be measured using this stimulus, and wheth...

Developmental dyslexia is conventionally defined as " a disorder in children who, despite conventional classroom experience, fail to attain the language skills of reading, writing and spelling commensurate with their intellectual abilities ". There is evidence that dyslexic children are slow in a number of language-related tasks1. Recently, however, speed deficits have been discovered2 even in ...

OBJECTIVE To align the repeated single trials of the event-related potential (ERP) in order to get an improved estimate of the ERP. METHODS A new implementation of the dynamic time warping is applied to compute a warp-average of the single trials. The trilinear modeling method is applied to filter the single trials prior to alignment. Alignment is based on normalized signals and their estimat...

The electrophysiological correlates of insight and non-insight problems solving were studied using eventrelated potentials (ERPs). Participants were given some time to guess Chinese logogriphs and then presented with an answer to judge whether it matched the logogriph. Results showed that the insight trials elicited a more negative ERP deflection (N300-500) than did the non-insight trials in mo...

Membrane potential responses and tentacle movement of the marine dinoflagellate Noctiluca miliaris were recorded simultaneously and their time relationships were examined. The food-gathering tentacle of Noctiluca exhibited slow extension-flexion movements in association with the spontaneously recurring membrane potential responses termed the tentacle regulating potentials (TRPs). The flexion of...

Event related brain potentials (ERPs) provide information about cortical processing in severe neurological patients whose cognitive abilities cannot be expressed in their behavior. In coma, ERPs contribute to the prediction of the outcome. In a vegetative state, ERPs uncover the functional state of cortical processes. The significance of ERPs in the neurophysiological study of consciousness is ...
