- To scale or not to scale: McCarthy and Wood revisitedA R Haig
Department of Psychological Medicine, Westmead Hospital, NSW, Australia
Electroencephalogr Clin Neurophysiol 103:323-5. 1997..Furthermore, we show that the two main forms of scaling they proposed may distort or even completely eliminate real differences in scalp topography reflecting genuinely different underlying sources...
- Peak gamma latency correlated with reaction time in a conventional oddball paradigmA R Haig
University of Sydney, Department of Psychological Medicine, Westmead Hospital, NSW, Australia
Clin Neurophysiol 110:158-65. 1999..To determine whether a relationship existed across trials between evoked gamma and reaction time in a conventional cognitive ERP paradigm...
- Gamma activity in schizophrenia: evidence of impaired network binding?A R Haig
Cognitive Neuroscience Unit, Westmead Hospital, Sydney, Australia
Clin Neurophysiol 111:1461-8. 2000..Impaired temporal integration may be a key feature of the associated disturbances in schizophrenia. This is the first study to examine the time course of Gamma activity induced in response to stimuli in this disorder...
- Prestimulus EEG alpha phase synchronicity influences N100 amplitude and reaction timeA R Haig
Department of Psychological Medicine, University of Sydney, Australia
Psychophysiology 35:591-5. 1998..In addition, RT was significantly reduced in the high prestimulus alpha phase synchronicity cases. Alpha phase synchronicity reflects an aspect of brain state that influences subsequent stimulus processing...
- Sex differences, gamma activity and schizophreniaS Slewa-Younan
Department of Psychological Medicine, University of Sydney, NSW, 2006, Australia
Int J Neurosci 107:131-44. 2001..The patient group however, failed to show this male lateralized and female frontal-posterior pattern of Gamma activity, suggesting suboptimal network integration in the patient group, in both males and females...
