In the Attention Perception and Performance Lab we use and develop cutting edge cognitive neuroscience techniques to study the human brain in its natural habitat. We use EEG, ERPs, Psychophysics, Optical imaging, Electrical Stimulation, fMRI, and Neurofeedback to study human performance and perception in both laboratory tasks and also in real world activities like bike riding.
Ecologically Valid Cognitive Neuroscience
We use bike riding as a model real world activity due to its low motion of the head and neck. We have a protocol to collect ERP’s in auditory oddball tasks during bike riding
We use miniaturized computers to produce well controlled experimental stimuli and send markers to the EEG systems. We use portable EEG systems able to fit in backpacks.
Brain Mechanisms of Attention
We theorize that alpha oscillation represent a pulsating inhibitory mechanism of attention in the brain. We have found that awareness depends on the phase of ongoing alpha oscillations.
Along with colleagues in materials science we design and test adhesive and flexible next generation EEG devices to increase portability.
Optical Brain Imaging
We use and develop systems to deliver near-infrared light into the human brain, and measure the resulting light to estimate neural activity using optical brain imaging.
