Neuronal networks in the hippocampus encode and retrieve information at different phases of the theta rhythm View-invariant object category learning, attention, and recognition Restoring speech to paralyzed individuals How humans efficiently search complex scenes by learning about their spatial and object contexts Advancing a rodent model of Attention Deficit Hyperactivity Disorder Memory system functioning in adult and adolescent rats exposed to cocaine Perception of "forbidden colors" Can lowering the contrast of a moving object improve the perception of motion direction? Is attention required at all for perceptual learning? (or) Where in the brain can learning without attention occur? Gist memory helps older adults when details are forgotten 2008 Understanding the speech of multiple speakers Visually-based navigation in a cluttered world How do small cells code large spaces? From entorhinal grid cell to hippocampal place cell Neural oscillations may code spatial location Speed perception in apparent motion stimuli Restoring speech to paralyzed individuals Understanding natural scenes: From global gist to local textures Remembering the order of events in unique experiences New undergraduate textbook for learning and memory 2007 A laminar cortical model for 3D boundary and surface representation of complex natural scenes How do we see objects move?
