About the Lab

My Lab

The goal of the research in our laboratory is to understand how the brain perceives and attends aspects of the visual environment. Our studies examine conscious and unconsciously perceived objects, scenes, sequences and sounds using a combination of experimental techniques: psychophysical measures of behavior, functional Magnetic Resonance Imaging (fMRI), Electrophysiology (EEG) and Voxel Lesion Symptom Mapping (VLSM).

Our lab is interested in applying a better understanding of the behavioral and neural mechanisms of attention to patients with related deficits following brain injury (e.g., Hemispatial Neglect, Balintís syndrome). Our aim is to gain a better understanding of the mechanisms of attention and to identify effective means of rehabilitation.

Our prior work has examined neural networks mediating attention, and the breakdown of these networks in neurological disorders such as Hemispatial Neglect. Examination has occurred at several levels:

  • Examination of the effects of environmental manipulation or training on recovery in patients with neglect and in animal models of neglect (Burcham, Corwin, Reep & Van Vleet, 1998; Van Vleet et al., 2003; DeGutis & Van Vleet, submitted; Van Vleet, DeGutis and Robertson, submitted)
  • Influence of cross-modal manipulations on the spatiotemporal dynamics of awareness in patients with neglect (Van Vleet & Robertson, 2006)
  • Examination of pharmacological agents affecting recovery in animal models of neglect (Van Vleet et al., 2003)
  • Analysis of underlying neural substrates of attention related to neglect and recovery from neglect (Reep, Corwin, Cheatwood, Van Vleet, Heilman, & Watson, 2004; Van Vleet et al., 2000; Van Vleet & DeGutis, in prep)
