We use a combination of electrophysiological (ERP, EEG) and functional neuroimaging (fMRI) methods to study the mechanisms of attention and related cognitive processes in humans. Themes include: (1) Attentional and cognitive control; (2) Attentional modulation of perceptual processes; (3) Influence of training on attention; (4) The relationships between attention and reward.
Our primary focus is the understanding of the neural and psychological mechanisms underlying human attentional, perceptual, and cognitive processes. To study these phenomena, we employ a combination of various techniques to measure brain activity, such as event-related potentials (ERPs) and functional MRI (fMRI), while subjects are engaged in cognitive and perceptual tasks.
Mission and Approach
The research in the Woldorff Lab at Duke is aimed toward the elucidation of the neural and psychological mechanisms underlying human perception and cognition, with particularly strong interests in the mechanisms of auditory and visual attention and perception.
To study these phenomena we use various brain imaging techniques, principally event-related potentials (ERPs) and functional MRI (fMRI), along with concomitant recording of behavioral measures. We also have ongoing international collaborations with laboratories employing whole-head magnetoencephalography (MEG).
Our general view is that each of the brain imaging methodologies provides an important but incomplete measure of brain function and activity, and that the most powerful approach is the combined application of several of them. [Attention effects on cortical surface] For example, hemodynamic (i.e., blood-change based) measures of brain activity (e.g., fMRI) are very good at showing which areas of the brain are activated under one sort of a task versus another, or even by one sort of event type vs. another, but they generally provide temporal information only on the order of seconds. Since many perceptual, attentional, and cognitive brain operations occur on the order of tens or hundreds of milliseconds, fMRI (at least in its present form) provides relatively little information on the time course or sequence of the functional brain activations underlying such operations.
ERPs and MEG, on the other hand, although they have substantially coarser spatial resolution, [Localization of N20-50 attention effect] provide a millisecond-by-millisecond reflection of evoked brain activity, thereby providing high resolution timing information. In addition, anatomical MRI provides extremely high-resolution images of the neuroanatomical structures of the brain. Thus, combining these approaches holds the promise of revealing not only which neuroanatomical structures are activated during various mental functions, but also what the time course and sequence of these activations are. Such 4-D spatial / temporal information is critical to develop full-fledged neural and cognitive models of brain function.
The study of attentional, perceptual, and other cognitive processes using such a combined multi-methodological approach is the major aim of our research.

Postdoctoral positions in the cognitive neuroscience of attention and perception. Woldorff Lab, Center for Cognitive Neuroscience, Duke University.
We are currently accepting applications for several postdoctoral positions. We employ behavioral, electrophysiological (ERP, MEG), and functional MRI (fMRI) methods to investigate the cognitive and neural mechanisms of visual, auditory, and multisensory attention and perception. Excellent research resources and environment, including high-density ERP recording facilities and state-of-the-art 3T and 4T MRI scanners fully dedicated to neuroimaging research. Nearby clinical resources include Duke Hospital and the adjacent Durham VA Hospital. International collaborative arrangements also allow for full access to state-of-the-art MEG facilities. Desirable candidates will have a background in attention and/or perception research, some expertise in either fMRI or ERP (or MEG) methods, and strong computer skills.
