What we do
Probe how information is transmitted in brain networks for effective cognitive control
How we do it
Measure neural activity using electrophysiology and neuroimaging during goal-directed behavior
Why we do it
To understand how information transmission breaks down in psychiatric disorders like schizophrenia and ADHD
Cognitive control is the ability to flexibly adapt behavior according to current objectives and context. Our research goal is to show how neural dynamics enable cognitive control.
The lab investigates three major research questions:
- What brain networks execute cognitive control, including selective attention, rule-guided behavior, mental set shifting and memory processes?
- How does the brain code information and regulate information transmission according to behavioral demands?
- How does information processing in brain networks differ between conscious and unconscious states?
We combine neuroimaging and electrophysiology to investigate these questions. We map brain networks using functional MRI and diffusion MRI. Next, we simultaneously record neural activity from interconnected network sites in behaving animals (single-units, local field potentials, microstimulation) and human subjects (intracranial electrocorticography). Our focus is on interactions between neurons in the cerebral cortex, basal ganglia and thalamus.
