Understanding how brain networks coordinate to enable intelligent behavior
How do visual perception and spatial memory systems interact to enable intelligent behavior? This fundamental question drives our research program.
Our lab uses precision neuroscience approaches to examine individual brains across spatial scales, from molecular to network levels. By combining ultra-high field 7T fMRI, advanced computational modeling, magnetic resonance spectroscopy, and virtual reality, we reveal coordination mechanisms invisible to traditional group analyses.
We recently discovered non-canonical retinotopic coding in memory areas, challenging traditional models of how perception and memory systems interface. This finding opens new avenues for understanding brain-wide communication and has implications for cognitive aging and neurological disorders.
We investigate how the topography, connectivity, and neural coding of brain systems facilitate cognitive tasks. Our recent Nature Neuroscience paper revealed negative population receptive fields in memory areas, challenging traditional models of perception-memory interfaces.
Using ultra-high field 7T fMRI and advanced computational methods, we map individual brains from molecular to network scales. This individualized approach reveals coordination mechanisms invisible to traditional group analyses.
We examine how brain anatomy, physiology, and neural coding changes across learning and aging, with implications for understanding cognitive decline, Alzheimer's Disease, and Post-traumatic Stress Disorder.
We use 7T fMRI to achieve unprecedented spatial resolution, allowing us to examine brain organization at the voxel scale and reveal fine-grained functional architecture.
Advanced population receptive field modeling and encoding approaches help us decode neural representations and understand how information is structured in the brain.
Immersive VR environments allow precise control of visual and spatial experiences while participants navigate and remember complex scenes.
MRS techniques measure neurochemical concentrations, linking molecular-scale processes to systems-level brain function.
